The childless Ladislaus IV of Hungary (1262-1290), was succeeded by Andrew III as King of Hungary. He was the son of Stephen the Posthumous, considered by Stephen's much older half-brothers (Béla IV of Hungary, Coloman of Halych, Andrew II of Halych) a bastard son of infidelity. For this reason, after the death of Ladislaus IV. some of the Árpád dynasty's cognates sought the family as extinct. In Naples, Charles Martel of Anjou, the eldest son of Mary of Hungary announced his claim to the Hungarian crown, backed by his mother, and the pope. He started to style himself king of Hungary, but he never managed to gain enough support from the Hungarian magnates to realize his claim.
