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.
Pedro II of Brazil
The only legitimate male child of Pedro I to survive infancy, he was officially recognized as heir apparent to the Brazilian throne with the title Prince Imperial on 6 August 1826. Empress Maria Leopoldina died on 11 December 1826, a few days after a stillbirth, when Pedro was a year old. Two and a half years later, his father married Amélie of Leuchtenberg. Prince Pedro developed an affectionate relationship with her, whom he came to regard as his mother. Pedro I's desire to restore his daughter Maria II to her Portuguese throne, which had been usurped by his brother Miguel I, as well as his declining political position at home led to his abrupt abdication on 7 April 1831. He and Amélie immediately departed for Europe, leaving behind the Prince Imperial, who became Emperor Dom Pedro II.
