Here are some events that happened on May 18th. It could be an event or a person that died or was born on that day

1711 Born: Roger Joseph Boscovich, Ragusan physicist, astronomer, and mathematician (d. 1787)

Roger Joseph Boscovich (18 May 1711 – 13 February 1787) was a physicist, astronomer, mathematician, philosopher, diplomat, poet, theologian, Jesuit priest, and a polymath from the Republic of Ragusa (modern-day Dubrovnik, Croatia). He studied and lived in Italy and France where he also published many of his works.

Boscovich produced a precursor of atomic theory and made many contributions to astronomy, including the first geometric procedure for determining the equator of a rotating planet from three observations of a surface feature and for computing the orbit of a planet from three observations of its position. In 1753 he also discovered the absence of atmosphere on the Moon.

1804 – Napoleon Bonaparte is proclaimed Emperor of the French by the French Senate.

Napoleon Bonaparte (15 August 1769 – 5 May 1821), born Napoleone di Buonaparte, was a French statesman and military leader who became famous as an artillery commander during the French Revolution. He led many successful campaigns during the French Revolutionary Wars and was Emperor of the French as Napoleon I from 1804 until 1814 and again briefly in 1815 during the Hundred Days. Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions during the Napoleonic Wars. He won many of these wars and a vast majority of his battles, building a large empire that ruled over much of continental Europe before its final collapse in 1815. He is considered one of the greatest commanders in history, and his wars and campaigns are studied at military schools worldwide. Napoleon's political and cultural legacy has made him one of the most celebrated and controversial leaders in human history.  

Napoleon's influence on the modern world brought liberal reforms to the numerous territories that he conquered and controlled, such as the Low Countries, Switzerland, and large parts of modern Italy and Germany. He implemented fundamental liberal policies in France and throughout Western Europe. His Napoleonic Code has influenced the legal systems of more than 70 nations around the world. British historian Andrew Roberts states: "The ideas that underpin our modern world—meritocracy, equality before the law, property rights, religious toleration, modern secular education, sound finances, and so on—were championed, consolidated, codified and geographically extended by Napoleon. To them he added a rational and efficient local administration, an end to rural banditry, the encouragement of science and the arts, the abolition of feudalism and the greatest codification of laws since the fall of the Roman Empire".

1860 – Abraham Lincoln wins the Republican Party presidential nomination over William H. Seward, who later becomes the United States Secretary of State.

Abraham Lincoln (February 12, 1809 – April 15, 1865) was an American statesman and lawyer who served as the 16th president of the United States from March 1861 until his assassination in April 1865. Lincoln led the nation through the American Civil War, its bloodiest war and its greatest moral, constitutional, and political crisis. He preserved the Union, abolished slavery, strengthened the federal government, and modernized the U.S. economy.

Born in Kentucky, Lincoln grew up on the frontier in a poor family. Self-educated, he became a lawyer, Whig Party leader, Illinois state legislator and Congressman. In 1849, he left government to resume his law practice, but angered by the success of Democrats in opening the prairie lands to slavery, reentered politics in 1854. He became a leader in the new Republican Party and gained national attention in 1858 for debating national Democratic leader Stephen A. Douglas in the 1858 Illinois Senate campaign. He then ran for President in 1860, sweeping the North and winning. Southern pro-slavery elements took his win as proof that the North was rejecting the constitutional rights of Southern states to practice slavery. They began the process of seceding from the union. To secure its independence, the new Confederate States of America fired on Fort Sumter, one of the few U.S. forts in the South. Lincoln called up volunteers and militia to suppress the rebellion and restore the Union.

As the leader of the moderate faction of the Republican Party, Lincoln confronted Radical Republicans, who demanded harsher treatment of the South; War Democrats, who rallied a large faction of former opponents into his camp; anti-war Democrats (called Copperheads), who despised him; and irreconcilable secessionists, who plotted his assassination. Lincoln fought the factions by pitting them against each other, by carefully distributing political patronage, and by appealing to the American people. His Gettysburg Address became an iconic call for nationalism, republicanism, equal rights, liberty, and democracy. He suspended habeas corpus, and he averted British intervention by defusing the Trent Affair. Lincoln closely supervised the war effort, including the selection of generals and the naval blockade that shut down the South's trade. As the war progressed, he maneuvered to end slavery, issuing the Emancipation Proclamation of 1863; ordering the Army to protect escaped slaves, encouraging border states to outlaw slavery, and pushing through Congress the Thirteenth Amendment to the United States Constitution, which outlawed slavery across the country.

Lincoln managed his own re-election campaign. He sought to reconcile his damaged nation by avoiding retribution against the secessionists. A few days after the Battle of Appomattox Court House, he was shot by John Wilkes Booth, an actor and Confederate sympathizer, on April 14, 1865, and died the following day. Abraham Lincoln is remembered as the United States' martyr hero. He is consistently ranked both by scholars and the public as among the greatest U.S. presidents.

1868 Born: Nicholas II of Russia (d. 1918)

Nicholas II or Nikolai II Alexandrovich Romanov (18 May  1868 – 17 July 1918), known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer, was the last Tsar of Russia, ruling from 1 November 1894 until his forced abdication on 15 March 1917. His reign saw the fall of the Russian Empire from one of the foremost great powers of the world to economic and military collapse. His memory was reviled by Soviet historians as a weak and incompetent leader whose decisions led to military defeats and the deaths of millions of his subjects. By contrast Anglo-Russian historian Nikolai Tolstoy, leader of the International Monarchist League, says, "There were many bad things about the Tsar's regime, but he inherited an autocracy and his acts are now being seen in perspective and in comparison to the terrible crimes committed by the Soviets."

As Emperor, Nicholas gave limited support to the economic and political reforms promoted by top aides Sergei Witte and Pyotr Stolypin, but they faced too much aristocratic opposition to be fully effective. He supported modernization based on foreign loans and close ties with France, but resisted giving the new parliament (the Duma) major roles. He was criticised for the Khodynka Tragedy, antisemitic pogroms, Bloody Sunday, the violent suppression of the 1905 Russian Revolution, the repression of political opponents, and his perceived responsibility for defeat in the Russo-Japanese War (1904–1905), which saw the annihilation of the Russian Baltic Fleet at the Battle of Tsushima, the loss of Russian influence over Manchuria and Korea, and the Japanese annexation of the north of South Sakhalin Island.

Nicholas signed the Anglo-Russian Entente of 1907, which was designed to counter Germany's attempts to gain influence in the Middle East; it ended the Great Game of confrontation between Russia and the British Empire. He supported Serbia and approved the mobilization of the Russian Army on 30 July 1914. In response, Germany declared war on Russia on 1 August 1914 and its ally France on 3 August 1914, starting the First World War. The aristocracy was alarmed at the powerful influence of the despised peasant priest Grigori Rasputin over the tsar. The severe military losses led to a collapse of morale at the front and at home, leading to the fall of the House of Romanov in the February Revolution of 1917. Nicholas abdicated on behalf of himself and his son. With his family he was imprisoned by the Bolsheviks and executed in July 1918.

1922 Died: Charles Louis Alphonse Laveran, French physician and parasitologist, Nobel Prize laureate (b. 1845)

Charles Louis Alphonse Laveran (18 June 1845 – 18 May 1922) was a French physician who won the Nobel Prize in Physiology or Medicine in 1907 for his discoveries of parasitic protozoans as causative agents of infectious diseases such as malaria and trypanosomiasis. Following his father, Louis Théodore Laveran, he took up military medicine as his profession. He obtained his medical degree from University of Strasbourg in 1867.

At the outbreak of the Franco-Prussian War in 1870, he joined the French Army. At the age of 29 he became Chair of Military Diseases and Epidemics at the École de Val-de-Grâce. At the end of his tenure in 1878 he worked in Algeria, where he made his major achievements. He discovered that the protozoan parasite Plasmodium was responsible for malaria, and that Trypanosoma caused trypanosomiasis or African sleeping sickness. In 1894 he returned to France to serve in various military health services. In 1896 he joined Pasteur Institute as Chief of the Honorary Service, from where he received the Nobel Prize. He donated half of his Nobel prize money to establish the Laboratory of Tropical Medicine at the Pasteur Institute. In 1908, he founded the Société de Pathologie Exotique.

Laveran was elected to French Academy of Sciences in 1893, and was conferred Commander of the National Order of the Legion of Honour in 1912.
