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
The invading Medieval Muslim Moors, who conquered and destroyed the Christian Visigothic kingdom in the Iberian Peninsula, were mainly Berbers from North Africa, but they were joined by Arabs from the Middle East.
By 714 Évora, Santarém and Coimbra had been conquered, and two years later Lisbon was in Muslim control. By 718 most of today's Portuguese territory was under Umayyad rule. The Umayyads eventually stopped in Poitiers but Muslim rule in Iberia would last until 1492 with the fall of the Kingdom of Granada.
