Coloman of Galicia was the ruler—from 1214 prince, and from 1215 or 1216 to 1221 king—of Halych, and duke of Slavonia from 1226 to his death. He was the second son of Andrew II of Hungary and Gertrude of Merania. His father and Leszek the White, Duke of Poland, concluded an agreement about the marriage of Coloman and Leszek's daughter, Salomea, and the division of Halych, allotting its western regions to Leszek, the remaining lands to Coloman. The Hungarian and Polish armies occupied the principality in late 1214. Andrew II appointed a Hungarian nobleman, Benedict the Bald, to administer it on Coloman's behalf. Coloman was crowned the first king of Halych with the pope's authorization in early 1216.
After the Hungarian troops occupied the western Galician territories, Leszek made an alliance with Mstislav Mstislavich, Prince of Novgorod. Mstislav invaded Halych, forcing Coloman and his supporters to flee to Hungary, most probably in early 1219.
