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.
Monarchism in Brazil
The movement for the re-adoption of monarchy in Brazil has taken place as a series of uprisings and political acts, usually in a fragmented way and peripherally to larger causes. It has been important historically and remains an active movement to this day. It advocates restoration of the constitutional monarchy under the House of Orléans-Braganza, a cadet branch of the House of Braganza, which ruled Brazil for 77 years (the Empire of Brazil) until the monarchy was abolished in 1889 by a military coup d'état.
