Slovakia

The Slavs began to settle in the territory of present-day Slovakia.

The Slavs established the Principality of Nitra after the dissolution of the Avar Khaghanate.

The territory was integrated into the Kingdom of Hungary under the Hungarian crown.

The Hungarian declaration of independence prompted the Slovak Uprising and the formation of the Slovak National Council.

The state of Czechoslovakia was proclaimed after World War I during the collapse of the Austro-Hungarian Empire.

The first Slovak Republic was founded as a fascist client state under Nazi Germany.

Czechoslovakia was re-established after the country's liberation at the end of World War II.

The Prague Spring represented attempts to liberalize communism, suppressed by a Warsaw Pact invasion.

The Velvet Revolution peacefully ended Communist rule in Czechoslovakia.

Slovakia became an independent democratic state following the peaceful dissolution of Czechoslovakia.
