King of Sicily from 1468 and King of Aragon from 1479 until his death. As a consequence of his marriage to Isabella I, he was King of Castile as Ferdinand V from 1474 until her death in 1504. He was recognised as regent of Castile for his daughter and heir, Joanna, from 1508 until his own death. In 1504, after a war with France, he became King of Naples as Ferdinand III, reuniting Naples with Sicily permanently and for the first time since 1458. In 1512, he became King of Navarre by conquest. Ferdinand is today best known for his role in inaugurating the discovery of the New World, since he and Isabella sponsored the first voyage of Christopher Columbus in 1492.
