<human>:  What is the history of the Czech Republic?
<bot>: The Czech Republic has a long and interesting history that dates back to the early Middle Ages. It was first established as the kingdom of Bohemia in the late 9th century when the Přemyslid dynasty rose to power. Modern-day Czech Republic territory was first unified under King Ottokar II of Bohemia in the 13th century. For centuries, the region then became the center of the Holy Roman Empire and a powerful kingdom, with many of its rulers playing an important role in European history. In 1620, the Czech lands were conquered by the Habsburgs and the region was eventually incorporated into the Austrian Empire in 1804. This lasted until the end of World War I, when the Czechs declared independence, creating the modern-day Czechoslovakia. Following World War II, Czechoslovakia was divided into the Czech Republic and Slovakia, both of which have gone on to have amazing success as independent countries.
