Manuel II of Portugal
"Dom" Manuel II (15 November 1889 – 2 July 1932), "the Patriot" () or "the Unfortunate" (), was the last King of Portugal, ascending the throne after the assassination of his father, King Carlos I, and his elder brother, Luís Filipe, the Prince Royal. Before ascending the throne he held the title of Duke of Beja. His reign ended with the dissolution of the monarchy in the 5 October 1910 revolution, and Manuel lived the rest of his life in exile in Twickenham, South London.
Duarte Nuno, Duke of Braganza
Duarte Nuno’s second brother, Prince Francis Joseph of Braganza, died in 1919, and on 21 July 1920 his eldest brother, Prince Miguel, Duke of Viseu, renounced his succession rights. Ten days later on 31 July 1920 Duarte Nuno’s father, Miguel, abdicated his claim to the Portuguese throne in favour of Duarte Nuno. Henceforth the Miguelists recognised Duarte Nuno as "King Duarte II of Portugal", even though Portugal had become a republic in 1910 when Maria II’s great-grandson, King Manuel II (who was still living in 1920), was sent into exile. Duarte Nuno used "Duke of Braganza" as a title of pretense.
