Dom Jaime I of Braganza (1479 – 20 September 1532) was the 4th Duke of Braganza and the 2nd Duke of Guimarães, among other titles. He is known for reviving the wealth and power of the House of Braganza, which was confiscated by King João II of Portugal.


Born in 1479, Jaime was young when he witnessed the arrest and execution of his father, Fernando II, Duke of Braganza, and of his uncle, Diogo I of Beja and Viseu. They were both executed for treason, when King João II of Portugal discovered a plot among the nobility against the Crown. After his father's death, Jaime's family, the House of Braganza, were banished to Castile and their properties and vast wealth were seized by the Portuguese Crown.

After King João II's death in 1495, the throne passed to João II's cousin, Manuel, Duke of Beja and Viseu. In 1498, Manuel I, having been a powerful nobleman before his ascension to the throne, forgave the House of Braganza and welcomed them back to Portugal. He returned all their possessions and then some, but demanded devout loyalty from the Duke of Braganza, Jaime I. With all his wealth returned, Jaime I saw to demonstrate the power of the House of Braganza by building the Ducal Palace of Vila Viçosa, a sumptuous Portuguese Renaissance palace in the Alentejo province of Portugal.

Royal Favour

Later in 1498, Manuel I was to go on a trip of duty to Castile, but at the time Manuel I had no heirs to throne, and Portugal had just seen a sort of succession crisis when Manuel I came to the throne. As Jaime I was the son of Isabel of Beja and Viseu, Manuel I's sister, Manuel I had the parlamentry cortes name Jaime I as heir presumptive to the throne of Portugal, a sign of true loyalty to the king, of which Jaime I accepted.

Jaime I married Leonor Pérez de Guzmán y Pérez de Guzmán, daughter of Juan Alfonso Pérez de Guzmán, 3rd Duke of Medina Sidonia. She was murdered in 1512, as per order by Jaime I for he suspected her of adultery. To escape imprisonment, Manuel I demanded Jaime I to prepare a fleet, funded solely by the Duke, to conquer the city of Azamor, on the Moroccan Atlantic coast. The city was easily conquered Duke's forces and he returned to Portugal forgiven and a hero.

Marriages and Children

In 1500, Jaime I married Leonor of Pérez de Guzmán, daughter of Juan Alfonso Pérez de Guzmán, 3rd Duke of Medina Sidonia. They had two children before she was killed in 1512.
