Overview
Founded on 28 October 1918 from the Czech lands and Slovakia of the collapsing Habsburg empire, the First Czechoslovak Republic under Tomáš Garrigue Masaryk and Edvard Beneš was interwar Central Europe's most durable democracy, though strained by its large German (Sudeten), Hungarian and Ruthenian minorities. The Munich Agreement (September 1938), by which Britain, France, Italy and Germany forced the cession of the Sudetenland without Czechoslovak participation ("about us, without us"), fatally crippled it. In March 1939 Germany occupied the Czech lands as the Protectorate of Bohemia and Moravia, while a clerical-fascist Slovak Republic (1939–1945) under Jozef Tiso became a nominally independent Axis client that deported most of its Jews.
Decline and legacy
Restored in 1945 (with the expulsion of some 3 million Sudeten Germans and the cession of Ruthenia to the USSR), Czechoslovakia fell to a communist coup in February 1948, becoming a Stalinist one-party state (from 1960 the Czechoslovak Socialist Republic, ČSSR). The reformist Prague Spring of 1968 ("socialism with a human face" under Alexander Dubček) was crushed by a Warsaw Pact invasion in August 1968, followed by two decades of "normalisation." The Velvet Revolution of November 1989 peacefully ended communist rule, elevating the dissident playwright Václav Havel to the presidency. Rising Czech–Slovak tensions led to the negotiated "Velvet Divorce," and on 1 January 1993 the federation split amicably into the Czech Republic and Slovakia.
