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.
List of monarchs of Brazil
Before 1815, Brazil was a colony of the Kingdom of Portugal. Thus, from the formal arrival of the Portuguese in 1500, when the land was claimed by the Portuguese Crown, until 1815 when the Kingdom of Brazil was created and the colonial bond was formally terminated and replaced by a political union with Portugal, the Kings of Portugal were monarchs "over" Brazil.
