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.
List of Portuguese monarchs
After the demise of the Portuguese monarchy, in 1910, Portugal almost restored its monarchy in a revolution known as the Monarchy of the North, though the attempted restoration only lasted a month before destruction. With Manuel II's death, the Miguelist branch of the house of Braganza became the pretenders to the throne of Portugal. They have all been acclaimed king of Portugal by their monarchist groups.
