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.

Following the Peninsular War, when the monarchy had remained transplanted in Brazil and continental Portugal was run by British-supported elites, pressure developed from professional classes to obtain more power, in light of their rule from abroad. Outward pressure eventually resulted in the 1820 Revolution, which established a Liberal constitution, investing power in the political structures and turning Portugal into a constitutional monarchy. King John VI of Portugal returned to the continent and supported this form of government, although during his reign there were pressures from the old elites such as the multiple attempts by his son Miguel of Portugal to overthrow the established Liberal constitution.
