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.
Duarte Nuno, Duke of Braganza
After the death of his uncle Afonso in 1920, ex-King Manuel II had no close relatives who could claim the throne according to the Constitutional Charter of 1826 (the constitution in force from 1842 until the overthrow of the monarchy in 1910). The conflict between the Miguelist line and the Braganza-Saxe-Coburg and Gotha's was not just about which person should be sovereign; it was also about how much power the sovereign should have. The Miguelists upheld Portugal's tradition of autocratic absolutism, while the Braganza-Saxe-Coburg and Gotha's adhered to constitutional monarchy.
