paragraph_text: Kingdom of Bohemia
  
  The Kingdom of Bohemia was a significant regional power during the Middle Ages. In 1212, King Ottokar I (bearing the title "king" since 1198) extracted a Golden Bull of Sicily (a formal edict) from Emperor Frederick II, confirming the royal title for Ottokar and his descendants, and the Duchy of Bohemia was raised to a kingdom. Bohemia's political and financial obligations to the Empire were gradually reduced. Charles IV set Prague to be the seat of the Holy Roman emperor.
