His reign was characterized by permanent internal conflicts: a group of conspirators murdered his queen, Gertrude of Merania (1213); discontent noblemen obliged him to issue the Golden Bull of 1222 establishing their rights (including the right to disobey the king); and he quarreled with his eldest son, Béla who endeavoured to take back the royal domains his father had granted to his followers. King Andrew II, who had been Prince of Halych (1188–1189), intervened regularly in the internal struggles of the principality and made several efforts to ensure the rule of his younger sons (Coloman or Andrew) in the neighboring country. One of his daughters, Elizabeth was canonized during his lifetime (1 July 1235) and thus became the fourth saint of the Árpáds. King Andrew's elder sons disowned his posthumous son, Stephen, who would be educated in Ferrara.
