The Kingdom of Bohemia, sometimes also referred to as the Czech Kingdom, was a state located in the region of Bohemia in Central Europe, whose territory is currently included in the modern-day Czech Republic. During its height, it also had parts of present Austria, Germany, Hungary, Italy, Poland, Slovakia, Slovenia and Ukraine (For Zakarpattia Oblast). It was a kingdom in the Holy Roman Empire, and the King was a Prince-Elector of the empire until its dissolution in 1806. Many Kings of Bohemia were also elected Holy Roman Emperors. Its capital Prague was effectively the centre of the Holy Roman Empire in the late 14th century, and at the end of the 16th and beginning of the 17th centuries. From 1526, the kingdom was continuously ruled by the House of Habsburg and its successor house Habsburg-Lorraine.
After the dissolution of the Holy Roman Empire, the territory became part of the Habsburg's larger Austrian Empire, and subsequently the Austro-Hungarian Empire from 1867. Bohemia retained its name and formal status as a separate Kingdom of Bohemia until 1918, known as a crown land within the Austro-Hungarian Empire, and its capital Prague was one of the empire's leading cities. In the last years of Austria-Hungary, Bohemia was the empire's most advanced and economically prosperous crown land. The Czech language (called the Bohemian language in English usage until the 19th century) was the main language of the Diet and the nobility until 1627 (after the Bohemian Revolt was suppressed). German was then formally made equal with Czech and eventually prevailed as the language of the Diet until the Czech national revival in the 19th century. German was also widely used as the language of administration in many towns after Germans immigrated and populated some areas of the country in the 13th century. The royal court used the Czech, Latin, and German languages, depending on the ruler and period.
