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.
Kingdom of Portugal
The Kingdom of Portugal (, ) was a monarchy on the Iberian Peninsula and the predecessor of modern Portugal. It was in existence from 1139 until 1910. After 1415, it was also known as the Kingdom of Portugal and the Algarves, and between 1815 and 1822, it was known as the United Kingdom of Portugal, Brazil and the Algarves. The name is also often applied to the Portuguese Empire, the realm's extensive overseas colonies.
