ANSWER When the Emperor Charles V of Hapsburg became also King Charles I of Spain in 1516
In 1516, Charles V became the King of Spain. Spain ended up becoming more firmly enmeshed with the dynastic struggles of Europe.
Charles I was the King of Spain from 1516 until his death in 1556.
The King of Spain in 1525 was King Ferdinand who ruled from 1516 to 1555. His wife was his first cousin who he married in 1525 and her name was Isabella.
The King of Spain in 1552 was Charles I. Charles I ruled Spain from 1516 to 1556. He gave up some of the territory owned by Spain to his son Philip II in 1552. And then made his brother, Ferdinand, King of Spain the same year. This split the Netherlands away from Spain's rule.
King Ferdinand was the effective King of Spain in 1513. He was the de jure King of the Kingdom of Aragón and he was the de jure Regent for Queen Joanna of Castile who was deemed mentally ill. In 1516, the Kingdom of Spain passed to Charles V of the Hapsburgs.
There was not a king and queen of Spain in 1492. Ferdinand II ruled Aragon and co-ruled Leon and Castile with Queen Isabel I. Isabel I was Queen of Castile and Leon and co-ruled Aragon with Ferdinand. They ruled those three kingdoms together but were only the Monarchs of their own kingdom(s). Consequently they were not the monarchs of Spain. Nor were their children. Spain was only unified when all three kingdoms were inherited by their grandson Carlos I of Spain in 1516. At that point it became one kingdom. Carlos I was Crowned Holy Roman Emperor in 1519, and King of Bologna on 22 February, 1530. All told he was King of Spain first (1516), Holy Roman Emperor later(1520), and still later King of the Romans and King of Italy(1530). Charles abdicated his various title in 1555. There was not a king and queen of Spain in 1495.
Philip II of Spain was King of Spain from 1556 until 1598
Germany was NEVER part of Spain. However, from 1516/1519 to 1700 they were both ruled by the same dynasty, the Habsburgs (also spelled Hapsburgs). The Spanish king was never German king, with the exception of Charles V (lived 1500-1558, ruled 1516-1556), who was both.
Charles V, Emperor of the Holy Roman Empire, who was also elected First King of Spain in 1516 with the name of Charles I King of Spain.
The area that became Spain was completely freed of Moors in 1492. At that time it was known as the kingdoms of Castile, Leon, and Aragon, not Spain. Spain came into existence in 1516 when the three separate kingdoms were united as the inheritance of Felipe II who was the grandson of Queen Isobel I, Queen of Castile and Leon, and Ferdinand II, King of Aragon.
