Coloman was born in 1208. According to historians Márta Font and Gábor Barabás, he was named most probably for Coloman of Stockerau, an Irish pilgrim who had been martyred in Austria in 1012. Coloman's mother showed blatant favoritism towards her German kinsmen and courtiers, which outraged the native lords. She was murdered by a group of Hungarian noblemen in September 1213, shortly after her husband departed for a new military campaign against Halych. Andrew returned to Hungary, but only after appointing a Galician "boyar" (or nobleman), Vladislav Kormilichich, to lead the Hungarian army to Halych. Kormilichich took control of the principality on Andrew's behalf. Leszek the White, Duke of Poland, granted asylum to Daniel and Vasilko Romanovich and made an alliance with princes Alexandr Vsevolodovich of Vladimir and Mstislav Yaroslavich of Peresopnytsia. They invaded Halych and routed Kormilichich, but they could not capture the capital of the principality.
