Konstantin Päts, Estonian journalist, lawyer, and politician, 1st President of Estonia (b. 1874)
Konstantin Päts (Estonian pronunciation: [ˈkons.tɑnʲ.tin ˈpætʲs]; 23 February [O.S. 11 February] 1874 – 18 January 1956) was an Estonian politician. He was one of the most influential politicians of interwar Estonia, and served five times as the country's head of government. He was one of the first Estonians to become active in politics and started an almost 40-year political rivalry with Jaan Tõnisson, first through journalism with his newspaper Teataja, later through politics. He was condemned to death during the 1905 Revolution, but managed to flee first to Switzerland, then to Finland, where he continued his literary work. He returned to Estonia, but had to spend time in prison in 1910–1911.

In 1917, Päts headed the provincial government of the Autonomous Governorate of Estonia, but was forced to go underground after the October Revolution. 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. Konstantin Päts headed the Estonian Provisional Government (1918–1919), although he was imprisoned during the second half of the German Occupation. In the provisional government, Päts also served as Minister of Internal Affairs (1918) and Minister of War (1918–1919) that left him organizing Estonian troops for the War of Independence.

During the 1920s and early 1930s, Päts led the most right-wing party of the major political parties of the time – the conservative Farmers' Assemblies that eventually merged with the Union of Settlers and Smallholders in 1932. Päts was the speaker of the 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 parliament. During the authoritarian regime ("Era of Silence"), many reforms were made and the economy grew, while he prolonged the return of constitutional order. Largely supported by General Johan Laidoner, Commander of the Estonian Defence Forces, Päts ruled as Prime Minister in duties of the State Elder (1934–1937) and President-Regent (1937–1938) until a new constitution was adopted in 1938, after which Päts became the first President of Estonia. During his presidency, the Soviet Union occupied Estonia in 1940. As President, he was forced to sign decrees for over a month, until he was finally arrested and deported to the Soviet Union, where he died in 1956.
