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.
Abolition of monarchy
In Spain monarchy was abolished from 1873 to 1874 by the First Spanish Republic, but then restored until 1931. The monarchy of Tahiti came to an end in 1880 when France made it a colony and overthrew King Pōmare V. That of Burma was abolished in 1885, when the last king, Thibaw Min, lost his throne and the country was annexed by Britain. In Brazil, the monarchy was abolished in 1889, when Emperor Pedro II was overthrown by a republican military coup (the status of the republic was fully confirmed by a plebiscite in 1993 that resulted in 66% of the votes to the republican government). In 1893 foreign business leaders overthrew Queen Liliʻuokalani of the Kingdom of Hawaii. They established a republic, which was annexed by the United States in 1898. The monarchy of Madagascar, known as the Merina Kingdom, came to an end in 1897 when France made it a colony and overthrew Queen Ranavalona III.
