Мартин I
On the death of King Frederick IV of Sicily, Manfredi III Chiaramonte became viceroy and tried to defend the throne of Sicily from Martin I of Sicily. Martin's father was the future King Martin I of Aragon, and his grandparents were King Peter IV of Aragon and Eleanor of Sicily. In 1389 he married Maria of Sicily, who was the only child and daughter of King Frederick IV. In 1392 he returned with Maria to Sicily with a military force and to defeat a group of opposing noblemen. However, the city of Palermo fell and the new King Martin I of Sicily had its governor, Andrea Chiaramonte, son of the late Manfredi, 8th Count of Modica, beheaded on 1 July 1392 in front of his palace in the Marina Square in Palermo.
