Coloman of Galicia-Lodomeria

Coloman of Galicia (Hungarian: Kálmán, Ukrainian: Коломан) (1208 – 1241) was a member of the Árpád dynasty. He was Prince of Halych (1214–15) and he became the first anointed and crowned King of Galicia–Volhynia (rex Galiciae et Lodomeriae) (1215–19), followed by prince Andrew of Hungary (1219–21). During the second half of his life, he was Duke of Slavonia (1226–41).

Coloman was the second son of Andrew II of Hungary and his first wife, Gertrude of Merania. Andrew was still a child when his father (Coloman's grandfather), Béla III of Hungary, placed him on the throne of the newly conquered Principality of Halych in 1188. His subjects expelled him in 1189 or 1190, because the Hungarian soldiers did not respect the locals' Orthodox faith.

Andrew never abandoned his claim to Halych. After Roman Mstislavich, who had united the principalities of Vladimir-in-Vohynia and Halych under his rule, died fighting the Poles in 1205, Andrew regularly intervened in the conflicts for the rule of the two principalities. He adopted the title of "King of Galicia and Lodomeria" in token of his claim to both principalities before 1208. Initially, Andrew supported Roman Mstislavich's minor sons, Daniel and Vasilko, against Vladimir Igorevich and his brothers, who also claimed Halych.

Meanwhile Coloman's mother vigorously promoted the career of her German kinsmen and courtiers in Hungary, outraging the native lords. Shortly after Andrew departed for a new military campaign against Halych, a group of Hungarian noblemen murdered the queen in September 1213. After learning of his wife's murder, Andrew returned from his campaign, but appointed the Galician boyar Vladislav Kormilichich to lead the Hungarian army to Halych. Kormilichich took control of the principality, but Daniel Romanovich sought assistance from Leszek the White, Duke of Poland. Daniel and Leszek broke into Halych and defeated Kormilichich, but they could not occupy the principality. In retaliation for the Polish attack, Andrew made a raid against Poland, reaching as far as Kraków.
