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
Brazil was ruled by a series of monarchs in the period 1815–1889; first as a kingdom united with Portugal in the United Kingdom of Portugal, Brazil and the Algarves (1815–1822), subsequently as a sovereign and independent state, the Empire of Brazil (1822–1889). All four of the country's monarchs were members of the House of Braganza.
