Abolition of monarchy
The monarchy of Portugal was also overthrown in 1910 (5 October), two years after the assassination of King Carlos I, ending the reign of Manuel II, who died in exile in England (1932), without issue.

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.
