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.
Manuel, Hereditary Prince of Portugal
After the death of Henry, King of Portugal, his family's return to Portugal and his father's acclamation as King on 24 July 1580, Manuel chose to go by the title of Prince of Portugal. However, his father's reign was short and troubled. He lost his title to King Philip II of Spain at the Battle of Alcântra. After hearing about this defeat, Manuel and his father fled to Coimbra to avoid imprisonment, and gathered six thousand men to face the Spanish troops once again. Nevertheless, they were once more defeated. With no options left, Manuel and his father were forced to hide in monasteries and friends' houses until they fled to France with the rest of the family. Before, António went to England, asking for Queen Elizabeth's support, which was granted, but the English troops never arrived to Portugal due to a bout of plague that killed most of the soldiers. Despite everything, António was still acclaimed as King in Azores until the Spanish troops arrived in 1583.
