Sancho succeeded his father in 1185. He had nine surviving children with his wife, Dulce of Aragon and he also had two children with a mistress. Upon his death in 1211, he was succeeded by his eldest son, now King Afonso II of Portugal.

He died in Sevilla in 1248 and was succeeded by his younger brother, now King Afonso III.
Afonso’s first marriage to Matilda II, Countess of Boulogne had taken place in 1239, but they had no children and divorced in 1253.

Henry had taken holy orders, which he attempted to renounce to further the Aviz dynasty. He died just two years without leaving legitimate issue, effectively ending the House of Aviz.
House of Habsburg
One of the closest dynastic claimants was King Philip II of Spain, as a grandson through the female line of King Manuel I of Portugal. He took Portugal by force and was soon elected King.

His first wife was Maria Manuela, Princess of Portugal, his second wife was Queen Mary I of England, his third wife was Elisabeth of Valois, and his fourth and final wife was his niece, Anna of Austria.

After Elisabeth’s death in 1644, he remarried to his niece, Maria Anna of Austria, in 1649. They had five children together, though only two children survived to adulthood. In 1640, Philip was expelled by the nobles of Lisbon, ending the union of Portugal and Spain.

John had married Carlota Joaquina of Spain in 1785, and they had nine children together. In 1825, the Empire of Brazil was proclaimed. Upon his death in 1826, he was succeeded by his eldest son, now King Peter IV and Emperor Peter I. Peter had married Maria Leopoldina of Austria in 1817, and they had seven children together before her death in 1826. He remarried to Amélie of Leuchtenberg in 1829, and he had one daughter by her. He was unable to deal with issues in Brazil and Portugal at the same time and abdicated the Brazilian throne in favour of his eldest surviving son, now Emperor Peter II of Brazil. Upon his death in 1834, he was succeeded by his eldest daughter, now Queen Maria II. This was disputed by Peter, and a compromise was reached where she would marry her uncle, Miguel. However, upon his arrival, he immediately deposed Maria and proclaimed himself King. She wasn’t restored as Queen until 1834.
On 26 January 1835, Maria married Auguste, Duke of Leuchtenberg but he died just two months later. On 1 January 1836, she married Prince Ferdinand of Saxe-Coburg and Gotha who received the title of King upon the birth of their first child in 1837. They went on to have 11 children, though Maria suffered greatly under the many pregnancies.

His wife and younger son survived, and he was succeeded by his youngest son, now King Manuel II. Manuel’s reign ended just two years later with the 5 October 1910 revolution. Thus, his mother Amélie was the last Queen of Portugal. Manuel married Augusta Victoria of Hohenzollern-Sigmaringen in 1913, but this happened after the abolishment of the monarchy. They had no children together, and upon Manuel’s death in 1932, his claim was inherited by Duarte Nuno, Duke of Braganza, a grandson of Miguel, who had deposed Queen Maria II. It is his son Duarte Pio who currently carries the claim to the Kingdom of Portugal.
