The House of Aviz is a dynasty of kings of Portugal. In 1385, the Interregnum ended with the acclamation of the Master of the Order of Aviz, John, natural son of king Pedro I and Dona Teresa Lourenço as king. The descendants of king John I were still nominal masters of Aviz, though they were often replaced by other priests. The house of Aviz fell to the huge Spanish Empire, which transformed Portugal into a province, with the death of old king Henry I.
Cardinal Henry was succeeded by king Philip II of Spain. His domain would last until 1640, with the acclamation of the duke of Bragança as John IV of Portugal.
The dynasty began with the acclamation of Philip II of Spain as Philip I of Portugal in 1580, officially recognized in 1581 in the Cortes of Tomar.
The House of Braganza traced its origins to 1442 when the Duchy of Braganza was created by Alphonzo V and offered to his uncle Alphonzo, son of John I. The royal lineage of Dukes that followed intercrossed with the House of Aviz and became one of the most important noble families of the country.
The House of Braganza continues unofficially until today, and the title of Duke of Braganza is still used by Duarte Pio, the 24th Duke of Bragança and the presumptive heir to the throne of Portugal.
