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.
History of Portugal (1777–1834)
In 1807, Napoleon ordered the invasion of Portugal and subsequently the royal family and its entire court migrated to Brazil, Maria I declaring the United Kingdom of Portugal, Brazil and the Algarves in 1816. This would be one of the causes for the declaration of Brazilian independence by Pedro I of Brazil in 1822, following a liberal revolution in Portugal.
