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.
Kingdom of Portugal
The Kingdom of Portugal (, ) was a monarchy on the Iberian Peninsula and the predecessor of modern Portugal. It was in existence from 1139 until 1910. After 1415, it was also known as the Kingdom of Portugal and the Algarves, and between 1815 and 1822, it was known as the United Kingdom of Portugal, Brazil and the Algarves. The name is also often applied to the Portuguese Empire, the realm's extensive overseas colonies.
