Jaroslav Hašek was a Czech writer, humorist, satirist, journalist, bohemian, first anarchist and then communist, and commissar of the Red Army against the Czechoslovak Legion. He is best known for his novel The Fate of the Good Soldier Švejk during the World War, an unfinished collection of farcical incidents about a soldier in World War I and a satire on the ineptitude of authority figures. The novel has been translated into about 60 languages, making it the most translated novel in Czech literature.

The Czechoslovak Legion were volunteer armed forces comprised 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 Lands of the Bohemian Crown from the Austrian Empire and of Slovak territories 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 over 100,000 strong.
