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.

This was a disturbing prospect for John II, who trusted neither Manuel nor the powerful Order of Christ. During the purges of the high nobility in 1483–84, John II had ordered the execution of Manuel's own brother Diogo, Duke of Viseu and brother-in-law Fernando II, Duke of Braganza. Manuel himself only escaped a similar fate largely because John II regarded him as a harmless fool. Now that 'fool' stood to succeed him, and in John II's estimation, would likely undo all the king's hard-won centralizing reforms and deliver the kingdom back to the nobles.
