Andrew II of Hungary was a king who ruled from 1205 to 1235. He was a member of the Árpád dynasty and is known for his efforts to strengthen the kingdom and expand its territories. His reign was marked by conflicts with the nobility and challenges in maintaining control over his lands. During his rule, Andrew II issued the Golden Bull of 1222, which limited royal power and established certain rights for the nobility. This document is considered a significant step towards the development of constitutional governance in Hungary. Andrew's reign ultimately faced difficulties, leading to a decline in royal authority.
