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.
Duke of Loulé
When the deposed King Manuel II of Portugal died in 1932, Constança Maria was the representative of the House of Loulé (4th Duchess of Loulé, if one counts all the subsequent heirs of the original duke, including those that never registered the ducal title as required by law during the monarchy).
