 In 1163, under the terms of an existing peace treaty, King Stephen III's younger brother Béla was sent to Constantinople to be raised under the personal tutelage of the emperor himself.As Manuel’s relative (Manuel's mother was a Hungarian princess) and the fiancé of his daughter, Béla became a "Despotes" (a title newly created for him) and in 1165 he was named as an heir to the throne, taking the name Alexios.Since he was also the heir to the Hungarian throne, a union between the two states was a distinct possibility.
