Milan Rastislav Štefánik in the context of "Tomáš Masaryk"

Tomáš Garrigue Masaryk (7 March 1850 – 14 September 1937) was a Czechoslovak statesman, political activist and philosopher who served as the first president of Czechoslovakia from 1918 to 1935. He is regarded as the founding father of Czechoslovakia.

Born in Hodonín, Moravia (then part of the Austrian Empire), Masaryk obtained a doctorate at the University of Vienna and was a professor of philosophy at the Czech Charles-Ferdinand University. He began his political career as a deputy of the Austrian Reichsrat, serving from 1891 to 1893 and from 1907 to 1914. He was an advocate of restructuring the Austro-Hungarian Empire into a federal state, but by the outbreak of the First World War, he had become a supporter of Czech and Slovak independence. He went into exile, and travelled around Europe to organise and promote the Czechoslovak cause. He played a pivotal role in the establishment of the Czechoslovak Legion, which fought against the Central Powers during the war. In 1918, Masaryk, along with his protégés Edvard Beneš and Milan Rastislav Štefánik, travelled to the United States to obtain support from President Woodrow Wilson and Secretary of State Robert Lansing. Their negotiations resulted in the Washington Declaration, which proclaimed the independence of a Czechoslovak state.

The Czechoslovak Legion (Czech: Československé legie; Slovak: Československé légie) were volunteer armed forces consisting predominantly of Czechs and Slovaks fighting on the side of the Entente powers during World War I and the White Army during the Russian Civil War until November 1919. Their goal was to win the support of the Allied Powers for the independence of the Lands of the Bohemian Crown from the Austrian Empire, and of Upper Hungary from the Kingdom of Hungary, which were then part of the Austro-Hungarian Empire. With the help of émigré intellectuals and politicians such as the Czech Tomáš Garrigue Masaryk and the Slovak Milan Rastislav Štefánik, they grew into a force of over 100,000 troops.

In Russia, they took part in several victorious battles of the war, including the Zborov and Bakhmach against the Central Powers, and were heavily involved in the Russian Civil War fighting Bolsheviks, at times controlling the entire Trans-Siberian railway and several major cities in Siberia.
