Estado Novo (Portugal)
King Carlos I of Portugal confirmed colonial treaties of the 19th century that stabilized the situation in Portuguese Africa. These agreements were, however, unpopular in Portugal, where they were seen as being to the disadvantage of the country. In addition, Portugal was declared bankrupt twice—first on 14 June 1892 and again on 10 May 1902—causing industrial disturbances, socialist and republican antagonism, and press criticism of the monarchy. Carlos responded by appointing João Franco as Prime Minister and subsequently accepting Parliament's dissolution. In 1908, Carlos I was assassinated in Lisbon. The Portuguese monarchy lasted until 1910 when, through the 5 October revolution, it was overthrown and Portugal was proclaimed a republic. The overthrow of the Portuguese monarchy in 1910 led to a 16-year struggle to sustain parliamentary democracy under republicanism – the Portuguese First Republic (1910–1926).

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.
