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
In 1910, there was a revolution that deposed the monarchy. Amid corruption, repression of the church, and the near bankruptcy of the state, a military coup in 1926 installed a dictatorship that remained until another coup in 1974. The new government instituted sweeping democratic reforms and granted independence to all of Portugal's African colonies in 1975.
