Lisbon Regicide
The assassination of King Carlos and the Prince Royal was the effective end of a constitutional monarchy in Portugal (later confirmed by the 5 October 1910 revolution). The regime functioned for another 33 months with growing agitation and demands for reform (although considerably less than in the future First Republic). It cannot be denied that the weak and permissive attitude in the Government of Acclamation was an incentive for the Republican Party to attempt another coup. The assassinations did not change the system of government; instead, they delayed the change.
United Kingdom of Portugal, Brazil and the Algarves
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.
