History of Slovakia
In 1918, Slovakia and the regions of Bohemia and Moravia formed a common state, Czechoslovakia, with the borders confirmed by the Treaty of Saint Germain and Treaty of Trianon. In 1919, during the chaos following the breakup of Austria-Hungary, Czechoslovakia was formed with numerous Germans and Hungarians within the newly set borders. A Slovak patriot Milan Rastislav Štefánik (1880–1919), who helped organize Czechoslovak regiments against Austria-Hungary during the First World War, died in a plane crash during the fighting. In the peace following the World War, Czechoslovakia emerged as a sovereign European nation.
During the Interwar period, democratic Czechoslovakia was allied with France, and also with Romania and Yugoslavia (Little Entente); however, the Locarno Treaties of 1925 left East European security open. Both Czechs and Slovaks enjoyed a period of relative prosperity. Not only was there progress in the development of the country's economy, but in culture and in educational opportunities as well. The minority Germans came to accept their role in the new country and relations with Austria were good. Yet the Great Depression caused a sharp economic downturn, followed by political disruption and insecurity in Europe.
Thereafter Czechoslovakia came under continuous pressure from the revisionist governments of Germany and Hungary. Eventually this led to the Munich Agreement of September 1938, which allowed Nazi Germany to partially dismember the country by occupying what was called the Sudetenland, a region with a German-speaking majority and bordering Germany and Austria. The remainder of "rump" Czechoslovakia was renamed Czecho-Slovakia and included a greater degree of Slovak political autonomy. Southern and eastern Slovakia, however, was claimed back by Hungary at the First Vienna Award of November 1938.
