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.
Flag of Portugal
With the invasion of Portugal by Napoleon's imperial army in 1807, the Portuguese Royal Court fled to Brazil, establishing the capital of the Portuguese Monarchy and Empire in Rio de Janeiro. In 1815, the Portuguese state of Brazil was elevated to a kingdom, thus receiving the same status as the Kingdom of Portugal and the Algarves. The whole of the Portuguese Monarchy became then the United Kingdom of Portugal, Brazil and the Algarves. To reflect the change of the status of the Portuguese Monarchy, the Prince Regent John (future King John VI, at that time still reigning in name of his mother, Queen Mary I) established a new Royal coat of arms, where the Portuguese shield (representing Portugal and the Algarves) charged a blue-filled yellow armillary sphere (representing Brazil) surmounted by the same beret-bearing five-arched crown. The new coat of arms replaced the previous one in the Portuguese flags.
