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.
Ferdinand II of Portugal
In keeping with Portuguese law, only after the birth of his son in 1837 did he acquire the title of king. Ferdinand's reign came to an end with the death of his wife in 1853, but he served as regent for his son and successor, King Pedro V, until 1855. He and Maria founded the House of Braganza-Saxe-Coburg and Gotha, which would rule Portugal until 1910.
