The Czech Republic, also known by its short-form name, Czechia, formerly known as Bohemia, is a landlocked country in Central Europe. It is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the east. The Czech Republic has a hilly landscape that covers an area of 78,866 square kilometers with a mostly temperate continental climate and oceanic climate. It is a unitary parliamentary republic.
The Duchy of Bohemia under Great Moravia in 1002 was formally recognized as an Imperial State of the Holy Roman Empire and became a kingdom in 1198. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg Monarchy. The Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of the White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Empire in 1806, the Crown lands became part of the Austrian Empire.
In the 19th century, the Czech lands became more industrialized, and in 1918 most of it became part of the First Czechoslovak Republic following the collapse of Austria-Hungary after World War I.
