Charles Martel, king of Hungary (born 1271)

Charles Martel of the Capetian dynasty was the eldest son of king Charles II of Naples and Mary of Hungary, the daughter of King Stephen V of Hungary. The 18-year-old Charles Martel was set up by Pope Nicholas IV and the ecclesiastical party as the titular King of Hungary (1290–1295) as the successor of his maternal uncle, the childless Ladislaus IV of Hungary against whom the Pope had already earlier declared a crusade.
