Page "Holy Roman Empire" Paragraph 25

The Kingdom of Bohemia was, as the only kingdom in the empire, a significant regional power during the Middle Ages.

In 1212, King Přemysl Otakar I ( bearing the title " king " since 1198 ) extracted a Golden Bull of Sicily ( a formal edict ) from the emperor Frederick II., confirming the royal title for Otakar and his descendants and the Duchy of Bohemia was raised to a kingdom.

Czech king should be exempt from all future obligations to the Holy Roman Empire except for participation in the imperial councils.
