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.
Portugal in the Middle Ages
This process was essentially complete with the ascension of Afonso III of Portugal, the first to claim the title of "King of Portugal and the Algarve". The history of Portugal in the period between the death of Afonso III in 1279 and the beginning of the Portuguese Empire in 1415 includes the 1383–1385 Portuguese interregnum and the subsequent transition from the Portuguese House of Burgundy to the House of Aviz.
