Italian explorer Amerigo Vespucci arrives back in Lisbon c. June 12, 1504 after his final verifiable voyage to the New World for the Portugese crown where he explored the East coast of South America. Upon his return, Vespucci declared that the lands explored were not Asia, but a distinct Mundus Novus (New World).
From Portugal, Amerigo Vespucci returned to Spain, where King Ferdinand appointed him Piloto Mayor (Pilot Major) of Spain. He continued to live in Spain and work for the Spanish government until his death in Seville on February 22, 1512. Vespucci's accounts from his travels inspired German cartographer (mapmaker) Martin Waldseemüller to label the continent "America" (feminine form of the Italian name Amerigo) in 1507. There are contested theories of two more voyages in 1505 and 1507. If so, they were conducted for the Spanish crown.
