1566 – 1839Wars & Stagnation (1566–1839)The period from Suleiman's death to the Tanzimat reforms spans 273 years of gradual but accelerating decline punctuated by moments of recovery. The failed siege of Vienna (1683) marks the definitive end of Ottoman expansion in Europe; the Treaty of Karlowitz (1699) begins the long territorial retreat. Russia emerges as the empire's most dangerous enemy, fighting six wars and pushing the Ottoman frontier steadily south. The Janissaries -- once the empire's elite force -- become a conservative political force that murders reforming sultans. The empire earns its 19th-century epithet: 'the sick man of Europe.'
1838 – 1839Schleiden and Schwann — cell theoryAll living things are made of cellsIn 1838-1839, Matthias Schleiden (plants) and Theodor Schwann (animals) independently proposed that all living organisms are composed of cells and that the cell is the fundamental unit of life. Virchow added in 1855 that all cells come from pre-existing cells. Cell theory is one of the three pillars of modern biology alongside evolution and genetics.
1839 – 1899Alfred Sisley (1839-1899)Died 29 January 1899, aged 59British-born painter and leading figure of French Impressionism, known for landscapes along the Seine and Loing rivers.

1839 – 1914Carol I of Romania (1839-1914)Died 10 October 1914, aged 75A German prince installed as ruler of Romania in 1866, Carol I became the country's first king in 1881 and oversaw its modernization and independence from Ottoman suzerainty. His nearly five-decade reign was the longest in Romanian history. He died weeks into the war, having clashed with his government over Romania's neutrality.
1839 – 1914Charles Sanders Peirce (1839-1914)Died 19 April 1914, aged 74An American philosopher, logician, and scientist, Peirce founded the philosophical school of pragmatism and made lasting contributions to semiotics and logic. He worked much of his life in poverty and obscurity, gaining wider recognition only after his death. He is now regarded as one of America's most original thinkers.
1839 – 1842First Opium WarBritain forces China to open — the century of humiliation beginsBritain went to war with China to force it to continue accepting opium imports from British India, which China had banned. The technologically superior British fleet defeated China decisively. The 1842 Treaty of Nanking ceded Hong Kong to Britain, opened five treaty ports, and paid a massive indemnity. It was the first of the "unequal treaties" that humiliated China and began what Chinese call the "century of humiliation" lasting until 1949.
1839 – 1876George Armstrong Custer (1839-1876)Died 25 June 1876, aged 36George Armstrong Custer was a US Army officer who rose to fame as a cavalry commander in the Civil War. He was killed with his command at the Battle of the Little Bighorn on June 25, 1876.
1839 – 1922Reform & Collapse (1839–1922)The final 83 years of Ottoman history are the most dramatic -- a race between modernisation and disintegration that the empire ultimately loses. The Tanzimat reforms (1839-1876) attempt to create a modern centralised state with equal rights for all subjects. The Constitutional period (1876, 1908) produces two parliaments. But the Balkan Wars (1912-1913) strip the empire of nearly all its European territory; the First World War (1914-1918) destroys it; the Armenian Genocide (1915-1923) kills over a million people; and Ataturk's War of Independence (1919-1922) produces the Turkish Republic from the ruins. The sultanate is abolished on 1 November 1922.
