Infante don Juan de Trastamara de Aragon y de Trastamara de Castilla, (
28 June 1478in Seville– 4 October 1497), Prince of Asturiasand heir of Spain, was the only son of Isabella I of Castileand Ferdinand II of Aragonwho survived to adulthood.
At the age of 18 Juan married Margaret of Austria (1480-1530) in the
Cathedral of Burgosin April, 1497. Six months later, on the way to the wedding of his older sister in Portugal, he died in Salamanca, possibly from tuberculosis. His wife was left pregnant and later gave birth to a stillborn child. Juan's death led to the inheritance of the Spanish kingdoms by the Habsburgs, after his sister married Philip the Handsome.
In 1492, Columbus named the newly discovered island of
Cuba"Isla Juana" in deference to Prince Juan, at that time the heir apparent.cite book| author= Andrea A.J., Overfield O.H.| title=The Human Record, Vol 1; Letter by Christopher Columbus concerning recently discovered islands | Publisher=Houghton Mifflin Company | year=2005 | page=P8|id=ISBN 0-618-37040-4]
