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.
List of Portuguese monarchs
The monarchs of Portugal all came from a single ancestor, Afonso I of Portugal, but direct lines have sometimes ended. This has led to a variety of royal houses coming to rule Portugal, though all having Portuguese royal lineage. These houses are:The Portuguese House of Burgundy, known as the Afonsine Dynasty, was the founding house of the Kingdom of Portugal. Prior to the independence of Portugal, the house ruled the feudal County of Portugal, of the Kingdom of Galicia. When Alphonso I Henriques declared the independence of Portugal, he turned the family from a comital house to a royal house which would rule Portugal for over two centuries.
When Ferdinand I died, a succession crisis occurred and Ferdinand's daughter Beatrice of Portugal was proclaimed queen and her husband John I of Castile proclaimed king by the right of his wife. Her legitimacy as a monarch is disputed.
