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
Muslims called their conquests in Iberia 'al-Andalus' and in what was to become Portugal, they mainly consisted of the old Roman province of Lusitania (the central and southern regions of the country), while Gallaecia (the northern regions) remained unsubdued. Until the Berber revolt in the 730s, al-Andalus was treated as a dependency of Umayyad North Africa. Subsequently, links were strained until the caliphate was overthrown in the late 740s.
