Carlos V (Gante, 1500 – Monasterio de Yuste, 1558) Holy Roman Emperor (Charles V) (1519–58) or Carlos I of Spain (1516–56) was the Emperor of the Holy Roman Empire from 1519 until his abdication in 1556. He was the son of Philip I of Castile and Juana of Castile and grandson of Ferdinand II of Aragon and Isabella I of Castile.
Charles sought to become a leader of a universal empire. The phrase "The Empire on which the sun never sets" is used to describe his empire at the time of his death. During his rule the Spanish Empire was enormously expanded in the New World.
