Abolition of monarchy
The monarchy of Portugal was also overthrown in 1910 (5 October), two years after the assassination of King Carlos I, ending the reign of Manuel II, who died in exile in England (1932), without issue.
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.
