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 Pr(emyslids. During the rule of Pr(emyslid dukes/kings and their successors, the Luxembourgs, the country reached its greatest territorial extent (13th–14th century). Life in the country was very 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 end of state independence for 300 years, domination of the Habsburgs and subsequent forced recatholization and Germanization. During radical reforms in 18th century the Bohemian Crown was even de facto abolished (1749). In 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.
