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.
Portugal
About 410 and during the 6th century it became a formally declared Kingdom of the Suebi, where king Hermeric made a peace treaty with the Gallaecians before passing his domains to Rechila, his son. In 448 Réchila died, leaving the state in expansion to Rechiar.
After the defeat against the Visigoths, the Suebian kingdom was divided, with Frantan and Aguiulfo ruling simultaneously. Both reigned from 456 to 457, the year in which Maldras (457–459) reunified the kingdom to finish being assassinated after a failed Roman-Visigothic conspiracy. 
Although the conspiracy did not achieve its true purposes, the Suebian Kingdom was again divided between two kings: 
Frumar (Frumario 459–463) and Remismundo (son of Maldras) (459–469) who would re-reunify his father's kingdom in 463 and that he would be forced to adopt Arianism in 465 due to the Visigoth influence.
By the year 500, the Visigothic Kingdom had been installed in Iberia, based in Toledo and advancing westwards. They became a threat to the Suebian rule.
