In his last will in 1502, Andreas Palaiologos again ceded his self-awarded imperial title, this time to Ferdinand II of Aragon and Isabella I of Castile. Other pretenders to the Byzantine throne have appeared following his death that year, with increasingly dubious claims as centuries went by. Charles I Gonzaga, Duke of Mantua, who also claimed descent from the Palaiologos family, declared in 1612 his intent to reclaim Constantinople but only succeeded in provoking an upraising in the Mani Peninsula, which lasted until 1619.
