Lisbon Regicide
The assassination of King Carlos and the Prince Royal was the effective end of a constitutional monarchy in Portugal (later confirmed by the 5 October 1910 revolution). The regime functioned for another 33 months with growing agitation and demands for reform (although considerably less than in the future First Republic). It cannot be denied that the weak and permissive attitude in the Government of Acclamation was an incentive for the Republican Party to attempt another coup. The assassinations did not change the system of government; instead, they delayed the change.
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.
