Manuel I of Portugal
Manuel's mother was the granddaughter of King John I of Portugal, whereas his father was the second surviving son of King Edward of Portugal and the younger brother of King Afonso V of Portugal. In 1495, Manuel succeeded his first cousin, King John II of Portugal, who was also his brother-in-law, as husband to Manuel's sister, Eleanor of Viseu.
Duke of Braganza
In the last years of the deposed king Manuel II of Portugal, the dukedom of Bragança was claimed by Miguel, Duke of Braganza, son of the exiled king Miguel I of Portugal, who was living in the Austrian Empire. His branch of the Braganza family allegedly became heirs to the crown in 1932, when Manuel II died without children. These Braganzas were officially allowed to return to the country in 1950 and have lived there ever since.
