The Czech Republic Czech: Česká republika, pronounced [ˈtʃɛskaː ˈrɛpuˌblɪka] ( listen), short form Česko Czech pronunciation: [ˈtʃɛskɔ]) is a landlocked country in Central Europe. The country is bordered by Poland to the north, Germany to the west, Austria to the south and Slovakia to the east. Its capital and largest city, with 1.3 million inhabitants, is Prague. It is a pluralist multi-party parliamentary representative democracy, a member of the European Union, NATO, the OECD, the OSCE, the Council of Europe and the Visegrád Group. The Czech state, formerly known as Bohemia, was formed in the late 9th century as a small duchy around Prague, at that time under dominance of the powerful Great Moravian Empire (which reached its greatest territorial extent during the reign of Svatopluk I from the House of Mojmír). After the fall of the Empire in 907, the centre of power was transferred from Moravia to Bohemia, under the Přemyslids. During the rule of Přemyslid dukes/kings and their successors, the Luxembourgs, the country reached its greatest territorial extent (13th–14th century). Life in the country was significantly affected by the Hussite wars, during which it faced economic embargo and crusades from all over Europe. Following the Battle of Mohács in 1526, the Crown of Bohemia was gradually integrated into the Habsburg monarchy as one of its three principal parts alongside the Archduchy of Austria and the Kingdom of Hungary. The Bohemian Revolt (1618–20) led to the further centralisation of the monarchy including forced recatholization and Germanisation. During radical reforms in the 18th century the Bohemian Crown was even de facto abolished (1749). In the 19th century the Czech lands became the industrial powerhouse of the monarchy and the core of the Republic of Czechoslovakia which was formed in 1918, following the collapse of the Austro-Hungarian empire after World War I.
