Галицкое княжество
Andrew was the second son of King Béla III and Béla's first wife, Agnes of Antioch. The year of Andrew's birth is not known, but modern historians agree that he was born around 1177. Andrew was first mentioned in connection to his father's invasion of the Principality of Halych in 1188. That year, Béla III invaded Halych upon the request of its former prince, Vladimir II Yaroslavich, who had been expelled by his subjects. Béla forced the new prince, Roman Mstislavich, to flee. After conquering Halych, he granted it to Andrew. Béla also captured Vladimir Yaroslavich and imprisoned him in Hungary.
