Miguel da Paz was born in
Zaragoza,
Spain on 23 August 1498. His mother, Isabella of Aragon, died within an hour of his birth. He was shortly sworn heir to the various Iberian crowns by the courts of Portugal, Castile and Aragon. For the next two years, he was the recognized heir of his father's kingdom of
Portugal and of the kingdoms of
Castile,
León and
Aragon, which he would inherit from his grandparents,
Ferdinand II of Aragon and
Isabella I of Castile. As such, he was styled
Prince of Portugal,
Prince of Asturias and
Prince of Girona. Miguel died in
Granada on 19 July 1500, in his grandmother's arms. He was buried in the
Capilla Real, in Granada. In October 1500, Miguel's father married
Maria of Aragon, who was also the younger sister of Miguel's mother. Maria gave birth to Manuel's eventual successor,
John III and to
several other children. The hopes of Isabella I and Ferdinand II to unite all of the
Iberian kingdoms vanished with Miguel's death. His aunt
Joanna inherited Castile, León and Aragon, and it was her grandson
Philip II who established a short-lived
Iberian Union. ==Ancestry==
