Charles V (24 February 1500 - 21 September 1558), reigned over the Holy Roman Empire since 1519. As Charles I, he was king of the Spain since 1516 until his abdication in 1556. Heir of four of Europe's leading dynasties - the Valois of Burgundy, the Habsburgs of Austria, the House of Aragon and the Trastamara of Castile - his domains in Central, Western, and Southern Europe, as well in the Spanish colonies in the Americas extended over about 4 million square kilometers.
Charles V represented the apex of Habsburg influence, with all the family's wealth united in one hand. After his death, the empire was split between his descendants, who received the Spanish possession and the Netherlands, and his younger brother, who received Austria, Bohemia and Hungary.
