The Czech state or Bohemia was formed in the late 9th century. The country reached its greatest territorial extent during the 13th and 14th century under the rule of the Přemyslid and Luxembourg dynasties. Following the Battle of Mohács in 1526, the Kingdom of Bohemia was integrated into the Habsburg monarchy as one of its three principal parts alongside Austria and Hungary. Despite being named as Bohemia, the country also has great part of the region of Moravia.
