Charles V (Spanish: Carlos I, Dutch: Karel V, German: Karl V., Italian: Carlo V, French: Charles Quint, Turkish: Şarlken; 24 February 1500 – 21 September 1558) was ruler of the Holy Roman Empire from 1519 and, as Charles I, of the Spanish Empire from 1516 until his voluntary retirement and abdication in favor of his younger brother Ferdinand I and his son Philip II in 1556.

As the heir of three of Europe's leading dynasties—the House of Habsburg of the Habsburg Monarchy; the House of Valois-Burgundy of the Burgundian Netherlands; and the House of Trastámara of the Crowns of Castile and Aragon—he ruled over extensive domains in Central, Western, and Southern Europe; and the Spanish colonies in the Americas and Asia.

Charles was the eldest son of Philip the Handsome and Joanna the Mad. When Philip died in 1506, Charles became ruler of the Burgundian Netherlands, and his mother's co-ruler in Spain upon the death of his maternal grandfather, Ferdinand the Catholic, in 1516. As Charles was the first person to rule Castile-León and Aragon simultaneously in his own right, he became the first King of Spain (Charles co-reigned with his mother Joanna, which was however a technicality given her mental instability). In 1519, Charles succeeded his paternal grandfather Maximilian as Holy Roman Emperor and Archduke of Austria. From that point forward, Charles's realm, which has been described as "the empire on which the sun never sets", spanned nearly four million square kilometers across Europe, the Far East, and the Americas.

Bruno Eduardo Regufe Alves (born 27 November 1981 in Póvoa de Varzim) is a Portuguese footballer who plays for FC Zenit Saint Petersburg in Russia and the Portuguese national team, as a central defender.

Alves is noted for his strength, tough tackling and aerial ability. He spent most of his professional career at F.C. Porto, winning a total of nine titles, seven as first-choice.

After three consecutive loans, two in Portugal and another in the Greek first division with AEK Athens FC, Alves returned to F.C. Porto in 2005–06, extending his contract until 2010, and battling for a first-team spot with Ricardo Costa and João Paulo. He played in seven league matches for the eventual champions, but was infamously sent off on 15 October 2005, in the 2–0 home loss against S.L. Benfica, after headbutting Nuno Gomes.

The arrival of Jesualdo Ferreira at the helm of Porto signalled the turning point in Alves' career. He beat off stiff competition for a starting berth in the team alongside Pepe and formed a rock solid partnership with the Brazilian-born. An impressive season saw the player, now in his mid-twenties, finally come of age. Alves was ever-present as Porto won another national championship.
