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.
Regeneration (Portugal)
In the history of Portugal, the Regeneration (Portuguese - "Regeneração") is the name given to the period of the Portuguese Constitutional Monarchy after the military insurrection of 1 May 1851 that caused the end of Costa Cabral's tenure and of the Septembrist government. Despite the ministry that resulted from the strike, presided over by marshal Saldanha, the main person of the Regeneration was Fontes Pereira de Melo. Although it cannot be delimited definitely in the time, the period of the Regeneration endured for about 17 years, ending with the "Janeirinha" revolt in 1868, which brought the Reformist Party to power. The Regeneration was characterized by attempts to develop the country economically and modernize it, and the associated stringent fiscal measures.
