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
In 1912, Duarte Nuno’s father, Miguel, met with Manuel to try to come to some agreement so that there would not be two claimants to the Portuguese throne, both living in exile. Their representatives allegedly signed the "Pact of Dover" by which Miguel recognised Manuel as king, while Manuel recognised the succession rights of Duarte Nuno should Manuel and his uncle Afonso die without children. The pact was unpopular with the supporters of both sides, some claiming that it was never actually signed.
