This is a list of Portuguese monarchs who ruled from the establishment of the Kingdom of Portugal, in 1139, to the deposition of the Portuguese monarchy and creation of the Portuguese Republic with the 5 October 1910 revolution.
Through the nearly 800 years in which Portugal was a monarchy, the kings held various other titles and pretensions. Two kings of Portugal, Ferdinand I and Afonso V, claimed the crown of Castile and waged wars in order to enforce their respective claims. Ferdinand I managed to be recognized as King of Galiza in 1369, although his dominance of the region was short-lived. When the House of Habsburg came into power, the kings of Spain, Naples, and Sicily also became kings of Portugal. The House of Braganza brought numerous titles to the Portuguese Crown some honorary, such as the attribution of the title of Rex Fidelissimus (His Most Faithful Majesty), and royal titles, such as King of Brazil and then de jure Emperor of Brazil.
After the demise of the Portuguese monarchy, in 1910, Portugal almost restored its monarchy in a revolution known as the Monarchy of the North, though the attempted restoration only lasted a month before destruction. With Manuel II's death, the Miguelist branch of the house of Braganza became the pretenders to the throne of Portugal. They have all been acclaimed king of Portugal by their monarchist groups.
The monarchs of Portugal all came from a single ancestor, Afonso I of Portugal, but direct lines have sometimes ended. This has led to a variety of royal houses coming to rule Portugal, though all having Portuguese royal lineage. These houses are:
The Portuguese House of Burgundy, known as the Afonsine Dynasty, was the founding house of the Kingdom of Portugal. Prior to the independence of Portugal, the house ruled the feudal County of Portugal, of the Kingdom of Galicia. When Afonso Henriques declared the independence of Portugal, he turned the family from a comital house to a royal house which would rule Portugal for over two centuries. During the Reconquista, the Afonsine Dynasty expanded the country southwards until the definitive conquest of Algarve with Sancho II and the establishment of the Kingdom of Algarve, in 1249, under Afonso III. When Ferdinand I died, a succession crisis occurred between 1383 and 1385. Ferdinand's daughter Beatrice of Portugal was proclaimed queen and her husband John I of Castile proclaimed king by the right of his wife. Her legitimacy as a monarch is disputed.[1][2]
The House of Aviz, known as the Joanine Dynasty, succeeded the House of Burgundy as the reigning house of the Kingdom of Portugal. The house was founded by John I of Portugal, who was the Grand Master of the Order of Aviz. When King John II of Portugal died without an heir, the throne of Portugal passed to his cousin, Manuel, Duke of Beja. When King Sebastian of Portugal died, the throne passed to his Grand-uncle, Henry of Portugal (he might be called Henry II because Henry, Count of Portugal, father of Alphonso I of Portugal, was the first of that name to rule Portugal). When Henry died, a succession crisis occurred and António, Prior of Crato, was proclaimed António of Portugal.
