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.
House of Braganza
In 1828, Maria II was forced into exile by her uncle, the new King Miguel I. Her father D. Pedro IV of Portugal returned from Brazil, launched a successful military campaign, from the Azores, against Miguel I. He finally defeated and exiled Miguel I in 1834. Though exiled, Miguel would not give up his claim to the throne and would establish the Miguelist branch of the House of Braganza. The strategic marriages of his children to the various royal houses of Europe would earn him the nickname the "Grandfather of Europe" ("see Descendants of Miguel I of Portugal").
