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.
Flag of Portugal
Despite the end of the United Kingdom of Portugal, Brazil and the Algarves, when Brazil became independent in 1822, its coat of arms continued to be used, inclusive in flags, until the death of John VI in 1826. From then on, the previous coat of arms, without the armillary sphere, became in use again.
