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.
United Kingdom of Portugal, Brazil and the Algarves
By a provision of the Letters Patent of 13 May 1825, confirmed by the Treaty on the Recognition of Independence in spite of the secession of Brazil from the Portuguese Monarchy, the Portuguese King, John VI, was allowed to use for the remainder of his life the honorary title of "Emperor of Brazil", with the caveat that this title was honorary and ceremonial only, and that Pedro I and his successors in the independent Brazilian Crown were the only actual Emperors of Brazil. This honorary title ceased to have effect upon the demise of King John VI on 10 March 1826.
