History of Portugal (1834–1910)
Militant Republicans and their allies in the Carbonária were not willing to remain in the shadows of the constitutional monarchy. Between 4–5 October 1910, members of the Carbonária, republican youth, and elements of the army instigated a coup d'état against the already weak constitutional monarchy. The young king and his family, after a few miscues, escaped from the Palace in Mafra to exile in England. On the morning of 5 October 1910, the Republic was declared from the balcony of Lisbon City Hall, ending eight centuries of monarchy in Portugal.

Although Portuguese monarchs were not crowned since the 16th century, it was decided by the newly created imperial Government that the Brazilian monarchy, then recently instituted, should adopt different customs, both to differentiate itself from the Portuguese model and to highlight its status as a distinct institution, from a separate and independent country. Thus, it was decided that Emperors of Brazil should be consecrated, anointed and crowned with the full Catholic coronation ritual. Also, in the context of the struggle to sustain the newly declared independence of Brazil, and to seek recognition for the Empire, the religious act of coronation would establish Emperor Pedro I as an anointed monarch, crowned by the Catholic Church. It was regarded that this could improve his legitimacy in the eyes of other Christian monarchies, and it would also confirm the alliance between the newly declared State and the Church in Brazil. Accordingly, the coronation of Emperor Pedro I took place on 1 December 1822.
