Here are some events that happened on April 12th. It could be an event or a person that died or was born on that day


1606 – The Union Flag is adopted as the flag of English and Scottish ships.

The Union Jack, or Union Flag, is the national flag of the United Kingdom. The flag also has official status in Canada, by parliamentary resolution, where it is known as the Royal Union Flag. Additionally, it is used as an official flag in some of the smaller British overseas territories. The Union Flag also appears in the canton (upper flagstaff-side quarter) of the flags of several nations and territories that are former British possessions or dominions, as well as the state flag of Hawaii. The claim that the term Union Jack properly refers only to naval usage has been disputed, following historical investigations by the Flag Institute in 2013.

The origins of the earlier flag of Great Britain date back to 1606. James VI of Scotland had inherited the English and Irish thrones in 1603 as James I, thereby uniting the crowns of England, Scotland, and Ireland in a personal union, although the three kingdoms remained separate states. On 12 April 1606, a new flag to represent this regal union between England and Scotland was specified in a royal decree, according to which the flag of England, a red cross on a white background, known as St George's Cross, and the flag of Scotland, a white saltire on a blue background known as the Saltire or St Andrew's Cross, would be joined together, forming the flag of England and Scotland for maritime purposes.

The present design of the Union Flag dates from a Royal proclamation following the union of Great Britain and Ireland in 1801. The flag combines aspects of three older national flags: the red cross of St George for the Kingdom of England, the white saltire of St Andrew for Scotland and the red saltire of St Patrick to represent Ireland.

Notably, the home country of Wales is not represented separately in the Union Flag, as the flag was designed after the invasion of Wales in 1282. Hence Wales as a home country has no representation on the flag. The Flag of Wales incorporates the red dragon.

1945 – Vice President Harry S. Truman becomes President upon Roosevelt's death.

Harry S. Truman (May 8, 1884 – December 26, 1972) was the 33rd president of the United States from 1945 to 1953, succeeding upon the death of Franklin D. Roosevelt after serving as vice president. He implemented the Marshall Plan to rebuild the economy of Western Europe, and established the Truman Doctrine and NATO.

Truman grew up in Independence, Missouri, and during World War I was sent to France as a captain in the Field Artillery. Returning home, he opened a haberdashery in Kansas City, Missouri and was later elected as a Jackson County official in 1922. Truman was elected to the United States Senate from Missouri in 1934 and gained national prominence as chairman of the Truman Committee aimed at reducing waste and inefficiency in wartime contracts. Soon after succeeding to the presidency he authorized the first and only use of nuclear weapons in war. Truman's administration engaged in an internationalist foreign policy and renounced isolationism. He rallied his New Deal coalition during the 1948 presidential election and won a surprise victory that secured his own presidential term.

Truman oversaw the Berlin Airlift of 1948. When North Korea invaded South Korea in 1950, he gained United Nations approval to intervene in what became known as the Korean War. On domestic issues, bills endorsed by Truman faced opposition from a conservative Congress, but his administration successfully guided the U.S. economy through the post-war economic challenges. In 1948 he submitted the first comprehensive civil rights legislation and issued Executive Orders to start racial integration in the military and federal agencies.

Corruption in the Truman administration became a central campaign issue in the 1952 presidential election. After Republican Dwight D. Eisenhower's electoral victory against Democrat Adlai Stevenson II, Truman went into a financially-difficult retirement, marked by the founding of his presidential library and the publication of his memoirs. When he left office, Truman's presidency was criticized, but scholars rehabilitated his image in the 1960s and he is highly ranked by scholars.

1945 Died: Franklin D. Roosevelt, American lawyer and politician, 32nd President of the United States (b. 1882)

Franklin Delano Roosevelt (January 30, 1882 – April 12, 1945), often referred to by his initials FDR, was an American politician who served as the 32nd president of the United States from 1933 until his death in 1945. A member of the Democratic Party, he won a record four presidential elections and became a central figure in world events during the first half of the 20th century. Roosevelt directed the federal government during most of the Great Depression, implementing his New Deal domestic agenda in response to the worst economic crisis in U.S. history. As a dominant leader of his party, he built the New Deal Coalition, which realigned American politics into the Fifth Party System and defined American liberalism throughout the middle third of the 20th century. His third and fourth terms were dominated by World War II, which ended shortly after he died in office. He is rated by scholars as one of the three greatest U.S. presidents, along with George Washington and Abraham Lincoln, but has also been subject to substantial criticism.



Roosevelt was born in Hyde Park, New York, to a Dutch American family made well known by the reputation of Theodore Roosevelt, the 26th president of the United States, and William Henry Aspinwall. FDR graduated from Groton School and Harvard College and attended Columbia Law School but left after passing the bar exam to practice law in New York City. In 1905, he married his fifth cousin once removed, Eleanor Roosevelt. They had six children, of whom five survived into adulthood. He won election to the New York State Senate in 1910, and then served as Assistant Secretary of the Navy under President Woodrow Wilson during World War I. Roosevelt was James M. Cox's running mate on the Democratic Party's 1920 national ticket, but Cox was defeated by Republican Warren G. Harding. In 1921, Roosevelt contracted a paralytic illness, believed at the time to be polio, and his legs became permanently paralyzed. While attempting to recover from his condition, Roosevelt founded the treatment center in Warm Springs, Georgia, for people with poliomyelitis. In spite of being unable to walk unaided, Roosevelt returned to public office by winning election as Governor of New York in 1928. He served as governor from 1929 to 1933, promoting programs to combat the economic crisis besetting the United States.



In the 1932 presidential election, Roosevelt defeated Republican President Herbert Hoover in a landslide. Roosevelt took office in the midst of the Great Depression, the worst economic crisis in U.S. history. During the first 100 days of the 73rd United States Congress, Roosevelt spearheaded unprecedented federal legislation and issued a profusion of executive orders that instituted the New Deal—a variety of programs designed to produce relief, recovery, and reform. He created numerous programs to provide relief to the unemployed and farmers while seeking economic recovery with the National Recovery Administration and other programs. He also instituted major regulatory reforms related to finance, communications, and labor, and presided over the end of Prohibition. He harnessed radio to speak directly to the American people, giving 30 "fireside chat" radio addresses during his presidency and becoming the first American president to be televised. The economy having improved rapidly from 1933 to 1936, Roosevelt won a landslide reelection in 1936. However, the economy then relapsed into a deep recession in 1937 and 1938. After the 1936 election, Roosevelt sought passage of the Judiciary Reorganization Bill of 1937 (the "court packing plan"), which would have expanded the size of the Supreme Court of the United States. The bipartisan Conservative Coalition that formed in 1937 prevented passage of the bill and blocked the implementation of further New Deal programs and reforms. Major surviving programs and legislation implemented under Roosevelt include the Securities and Exchange Commission, the National Labor Relations Act, the Federal Deposit Insurance Corporation, Social Security, and the Fair Labor Standards Act of 1938.

The United States reelected FDR in 1940 for his third term, making him the only U.S. President to serve for more than two terms. With World War II looming after 1938, Roosevelt gave strong diplomatic and financial support to China, the United Kingdom and eventually the Soviet Union while the U.S. remained officially neutral. Following the Japanese attack on Pearl Harbor on December 7, 1941, an event he famously called "a date which will live in infamy", Roosevelt obtained a congressional declaration of war on Japan, and, a few days later, on Germany and Italy. Assisted by his top aide Harry Hopkins and with very strong national support, he worked closely with British Prime Minister Winston Churchill, Soviet leader Joseph Stalin and Chinese Generalissimo Chiang Kai-shek in leading the Allied Powers against the Axis Powers. Roosevelt supervised the mobilization of the U.S. economy to support the war effort, and implemented a Europe first strategy, making the defeat of Germany a priority over that of Japan. He also initiated the development of the world's first atomic bomb, and worked with the other Allied leaders to lay the groundwork for the United Nations and other post-war institutions. Roosevelt won reelection in 1944, but with his physical health declining during the war years, he died in April 1945, less than three months into his fourth term. The Axis Powers surrendered to the Allies in the months following Roosevelt's death, during the presidency of his successor, Harry S. Truman.

Here are some events that happened on April 10th. It could be an event or a person that died or was born on that day


1755 Born: Samuel Hahnemann, German-French physician and academic (d. 1843)

Christian Friedrich Samuel Hahnemann (10 April 1755 – 2 July 1843) was a German physician, best known for creating the pseudoscientific system of alternative medicine called homeopathy.

Hahnemann was dissatisfied with the state of medicine in his time, and particularly objected to practices such as bloodletting. He claimed that the medicine he had been taught to practice sometimes did the patient more harm than good:

My sense of duty would not easily allow me to treat the unknown pathological state of my suffering brethren with these unknown medicines. The thought of becoming in this way a murderer or malefactor towards the life of my fellow human beings was most terrible to me, so terrible and disturbing that I wholly gave up my practice in the first years of my married life and occupied myself solely with chemistry and writing.

After giving up his practice around 1784, Hahnemann made his living chiefly as a writer and translator, while resolving also to investigate the causes of medicine's alleged errors. While translating William Cullen's A Treatise on the Materia Medica, Hahnemann encountered the claim that cinchona, the bark of a Peruvian tree, was effective in treating malaria because of its astringency. Hahnemann believed that other astringent substances are not effective against malaria and began to research cinchona's effect on the human body by self-application. Noting that the drug induced malaria-like symptoms in himself, he concluded that it would do so in any healthy individual. This led him to postulate a healing principle: "that which can produce a set of symptoms in a healthy individual, can treat a sick individual who is manifesting a similar set of symptoms." This principle, like cures like, became the basis for an approach to medicine which he gave the name homeopathy. He first used the term homeopathy in his essay Indications of the Homeopathic Employment of Medicines in Ordinary Practice, published in Hufeland's Journal in 1807.

1829 Born: William Booth, English preacher, co-founded The Salvation Army (d. 1912)

William Booth (10 April 1829 – 20 August 1912) was an English Methodist preacher who, along with his wife, Catherine, founded The Salvation Army and became its first General (1878–1912). The Christian movement with a quasi-military structure and government founded in 1865 has spread from London, England, to many parts of the world and is known for being one of the largest distributors of humanitarian aid. In 2002, Booth was named among the 100 Greatest Britons in a BBC poll.

Having been founded as the East London Christian Mission in 1865, the name The Salvation Army developed from an incident in May 1878. William Booth was dictating a letter to his secretary George Scott Railton and said, "We are a volunteer army." Bramwell Booth heard his father and said, "Volunteer, I'm no volunteer, I'm a regular!" Railton was instructed to cross out the word "volunteer" and substitute the word "salvation". (The printer's proof copy of the Missions' report for 1878 declared "The Christian Mission Is A Volunteer Army", but the corrected proof read "The Christian Mission Is ... A Salvation Army") The Salvation Army was modelled after the military, with its own flag (or colours) and its own music, often with Christian words to popular and folkloric tunes sung in the pubs. Booth and the other soldiers in "God's Army" would wear the army's own uniform, 'putting on the armour,' for meetings and ministry work. He became the "General" and his other ministers were given appropriate ranks as "officers". Other members became "soldiers".

Though the early years were lean ones, with the need of money to help the needy an ever growing issue, Booth and The Salvation Army persevered. In the early 1880s, operations were extended to other countries, notably the United States, France, Switzerland, Sweden and others, including to most of the countries of the British Empire: Australia, Canada, India, Cape Colony, New Zealand, Jamaica, etc.

Often the beginnings in other countries occurred through "salvationist" activities by non-officers who had emigrated. With some initial success they would contact London to 'send officers.'

In other cases, like in Argentina, a non-salvationist told Booth that there were thousands of British people there who needed salvation. The four officers sent in 1890 found that those British were scattered all over the pampas. But the missionaries started ministry in the Spanish language and the work spread throughout the country – initially following the rail-road development, since the British in charge of building the rail-roads were usually sympathetic to the movement.

During his lifetime, William Booth established Army work in 58 countries and colonies, travelling extensively and holding, "salvation meetings."

1847 Born: Joseph Pulitzer, Hungarian-American journalist, publisher, and politician, founded Pulitzer, Inc. (d. 1911)

Joseph Pulitzer (April 10, 1847 – October 29, 1911) was a newspaper publisher of the St. Louis Post-Dispatch and the New York World. He became a leading national figure in the Democratic Party and was elected congressman from New York. He crusaded against big business and corruption, and helped keep the Statue of Liberty in New York.

In the 1890s the fierce competition between his World and William Randolph Hearst's New York Journal caused both to develop the techniques of yellow journalism, which won over readers with sensationalism, sex, crime and graphic horrors. The wide appeal reached a million copies a day and opened the way to mass-circulation newspapers that depended on advertising revenue (rather than cover price or political party subsidies) and appealed to readers with multiple forms of news, gossip, entertainment and advertising.

Today, his name is best known for the Pulitzer Prizes, which were established in 1917 as a result of his endowment to Columbia University. The prizes are given annually to recognize and reward excellence in American journalism, photography, literature, history, poetry, music and drama. Pulitzer founded the Columbia School of Journalism by his philanthropic bequest; it opened in 1912.

1864 – Archduke Maximilian of Habsburg is proclaimed emperor of Mexico during the French intervention in Mexico.

Maximilian I (Spanish: Fernando Maximiliano José María de Habsburgo-Lorena; 6 July 1832 – 19 June 1867) was the only monarch of the Second Mexican Empire. He was a younger brother of the Austrian emperor Franz Joseph I. After a distinguished career in the Austrian Navy as its commander, he accepted an offer by Napoleon III of France to rule Mexico, conditional on a national plebiscite in his favour.

1904 Died: Isabella II, Spanish queen (b. 1830)

Isabella II (Spanish: Isabel; 10 October 1830 – 9 April 1904), also known as La de los Tristes Destinos or the One with the Sad Destinies, was Queen of Spain from 1833 until 1868. She came to the throne as an infant, but her succession was disputed by the Carlists, whose refusal to recognize a female sovereign led to the Carlist Wars. After a troubled reign, she was deposed in the Glorious Revolution of 1868, and formally abdicated in 1870. Her son, Alfonso XII, became king in 1874.

1954 Died: Auguste Lumière, French director and producer (b. 1862)

The Lumière brothers (Auguste Marie Louis Nicolas; 19 October 1862 – 10 April 1954) and Louis Jean (5 October 1864 – 7 June 1948), were among the first filmmakers in history. They patented an improved cinematograph, which in contrast to Thomas Edison's "peepshow" kinetoscope allowed simultaneous viewing by multiple parties.

When their father retired in 1892, the brothers began to create moving pictures. They patented several significant processes leading up to their film camera, most notably film perforations (originally implemented by Emile Reynaud) as a means of advancing the film through the camera and projector. The original cinématographe had been patented by Léon Guillaume Bouly on 12 February 1892. The brothers patented their own version on 13 February 1895. The first footage ever to be recorded using it was recorded on 19 March 1895. This first film shows workers leaving the Lumière factory.

The Lumière brothers saw film as a novelty and had withdrawn from the film business in 1905. They went on to develop the first practical photographic colour process, the Lumière Autochrome.

Louis died on 6 June 1948 and Auguste on 10 April 1954. They are buried in a family tomb in the New Guillotière Cemetery in Lyon.

Here are some events that happened on April 9th. It could be an event or a person that died or was born on that day

1682 – Robert Cavelier de La Salle discovers the mouth of the Mississippi River, claims it for France and names it Louisiana.

René-Robert Cavelier, Sieur de La Salle (November 22, 1643 – March 19, 1687) was a 17th-century French explorer and fur trader in North America. He explored the Great Lakes region of the United States and Canada, the Mississippi River, and the Gulf of Mexico. He is best known for an early 1682 expedition in which he canoed the lower Mississippi River from the mouth of the Illinois River to the Gulf of Mexico and claimed the entire Mississippi River basin for France.

La Salle is often credited with being the first European to traverse the Ohio River, and sometimes the Mississippi as well. It has now been established that Joliet and Marquette preceded him on the Mississippi in their journey of 1673–74, and the existing historical evidence does not indicate that La Salle ever reached the Ohio/Allegheny Valley.

In early 1679, La Salle's expedition built Fort Conti at the mouth of the Niagara River on Lake Ontario. There they loaded supplies from Fort Frontenac into smaller boats (canoes or bateaux), so they could continue up the shallow and swiftly flowing lower Niagara River to what is now the location of Lewiston, New York. There the Iroquois had a well-established portage route which bypassed the rapids and the cataract later known as Niagara Falls.

In addition to the forts, which also served as authorized agencies for the extensive fur trade, La Salle's visits to Illinois and other Indians cemented the French policy of alliance with Indians in the common causes of containing both Iroquois influence and Anglo-American settlement. He also gave the name Louisiana to the interior North American territory he claimed for France, which lives on in the name of a US state.

1821 Born:  Charles Baudelaire, French poet and critic (d. 1867)

Charles Pierre Baudelaire (9 April 1821 – 31 August 1867) was a French poet who also produced notable work as an essayist, art critic, and pioneering translator of Edgar Allan Poe.

His most famous work, a book of lyric poetry titled Les Fleurs du mal (The Flowers of Evil), expresses the changing nature of beauty in the rapidly industrializing Paris during the mid-19th century. Baudelaire's highly original style of prose-poetry influenced a whole generation of poets including Paul Verlaine, Arthur Rimbaud and Stéphane Mallarmé, among many others. He is credited with coining the term "modernity" (modernité) to designate the fleeting, ephemeral experience of life in an urban metropolis, and the responsibility of artistic expression to capture that experience.

1835 Born: Leopold II of Belgium (d. 1909)

Leopold II (9 April 1835 – 17 December 1909) was King of the Belgians from 1865 to 1909. Born in Brussels as the second but eldest surviving son of Leopold I and Louise of Orléans, he succeeded his father to the Belgian throne in 1865 and reigned for 44 years until his death – the longest reign of any Belgian monarch. He died without surviving male heirs. The current Belgian king descends from his nephew and successor, Albert I.

Leopold was the founder and sole owner of the Congo Free State, a private project undertaken on his own behalf. He used Henry Morton Stanley to help him lay claim to the Congo, the present-day Democratic Republic of the Congo. At the Berlin Conference of 1884–1885, the colonial nations of Europe authorized his claim by committing the Congo Free State to improving the lives of the native inhabitants. Leopold ignored these conditions and ran the Congo using the mercenary Force Publique for his personal gain. He extracted a fortune from the territory, initially by the collection of ivory, and after a rise in the price of rubber in the 1890s, by forced labor from the native population to harvest and process rubber. He used great sums of the money from this exploitation for public and private construction projects in Belgium during this period. He donated the private buildings to the state before his death, to preserve them for Belgium.

Leopold's administration of the Congo was characterized by murder, torture, and atrocities, resulting from notorious systematic brutality. The hands of men, women, and children were amputated when the quota of rubber was not met. These and other facts were established at the time by eyewitness testimony and on site inspection by an international Commission of Inquiry (1904).
Millions of the Congolese people died: modern estimates range from 1 million to 15 million deaths, with a consensus growing around 10 million. Some historians argue against this figure, citing the absence of reliable censuses, the enormous mortality of diseases such as smallpox or sleeping sickness, and the fact that there were only 175 administrative agents in charge of rubber exploitation.

In 1908, the reports of deaths and abuse induced the Belgian government to take over the administration of the Congo from Leopold.

1865 Born: Charles Proteus Steinmetz, Polish-American mathematician and engineer (d. 1923)

Charles Proteus Steinmetz (born Karl August Rudolph Steinmetz, April 9, 1865 – October 26, 1923) was a German-born American mathematician and electrical engineer and professor at Union College. He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers. He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to design better electromagnetic apparatus equipment including especially electric motors for use in industry.

At the time of his death, Steinmetz held over 200 patents. A genius in both mathematics and electronics, he did work that earned him the nicknames "Forger of Thunderbolts" and "The Wizard of Schenectady". Steinmetz's equation, Steinmetz solids, Steinmetz curves, and Steinmetz equivalent circuit theory are all named after him, as are numerous honors and scholarships, including the IEEE Charles Proteus Steinmetz Award, one of the highest technical recognition given by the Institute of Electrical and Electronics Engineers professional society.

1961 Died: Zog I of Albania (b. 1895)

Zog I, King of the Albanians (Albanian: Naltmadhnija e tij Zogu I, Mbreti i Shqiptarëve,  8 October 1895 – 9 April 1961), born Ahmet Muhtar Zogolli, taking the surname Zogu in 1922, was the leader of Albania from 1922 to 1939. He first served as Prime Minister of Albania (1922–1924), then as President (1925–1928), and finally as the first and only King (1928–1939).

Here are some events that happened on April 6th. It could be an event or a person that died or was born on that day


1483 Born: Raphael, Italian painter and architect (d. 1520)

Raffaello Sanzio da Urbino (March 28 or April 6, 1483 – April 6, 1520), known as Raphael, was an Italian painter and architect of the High Renaissance. His work is admired for its clarity of form, ease of composition, and visual achievement of the Neoplatonic ideal of human grandeur. Together with Michelangelo and Leonardo da Vinci, he forms the traditional trinity of great masters of that period.

Raphael was enormously productive, running an unusually large workshop and, despite his early death at 37, leaving a large body of work. Many of his works are found in the Vatican Palace, where the frescoed Raphael Rooms were the central, and the largest, work of his career. The best known work is The School of Athens in the Vatican Stanza della Segnatura. After his early years in Rome, much of his work was executed by his workshop from his drawings, with considerable loss of quality. He was extremely influential in his lifetime, though outside Rome his work was mostly known from his collaborative printmaking.

After his death, the influence of his great rival Michelangelo was more widespread until the 18th and 19th centuries, when Raphael's more serene and harmonious qualities were again regarded as the highest models. His career falls naturally into three phases and three styles, first described by Giorgio Vasari: his early years in Umbria, then a period of about four years (1504–1508) absorbing the artistic traditions of Florence, followed by his last hectic and triumphant twelve years in Rome, working for two Popes and their close associates.

1528 Died: Albrecht Dürer, German painter, engraver, and mathematician (b. 1471)

Albrecht Dürer (21 May 1471 – 6 April 1528), sometimes spelt in English as Durer or Duerer, without umlaut, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe when he was in his twenties due to his high-quality woodcut prints. He was in communication with the major Italian artists of his time, including Raphael, Giovanni Bellini and Leonardo da Vinci, and from 1512 he was patronized by Emperor Maximilian I. Dürer is commemorated by both the Lutheran and Episcopal Churches.

Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts, such as the Apocalypse series (1498), are more Gothic than the rest of his work. His well-known engravings include the Knight, Death and the Devil (1513), Saint Jerome in his Study (1514) and Melencolia I (1514), which has been the subject of extensive analysis and interpretation. His watercolours also mark him as one of the first European landscape artists, while his ambitious woodcuts revolutionized the potential of that medium.

Dürer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective, and ideal proportions.

Albrecht Dürer has been credited with inventing the basic principle of ray tracing, a technique used in modern computer graphics.

1829 Died: Niels Henrik Abel, Norwegian mathematician and theorist (b. 1802)

Niels Henrik Abel (5 August 1802 – 6 April 1829) was a Norwegian mathematician who made pioneering contributions in a variety of fields. His most famous single result is the first complete proof demonstrating the impossibility of solving the general quintic equation in radicals. This question was one of the outstanding open problems of his day, and had been unresolved for over 250 years. He was also an innovator in the field of elliptic functions, discoverer of Abelian functions. He made his discoveries while living in poverty and died at the age of 26 from tuberculosis.

Most of his work was done in six or seven years of his working life. Regarding Abel, the French mathematician Charles Hermite said: "Abel has left mathematicians enough to keep them busy for five hundred years." Another French mathematician, Adrien-Marie Legendre, said: "quelle tête celle du jeune Norvégien!" ("what a head the young Norwegian has!"). 

The Abel Prize in mathematics, originally proposed in 1899 to complement the Nobel Prizes, is named in his honour.

1841 – U.S. President John Tyler is sworn in, two days after having become President upon William Henry Harrison's death.

John Tyler (March 29, 1790 – January 18, 1862) was the tenth president of the United States from 1841 to 1845 after briefly serving as the tenth vice president in 1841; he was elected vice president on the 1840 Whig ticket with President William Henry Harrison. Tyler ascended to the presidency after Harrison's death in April 1841, only a month after the start of the new administration. He was a stalwart supporter and advocate of states' rights, and he adopted nationalist policies as president only when they did not infringe on the powers of the states. His unexpected rise to the presidency posed a threat to the presidential ambitions of Henry Clay and other politicians, and left Tyler estranged from both major political parties.

Tyler was born to a prominent Virginia family and became a national figure at a time of political upheaval. In the 1820s, the nation's only political party was the Democratic-Republican Party, and it split into factions. Tyler was initially a Democrat, but he opposed Andrew Jackson during the Nullification Crisis, seeing Jackson's actions as infringing on states' rights, and he criticized Jackson's expansion of executive power during the Bank War. This led Tyler to ally with the Whig Party. He served as a Virginia state legislator, governor, U.S. representative, and U.S. senator. He was put on the 1840 presidential ticket to attract states' rights Southerners to a Whig coalition to defeat Martin Van Buren's re-election bid.

President Harrison died just one month after taking office, and Tyler became the first vice president to succeed to the presidency without election. He served longer than any president in U.S. history not elected to the office. To forestall constitutional uncertainty, Tyler immediately took the oath of office, moved into the White House, and assumed full presidential powers—a precedent that governed future successions and was codified in the Twenty-fifth Amendment. Tyler signed into law some of the Whig-controlled Congress's bills, but he was a strict constructionist and vetoed the party's bills to create a national bank and raise the tariff rates. He believed that the president should set policy rather than Congress, and he sought to bypass the Whig establishment, most notably senator Henry Clay of Kentucky. Most of Tyler's Cabinet resigned soon into his term, and the Whigs dubbed him His Accidency and expelled him from the party. Tyler was the first president to see his veto of legislation overridden by Congress. He faced a stalemate on domestic policy, although he had several foreign-policy achievements, including the Webster–Ashburton Treaty with Britain and the Treaty of Wanghia with Qing China.

The Republic of Texas separated from Mexico in 1836. Tyler was a firm believer in manifest destiny and saw its annexation as providing an economic advantage to the United States, so he worked diligently to make it happen. He initially sought election to a full term as president, but he failed to gain the support of either Whigs or Democrats and withdrew in support of Democrat James K. Polk, who favored the annexation of Texas. Polk won the election, Tyler signed a bill to annex Texas three days before leaving office, and Polk completed the process. When the American Civil War began in 1861, Tyler sided with the Confederacy and won election to the Confederate House of Representatives shortly before his death. Some scholars have praised Tyler's political resolve, but his presidency is generally held in low regard by historians. He is considered an obscure president, with little presence in American cultural memory.

1890 Born: Anthony Fokker, Dutch engineer and businessman, founded Fokker Aircraft Manufacturer (d. 1939)

Anton Herman Gerard "Anthony" Fokker (6 April 1890 – 23 December 1939) was a Dutch aviation pioneer and aircraft manufacturer. He is most famous for the fighter aircraft he produced in Germany during the First World War such as the Eindecker monoplanes, the Dr.1 triplane and the D.VII biplane.

After the Treaty of Versailles forbade Germany to produce airplanes, Fokker moved his business to the Netherlands. There his company was responsible for a variety of successful aircraft including the Fokker trimotor, a successful passenger aircraft of the inter-war years. He died in New York in 1939. Later authors suggest he was personally charismatic but unscrupulous in business and a controversial character.

1896 – In Athens, the opening of the first modern Olympic Games is celebrated, 1,500 years after the original games are banned by Roman emperor Theodosius I.


The 1896 Summer Olympics (Greek: Θερινοί Ολυμπιακοί Αγώνες 1896, romanized: Therinoí Olympiakoí Agónes 1896), officially known as the Games of the I Olympiad, was the first international Olympic Games held in modern history. Organised by the International Olympic Committee (IOC), which had been created by Pierre de Coubertin, it was held in Athens, Greece, from 6 to 15 April 1896.

Fourteen nations and 241, all male, athletes took part in the games. Participants were all European, or living in Europe, with the exception of the United States team. Winners were given a silver medal, while runners-up received a copper medal. Retroactively, the IOC has converted these to gold and silver, and awarded bronze medals to third placed athletes. Ten of the 14 participating nations earned medals. The United States won the most gold medals, 11, host nation Greece won the most medals overall, 46. The highlight for the Greeks was the marathon victory by their compatriot Spyridon Louis. The most successful competitor was German wrestler and gymnast Carl Schuhmann, who won four events. Over 65% of the competing athletes were Greek.

Athens had been unanimously chosen to stage the inaugural modern Games during a congress organised by Coubertin in Paris on 23 June 1894, during which the IOC was also created, because Greece was the birthplace of the Ancient Olympic Games. The main venue was the Panathenaic Stadium, where athletics and wrestling took place; other venues included the Neo Phaliron Velodrome for cycling, and the Zappeion for fencing. The opening ceremony was held in the Panathenaic Stadium on 6 April, during which most of the competing athletes were aligned on the infield, grouped by nation. After a speech by the president of the organising committee, Crown Prince Constantine, his father officially opened the Games. Afterwards, nine bands and 150 choir singers performed an Olympic Hymn, composed by Spyridon Samaras, with words by poet Kostis Palamas.

The 1896 Olympics were regarded as a great success. The Games had the largest international participation of any sporting event to that date. The Panathenaic Stadium overflowed with the largest crowd ever to watch a sporting event. After the Games, Coubertin and the IOC were petitioned by several prominent figures, including Greece's King George and some of the American competitors in Athens, to hold all the following Games in Athens. However, the 1900 Summer Olympics were already planned for Paris and, except for the Intercalated Games of 1906, the Olympics did not return to Greece until the 2004 Summer Olympics, 108 years later.

2005 Died: Rainier III, Prince of Monaco (b. 1923)

Rainier III (Rainier Louis Henri Maxence Bertrand Grimaldi; 31 May 1923 – 6 April 2005) was the Prince of Monaco from 1949 to his death in 2005. Rainier ruled the Principality of Monaco for almost 56 years, making him one of the longest ruling monarchs in European history. Though internationally known for his marriage to American actress Grace Kelly, he was also responsible for reforms to Monaco's constitution and for expanding the principality's economy from its traditional casino gambling base to its current tax haven role. Gambling accounts for only approximately three per cent of the nation's annual revenue today; when Rainier ascended the throne in 1949, it accounted for more than 95 per cent.
