Konstantin Päts ( – 18 January 1956) was an Estonian statesman and the country's president in 1938–1940. Päts was one of the most influential politicians of the independent democratic Republic of Estonia, and during the two decades prior to World War II he also served five times as the country's prime minister. After the 16–17 June 1940 Soviet invasion and occupation of Estonia, President Päts remained formally in office for over a month, until he was forced to resign, imprisoned by the new Stalinist regime, and deported to the USSR, where he died in 1956. Päts was one of the first Estonians to become active in politics, and he then started a famous, nearly four decades long, political rivalry with Jaan Tõnisson — first through journalism with his newspaper Teataja, later through politics. Although Päts was sentenced to death (in absentia) during the Russian Revolution of 1905, he was able to flee abroad, first to Switzerland, then to Finland, where he continued his literary work. He returned to Estonia (then part of the Russian Empire), and had to serve a prison sentence in 1910–1911. After the February Revolution in 1917, Päts headed the provincial government of the newly formed Autonomous Governorate of Estonia, which was forced to go underground after the Bolshevik coup in November 1917. On 19 February 1918, Päts became one of the three members of the Estonian Salvation Committee that issued the Estonian Declaration of Independence on 24 February 1918. He headed the Estonian Provisional Government (1918–1919), although he was also imprisoned by the German occupation regime for several months in 1918. In the provisional government, Päts also served as Minister of Internal Affairs (1918) and Minister of War (1918–1919) that left him in charge of organizing the Estonian military in the War of Independence against the Soviet Russian invasion. During the 1920s and early 1930s, Päts led one of the more prominent right-wing parties of the time – the conservative Farmers' Assemblies, which eventually merged into another party, the Union of Settlers and Smallholders in 1932. Päts was the Speaker of the Parliament (Riigikogu) (1922–1923) and served five times as State Elder, a post equivalent to that of president in Estonia's radically parliamentarian system (1921–1922, 1923–1924, 1931–1932, 1932–1933, and 1933–1934). During his last term as State Elder, he organized a self-coup to neutralise the right-wing populist Vaps Movement. He was supported by the army and the
