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.
Afonso, Duke of Porto
The Prince had previously tried to get the king's approval for his marriage, but he found that his nephew and the rest of the royal family were vehemently opposed to it. After his marriage, his pension was cut by Manuel II, and Dom Afonso, also rejected by his relatives in the Italian royal family, began to live in obscurity and sickness during his final days. He finally died alone, in Naples, on 21 February 1920. Only one Portuguese servant remained with him until the end.
