It was an Imperial State in the Holy Roman Empire, and the Bohemian king was a prince-elector of the empire. The Czech king besides Bohemia ruled also the Lands of the Bohemian Crown. The capital of the kingdom, Prague, was also the imperial seat in periods between the 14th and 17th century.
The kingdom was established by the Přemyslid dynasty in the 12th century from Duchy of Bohemia, later ruled by the House of Luxembourg, the Jagiellonian dynasty, and since 1526 by the House of Habsburg and its successor house Habsburg-Lorraine. Numerous kings of Bohemia were also elected Holy Roman Emperors and the capital Prague was the imperial seat in the late 14th century, and at the end of the 16th and beginning of the 17th centuries.
