Central Europe is a geographical region of Europe between Eastern, Southern, Western and Northern Europe. Central Europe is known for its cultural diversity; however, countries in this region also share certain historical and cultural similarities.
The region is variously defined but often includes Austria, Croatia, the Czech Republic, Germany, Hungary, Liechtenstein, Lithuania, Poland, Slovakia, Slovenia and Switzerland. Throughout much of the Early Modern period, the territories of Poland and Lithuania were part of the Polish–Lithuanian Commonwealth. Meanwhile, the Ottoman Empire came to occupy most of present-day Croatia and present-day Hungary, and southern parts of present-day Slovakia. The Archduchy of Austria, the Kingdom of Bohemia (Czech Republic), the Duchy of Carniola (part of present-day Slovenia), the various German Principalities and the Old Swiss Confederacy were within the Holy Roman Empire. During the 18th century, the Habsburg monarchy came to reign over the territories of Austria, Croatia, the Czech Republic, Hungary, Slovakia and Slovenia, alongside parts of Serbia, Germany, Italy and Switzerland. Bosnia and Herzegovina, however, was not under Habsburg control during the 18th century; it was occupied in 1878 following the Congress of Berlin and formally annexed in 1908. Between the early 18th and the early 20th centuries, Central Europe had a substantial Jewish population.
