Beltrán Vélez de Guevara, Marquis of Campo Real

[2] He began his career at court as a gentleman of the Chamber of Philip IV and of his younger brother, Cardinal-Infante Ferdinand of Austria, whom he accompanied to Flanders (1632), also serving, always as a gentleman of the Chamber, the other brother of the King, the Infante Don Carlos.

For all this, he obtained important favours from the monarch, the commission of various international missions and his trust within the court.

Together with his brother Íñigo Vélez, in 1626 he accompanied his father, the 5th Count, to Rome, where he established outstanding relations and completed his political-diplomatic training.

[3] However, his most notable intervention in the service of the monarchy came in 1650, when it was decided in Madrid that he should replace his brother Íñigo as Viceroy of Naples, while the former was away on a military campaign in Tuscany, which was threatened by the French.

[3] He was a member of the State Council of Philip IV of Spain and Viceroy of Sardinia between 1651 and 1652.
