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).

1492 Died: Lorenzo de' Medici, Italian ruler (b. 1449)

Lorenzo de' Medici (1 January 1449 – 8 April 1492) was an Italian statesman, de facto ruler of the Florentine Republic and the most powerful and enthusiastic patron of Renaissance culture in Italy. Also known as Lorenzo the Magnificent (Lorenzo il Magnifico) by contemporary Florentines, he was a magnate, diplomat, politician and patron of scholars, artists and poets. As a patron, he is best known for his sponsorship of artists such as Botticelli and Michelangelo. He held the balance of power within the Italic League, an alliance of states that stabilized political conditions on the Italian peninsula for decades, and his life coincided with the mature phase of the Italian Renaissance and the Golden Age of Florence. The Peace of Lodi of 1454 that he helped maintain among the various Italian states collapsed with his death. He is buried in the Medici Chapel in Florence.

1818 Born:  Christian IX of Denmark (d. 1906)

Christian IX (8 April 1818 – 29 January 1906) was King of Denmark from 1863 until his death in 1906. From 1863 to 1864, he was concurrently Duke of Schleswig, Holstein and Lauenburg.

Growing up as a prince of Schleswig-Holstein-Sonderburg-Glücksburg, a junior branch of the House of Oldenburg which had ruled Denmark since 1448, Christian was originally not in the immediate line of succession to the Danish throne. However, in 1852, Christian was chosen as heir to the Danish monarchy in light of the expected extinction of the senior line of the House of Oldenburg. Upon the death of King Frederick VII of Denmark in 1863, Christian (who was both Frederick's uncle and cousin) acceded to the throne as the first Danish monarch of the House of Glücksburg.

The beginning of his reign was marked by the Danish defeat in the Second Schleswig War and the subsequent loss of the duchies of Schleswig, Holstein and Lauenburg which made the king immensely unpopular. The following years of his reign were dominated by political disputes as Denmark had only become a constitutional monarchy in 1849 and the balance of power between the sovereign and parliament was still in dispute. In spite of his initial unpopularity and the many years of political strife, where the king was in conflict with large parts of the population, his popularity recovered towards the end of his reign, and he became a national icon due to the length of his reign and the high standards of personal morality with which he was identified.

Christian married his second cousin, Princess Louise of Hesse-Kassel, in 1842. Their six children married into other royal families across Europe, earning him the sobriquet "the father-in-law of Europe". Among his descendants are Margrethe II of Denmark, Elizabeth II of the United Kingdom, Philippe of Belgium, Harald V of Norway, Felipe VI of Spain, Grand Duke Henri of Luxembourg, Constantine II of Greece, Queen Anne-Marie of Greece, Queen Sofia of Spain and Prince Philip, Duke of Edinburgh

1835 Died: Wilhelm von Humboldt, German philosopher, academic, and politician, Interior Minister of Prussia (b. 1767 )

Friedrich Wilhelm Christian Karl Ferdinand von Humboldt (22 June 1767 – 8 April 1835) was a Prussian philosopher, linguist, government functionary, diplomat, and founder of the Humboldt University of Berlin, which was named after him in 1949 (and also after his younger brother, Alexander von Humboldt, a naturalist).

He is especially remembered as a linguist who made important contributions to the philosophy of language, ethnolinguistics and to the theory and practice of education. He made a major contribution to the development of liberalism by envisioning education as a means of realizing individual possibility rather than a way of drilling traditional ideas into youth to suit them for an already established occupation or social role. In particular, he was the architect of the Humboldtian education ideal, which was used from the beginning in Prussia as a model for its system of public education, as well as in the United States and Japan. He was elected as a member of the American Philosophical Society in 1822.

1875 Born: Albert I of Belgium (d. 1934)

Albert I (8 April 1875 – 17 February 1934) reigned as King of the Belgians from 1909 to 1934. This was an eventful period in the history of Belgium, which included the period of World War I (1914–1918), when 90 percent of Belgium was overrun, occupied, and ruled by the German Empire. Other crucial issues included the adoption of the Treaty of Versailles, the ruling of the Belgian Congo as an overseas possession of the Kingdom of Belgium along with the League of Nations mandate of Ruanda-Urundi, the reconstruction of Belgium following the war, and the first five years of the Great Depression (1929–1934). King Albert died in a mountaineering accident in eastern Belgium in 1934, at the age of 58, and he was succeeded by his son Leopold III (r. 1934–1951).

1973 Died: Pablo Picasso, Spanish painter and sculptor (b. 1881)

Pablo Ruiz Picasso (25 October 1881 – 8 April 1973) was a Spanish painter, sculptor, printmaker, ceramicist, stage designer, poet and playwright who spent most of his adult life in France. Regarded as one of the most influential artists of the 20th century, he is known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage, and for the wide variety of styles that he helped develop and explore. Among his most famous works are the proto-Cubist Les Demoiselles d'Avignon (1907), and Guernica (1937), a dramatic portrayal of the bombing of Guernica by the German and Italian airforces during the Spanish Civil War.

Picasso demonstrated extraordinary artistic talent in his early years, painting in a naturalistic manner through his childhood and adolescence. During the first decade of the 20th century, his style changed as he experimented with different theories, techniques, and ideas. After 1906, the Fauvist work of the slightly older artist Henri Matisse motivated Picasso to explore more radical styles, beginning a fruitful rivalry between the two artists, who subsequently were often paired by critics as the leaders of modern art.

Picasso's work is often categorized into periods. While the names of many of his later periods are debated, the most commonly accepted periods in his work are the Blue Period (1901–1904), the Rose Period (1904–1906), the African-influenced Period (1907–1909), Analytic Cubism (1909–1912), and Synthetic Cubism (1912–1919), also referred to as the Crystal period. Much of Picasso's work of the late 1910s and early 1920s is in a neoclassical style, and his work in the mid-1920s often has characteristics of Surrealism. His later work often combines elements of his earlier styles.

Exceptionally prolific throughout the course of his long life, Picasso achieved universal renown and immense fortune for his revolutionary artistic accomplishments, and became one of the best-known figures in 20th-century art.

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


1454 Born: Amerigo Vespucci, Italian cartographer and explorer (d. 1512)

Amerigo Vespucci (March 9, 1454 – February 22, 1512) was an Italian explorer, financier, navigator, and cartographer from the Republic of Florence. Sailing for Portugal around 1501–1502, Vespucci demonstrated that Brazil and the West Indies were not Asia's eastern outskirts (as initially conjectured from Columbus' voyages) but a separate continent described as the "New World". In 1507, the new continent was named America after the Latin version of Vespucci's first name.  Vespucci then became a citizen of the Crown of Castile and died in Seville (1512).

1851 Died: Hans Christian Ørsted, Danish physicist and chemist (b. 1777)

Hans Christian Ørsted (often rendered Oersted in English; 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. Oersted's law and the oersted (Oe) are named after him.

On 21 April 1820, Ørsted published his discovery that a compass needle was deflected from magnetic north by a nearby electric current, confirming a direct relationship between electricity and magnetism. The often reported story that Ørsted made this discovery incidentally during a lecture is a myth. He had, in fact, been looking for a connection between electricity and magnetism since 1818, but was quite confused by the results he was obtaining. 

His initial interpretation was that magnetic effects radiate from all sides of a wire carrying an electric current, as do light and heat. Three months later, he began more intensive investigations and soon thereafter published his findings, showing that an electric current produces a circular magnetic field as it flows through a wire.  For his discovery, the Royal Society of London awarded Ørsted the Copley Medal in 1820 and the French Academy granted him 3,000 francs.

Ørsted's findings stirred much research into electrodynamics throughout the scientific community, influencing French physicist André-Marie Ampère's developments of a single mathematical formula to represent the magnetic forces between current-carrying conductors. Ørsted's work also represented a major step toward a unified concept of energy.

A leader of the Danish Golden Age, Ørsted was a close friend of Hans Christian Andersen and the brother of politician and jurist Anders Sandøe Ørsted, who served as Prime Minister of Denmark from 1853 to 1854.

2011 – Space Shuttle Discovery makes its final landing after 39 flights.

Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, gathering more spaceflights than any other spacecraft to date. Like other shuttles, the shuttle has three main components: the Space Shuttle orbiter, a central fuel tank, and two rocket boosters. Nearly 25,000 heat resistant tiles cover the orbiter to protect it from high temperatures on re-entry.

Discovery became the third operational orbiter to enter service, preceded by Columbia and Challenger. It embarked on its last mission, STS-133, on February 24, 2011 and touched down for the final time at Kennedy Space Center on March 9

The mission launched at 4:53 pm EST on February 24, was carrying the Permanent Multipurpose Module (PMM) Leonardo, the ELC-4 and Robonaut 2 to the ISS. Final flight of Discovery.

Discovery was decommissioned on March 9, 2011.

Here are some events that happened on March 5th. It could be an event or a person that died or was born on that day


1512 Born: Gerardus Mercator, Flemish mathematician, cartographer, and philosopher (d. 1594)

Gerardus Mercator (5 March 1512 – 2 December 1594) was a 16th-century geographer, cosmographer and cartographer from the County of Flanders. He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing (rhumb lines) as straight lines—an innovation that is still employed in nautical charts.

Mercator was one of the pioneers of cartography and is widely considered the most notable figure of the school in its golden age (approximately 1570s–1670s). In his own day, he was a notable as maker of globes and scientific instruments. In addition, he had interests in theology, philosophy, history, mathematics and geomagnetism. He was also an accomplished engraver and calligrapher. Unlike other great scholars of the age he travelled little and his knowledge of geography came from his library of over one thousand books and maps, from his visitors and from his vast correspondence (in six languages) with other scholars, statesmen, travellers, merchants and seamen. Mercator's early maps were in large formats suitable for wall mounting but in the second half of his life, he produced over 100 new regional maps in a smaller format suitable for binding into his Atlas of 1595. This was the first appearance of the word Atlas in reference to a book of maps. However, Mercator used it as a neologism for a treatise (Cosmologia) on the creation, history and description of the universe, not simply a collection of maps. He chose the word as a commemoration of the Titan Atlas, "King of Mauretania", whom he considered to be the first great geographer.

A large part of Mercator's income came from sales of his terrestrial and celestial globes. For sixty years they were considered the finest in the world, and were sold in such great numbers that there are many surviving examples. This was a substantial enterprise involving the manufacture of the spheres, printing the gores, building substantial stands, packing and distributing all over Europe. He was also renowned for his scientific instruments, particularly his astrolabes and astronomical rings used to study the geometry of astronomy and astrology.

Mercator wrote on geography, philosophy, chronology and theology. All of the wall maps were engraved with copious text on the region concerned. As an example the famous world map of 1569 is inscribed with over five thousand words in fifteen legends. The 1595 Atlas has about 120 pages of maps and illustrated title pages but a greater number of pages are devoted to his account of the creation of the universe and descriptions of all the countries portrayed. His table of chronology ran to some 400 pages fixing the dates (from the time of creation) of earthly dynasties, major political and military events, volcanic eruptions, earthquakes and eclipses. He also wrote on the gospels and the old testament.

Mercator was a devout Christian born into a Catholic family at a time when Martin Luther's Protestantism was gaining ground. He never declared himself as a Lutheran but he was clearly sympathetic and he was accused of heresy by Catholic authorities; after six months in prison he was released unscathed. This period of persecution is probably the major factor in his move from Catholic Leuven (Louvain) to a more tolerant Duisburg, in the Holy Roman Empire, where he lived for the last thirty years of his life. Walter Ghim, Mercator's friend and first biographer, describes him as sober in his behaviour, yet cheerful and witty in company, and never more happy than in debate with other scholars. Above all he was pious and studious until his dying days.

1827 Died: Pierre-Simon Laplace, French mathematician and astronomer (b. 1749)

Pierre-Simon, marquis de Laplace (23 March 1749 – 5 March 1827) was a French scholar and polymath whose work was important to the development of engineering, mathematics, statistics, physics, astronomy, and philosophy. He summarized and extended the work of his predecessors in his five-volume Mécanique Céleste (Celestial Mechanics) (1799–1825). This work translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems. In statistics, the Bayesian interpretation of probability was developed mainly by Laplace.

Laplace formulated Laplace's equation, and pioneered the Laplace transform which appears in many branches of mathematical physics, a field that he took a leading role in forming. The Laplacian differential operator, widely used in mathematics, is also named after him. He restated and developed the nebular hypothesis of the origin of the Solar System and was one of the first scientists to postulate the existence of black holes and the notion of gravitational collapse.

Laplace is remembered as one of the greatest scientists of all time. Sometimes referred to as the French Newton or Newton of France, he has been described as possessing a phenomenal natural mathematical faculty superior to that of any of his contemporaries. He was Napoleon's examiner when Napoleon attended the École Militaire in Paris in 1784. Laplace became a count of the Empire in 1806 and was named a marquis in 1817, after the Bourbon Restoration.

1827 Died: Alessandro Volta, Italian physicist and academic (b. 1745)

Alessandro Giuseppe Antonio Anastasio Volta (18 February 1745 – 5 March 1827) was an Italian physicist, chemist, and pioneer of electricity and power who is credited as the inventor of the electric battery and the discoverer of methane. He invented the Voltaic pile in 1799, and reported the results of his experiments in 1800 in a two-part letter to the President of the Royal Society. With this invention Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings. Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments which eventually led to the development of the field of electrochemistry.

Volta also drew admiration from Napoleon Bonaparte for his invention, and was invited to the Institute of France to demonstrate his invention to the members of the Institute. Volta enjoyed a certain amount of closeness with the emperor throughout his life and he was conferred numerous honors by him. Volta held the chair of experimental physics at the University of Pavia for nearly 40 years and was widely idolized by his students.

Despite his professional success, Volta tended to be a person inclined towards domestic life and this was more apparent in his later years. At this time he tended to live secluded from public life and more for the sake of his family until his eventual death in 1827 from a series of illnesses which began in 1823. The SI unit of electric potential is named in his honor as the volt.

1871 Born: Rosa Luxemburg, Polish-Russian economist and philosopher (d. 1919)

Rosa Luxemburg (5 March 1871 – 15 January 1919) was a Polish Marxist, philosopher, economist, anti-war activist and revolutionary socialist who became a naturalized German citizen at the age of 28. Successively, she was a member of the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), the Social Democratic Party of Germany (SPD), the Independent Social Democratic Party (USPD) and the Communist Party of Germany (KPD).

After the SPD supported German involvement in World War I in 1915, Luxemburg and Karl Liebknecht co-founded the anti-war Spartacus League (Spartakusbund) which eventually became the KPD. During the November Revolution, she co-founded the newspaper Die Rote Fahne (The Red Flag), the central organ of the Spartacist movement. Luxemburg considered the Spartacist uprising of January 1919 a blunder, but supported the attempted overthrow of the government and rejected any attempt at a negotiated solution. Friedrich Ebert's majority SPD government crushed the revolt and the Spartakusbund by sending in the Freikorps, government-sponsored paramilitary groups consisting mostly of World War I veterans. Freikorps troops captured and summarily executed Luxemburg and Liebknecht during the rebellion. Luxemburg's body was thrown in the Landwehr Canal in Berlin.

Due to her pointed criticism of both the Leninist and the more moderate social democratic schools of socialism, Luxemburg has had a somewhat ambivalent reception among scholars and theorists of the political left. Nonetheless, Luxemburg and Liebknecht were extensively idolized as communist martyrs by the East German communist regime. The German Federal Office for the Protection of the Constitution notes that idolization of Luxemburg and Liebknecht is an important tradition of German far-left extremism.

1953 – Joseph Stalin, the longest serving leader of the Soviet Union, dies at his Volynskoe dacha in Moscow after suffering a cerebral hemorrhage 4 days earlier.

Joseph Vissarionovich Stalin (18 December 1878 – 5 March 1953) was a Georgian revolutionary and Soviet politician who led the Soviet Union from the mid–1920s until 1953 as the general secretary of the Communist Party of the Soviet Union (1922–1952) and premier of the Soviet Union (1941–1953). Despite initially governing the Soviet Union as part of a collective leadership, he eventually consolidated power to become the country's de facto dictator by the 1930s. A communist ideologically committed to the Leninist interpretation of Marxism, Stalin formalised these ideas as Marxism–Leninism, while his own policies are known as Stalinism.

Born to a poor family in Gori in the Russian Empire (now Georgia), Stalin joined the Marxist Russian Social Democratic Labour Party as a youth. He edited the party's newspaper, Pravda, and raised funds for Vladimir Lenin's Bolshevik faction via robberies, kidnappings, and protection rackets. Repeatedly arrested, he underwent several internal exiles. After the Bolsheviks seized power during the 1917 October Revolution and created a one-party state under Lenin's newly renamed Communist Party, Stalin joined its governing Politburo. Serving in the Russian Civil War before overseeing the Soviet Union's establishment in 1922, Stalin assumed leadership over the country following Lenin's 1924 death. Under Stalin, "Socialism in One Country" became a central tenet of the party's dogma. Through the Five-Year Plans, the country underwent agricultural collectivisation and rapid industrialisation, creating a centralised command economy. This led to significant disruptions in food production that contributed to the famine of 1932–33. To eradicate accused "enemies of the working class", Stalin instituted the "Great Purge", in which over a million were imprisoned and at least 700,000 executed between 1934 and 1939. By 1937, he had complete personal control over the party and state.

Stalin's government promoted Marxism–Leninism abroad through the Communist International and supported European anti-fascist movements during the 1930s, particularly in the Spanish Civil War. In 1939, it signed a non-aggression pact with Nazi Germany, resulting in the Soviet invasion of Poland. Germany ended the pact by invading the Soviet Union in 1941. Despite initial setbacks, the Soviet Red Army repelled the German incursion and captured Berlin in 1945, ending World War II in Europe. The Soviets annexed the Baltic states and helped establish Soviet-aligned governments throughout Central and Eastern Europe, China, and North Korea. The Soviet Union and the United States emerged from the war as global superpowers. Tensions arose between the Soviet-backed Eastern Bloc and U.S.-backed Western Bloc which became known as the Cold War. Stalin led his country through the post-war reconstruction, during which it developed a nuclear weapon in 1949. In these years, the country experienced another major famine and an anti-semitic campaign peaking in the doctors' plot. After Stalin's death in 1953 he was eventually succeeded by Nikita Khrushchev, who denounced his predecessor and initiated the de-Stalinisation of Soviet society.

Widely considered one of the 20th century's most significant figures, Stalin was the subject of a pervasive personality cult within the international Marxist–Leninist movement which revered him as a champion of the working class and socialism. Since the dissolution of the Soviet Union in 1991, Stalin has retained popularity in Russia and Georgia as a victorious wartime leader who established the Soviet Union as a major world power. Conversely, his totalitarian government has been widely condemned for overseeing mass repressions, ethnic cleansing, deportations, hundreds of thousands of executions, and famines which killed millions.
