Page "Charles V, Holy Roman Emperor" Paragraph 26

In the Castilian Cortes of Valladolid of 1506, and of Madrid of 1510 he was sworn as prince of Asturias, heir-apparent of his mother the queen Joanna.

On the other hand, in 1502, the Aragonese Cortes gathered in Saragossa, pledged an oath to his mother Joanna as heiress-presumptive, but the Archbishop of Saragossa expressed firmly that this oath could not establish jurisprudence, that is to say, without modifying the right of the succession, but by virtue of a formal agreement between the Cortes and the King.

So, with the death of his grandfather, King Ferdinand II of Aragon on 23 January 1516, his mother Joanna inherited the Crown of Aragon, which consisted of Aragon, Catalonia, Valencia, Naples, Sicily and Sardinia ; while Charles became Governor General.

Nevertheless, the Flemings wished that Charles assume the royal title, and this was supported by his grandfather the emperor Maximilian I and the Pope Leo X, this way, after the celebration of Ferdinand II's obsequies on 14 March 1516, he was proclaimed as king of Castile and of Aragon jointly with his mother.

Finally, when the Castilian regent Cardinal Jiménez de Cisneros accepted the fait accompli, he acceded to Charles's desire to be proclaimed king and he imposed his statement along the kingdom.

Thus, the cities were recognizing Charles as king jointly with his mother.
