Kingdom of Portugal
After the Portuguese Restoration War of 1640–1668, the kingdom passed to the House of Braganza and thereafter to the House of Braganza-Saxe-Coburg and Gotha. From this time, the influence of Portugal declined, but it remained a major power due to its most valuable colony, Brazil. After the independence of Brazil, Portugal sought to establish itself in Africa, but was ultimately forced to yield to the British interests, leading to the collapse of the monarchy in the 5 October 1910 revolution and the establishment of the First Portuguese Republic.
Duke of Braganza
On 1 February 1908 King Charles I of Portugal was murdered along with his eldest son and heir, Luís Filipe, the last individual during the monarchy to carry that title. Carlos was succeeded by Manuel II of Portugal but for a short time: on 5 October 1910, a republic was instituted, and the king was exiled. King Manuel II then settled in England.
