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.
History of Portugal (1777–1834)
The history of the kingdom of Portugal and the Algarves, from the First Treaty of San Ildefonso and the beginning of the reign of Queen Maria I in 1777, to the end of the Liberal Wars in 1834, spans a complex historical period in which several important political and military events led to the end of the absolutist regime and to the installation of a constitutional monarchy in the country.
