George of Kunštát and Poděbrady (23 April 1420 – 22 March 1471), also known as Poděbrad or Podiebrad (Czech: Jiří z Poděbrad; German: Georg von Podiebrad), was King of Bohemia (1458–1471). He was leader of the Hussites. He is known for his idea and attempt to establish common European institutions and supranational insignia. It is seen as first historical vision of European unity.
The Kingdom of Bohemia, sometimes in English literature referred to as the Czech Kingdom (Czech: České království; German: Königreich Böhmen; Latin: Regnum Bohemiae, sometimes Regnum Czechorum), was a medieval and early modern monarchy in Central Europe, the predecessor of the modern Czech Republic. It was an Imperial State in the Holy Roman Empire, and the Bohemian king was a prince-elector of the empire. The kings of Bohemia, besides Bohemia, ruled also the Lands of the Bohemian Crown, which at various times included Moravia, Silesia, Lusatia and parts of Saxony, Brandenburg and Bavaria.
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.
After the dissolution of the Holy Roman Empire in 1806, the territory became part of the Habsburg Austrian Empire, and subsequently the Austro-Hungarian Empire from 1867.
Bohemia is a region in the Czech Republic. In a broader meaning, it often refers to the entire Czech territory, including Moravia and Czech Silesia, especially in historical contexts: the lands of the Bohemian Crown. Bohemia was a kingdom in the Holy Roman Empire and subsequently a province in the Habsburgs’ Austrian Empire. It was bounded on the south by Upper and Lower Austria, on the west by Bavaria, on the north by Saxony and Lusatia, on the northeast by Silesia, and on the east by Moravia. From 1918 to 1939 and from 1945 to 1992 it was part of Czechoslovakia; and, since 1993, it has formed much of the Czech Republic.
