Carlos, rey emperador (transl.

'Charles, Emperor King') is a Spanish historical fiction television series based upon the reign of Charles V (Carlos I to the Spanish),[1] directed by Oriol Ferrer and produced by Diagonal TV for Televisión Española.

[2] The series is the sequel to the film The Broken Crown, which in turn is the sequel to the series Isabel produced by the same production company.

The series tells the story of Charles I or Charles V, Holy Roman Emperor, one of the most powerful men Europe has seen, the ruler of an empire as great in size as in diversity.

As the life of Charles of Habsburg is told since his arrival to Spain, it can be seen how the heir to the crowns of Germany, Burgundy, the Netherlands, the territories of the Crown of Aragon and its related Italian territories, and of the territories of the Catholic Monarchs in Castile, North Africa and the Americas, matures as a statesman and gets stronger in face of menaces around him and good and bad advice from his counselors.
