The Most Serene House of Braganza (), also known as the Brigantine dynasty (dinastia Brigantina), is a dynasty of emperors, kings, princes, and dukes of Portuguese origin which reigned in Europe and the Americas.
The house was founded by Afonso I, 1st Duke of Braganza, illegitimate son of King John I of Portugal of the House of Aviz, and would eventually grow into one of the wealthiest and most powerful noble houses of Iberia during the Renaissance period. The Braganzas came to rule the Kingdom of Portugal and the Algarves after successfully deposing the Philippine Dynasty in the Restoration War, resulting in the Duke of Braganza becoming King John IV of Portugal, in 1640. The Braganzas ruled Portugal and the Portuguese Empire from 1640 and with the creation of the United Kingdom of Portugal, Brazil and the Algarves, in 1815, and the subsequent independence of the Empire of Brazil, in 1822, the Braganzas came to rule as the monarchs of Brazil.
The House of Braganza produced 15 Portuguese monarchs and all four Brazilian monarchs, numerous consorts to various European kingdoms, such as Catherine of Braganza (wife of Charles II of England who introduced tea to Britain) and Maria Isabel of Braganza (wife of Ferdinand VII of Spain who founded the El Prado Museum), as well as sometime candidates for the thrones of Poland and Greece, Infante Manuel, Count of Ourém and Pedro, Duke of Braganza, respectively, and numerous other notable figures in the histories of Europe and the Americas. The Braganzas were deposed from their thrones in Europe and the Americas at the turn of the 19th–20th centuries, when Emperor Pedro II was deposed in Brazil, in 1889, and when King Manuel II was deposed in Portugal, in 1910.
Feudal establishment
The House of Braganza originated with Afonso I, an illegitimate son of King John I of Portugal, founder of the House of Aviz, and Inês Pires. Though Afonso was illegitimate, his father valued and cared for him a great deal, demonstrated by his arrangement of Afonso's marriage to Beatriz Pereira de Alvim, daughter of Nuno Álvares Pereira, Portugal's most important general and a personal friend of King John I. As well as increasing his social status by his marriage into a well-established house, Afonso was also ceded the title of Count of Barcelos.
With his newly consolidated place in the nobility of Portugal, Afonso commenced what would be a highly successful political and social career. In 1415 he took part in the Conquest of Ceuta, alongside his father, his brothers, and the leading members of the nobility and military. By the time of his father's death in 1433, Afonso had won favour with his brother, King Duarte I and the rest of high Portuguese society. With his brother's premature death in 1438, a regency was established for Afonso's nephew, the 6 year old King Afonso V, under the leadership of the king's mother, Leonor of Aragon, and later Afonso's brother, Infante Pedro, Duke of Coimbra. The Duke of Coimbra's regency, however, soon proved unpopular and Afonso quickly became the King's preferred advisor. On 30 December 1442, the Duke of Coimbra, still the King's regent and thus acting in his name, created Afonso as the Duke of Braganza, as a gesture of good will and reconciliation between the two brothers. Afonso's elevation to the dukedom, the highest level of nobility, marked the foundation of the House of Braganza, which was to become a key family in Portuguese history.
As a result of the hard work and success of Afonso I, his children all secured successful positions and lived privileged lives. Afonso I's first son, Afonso of Braganza, was a prominent member of the nobility, having been granted, by his grandfather, Nuno Álvares Pereira, the lucrative and powerful title of Count of Ourém, in 1422. He was an accomplished diplomat, and served as the king's representative at the Council of Basel in 1436, and the Council of Florence in 1439. In 1451, the Count of Ourém was made Marquis of Valença and escorted Infanta Leonor of Portugal to her husband Frederick III, Holy Roman Emperor. Later, in 1458, he participated in the capture and conquest of Alcácer-Ceguer. The Marquis of Valença, however, died in 1460, one year before his father and therefore did not succeed him. Afonso I's first daughter, Isabel of Braganza, married Infante João, Lord of Reguengos de Monsaraz, thus relinking the House of Braganza to the Royal House of Portugal. Isabel's strategic marriage proved successful, and produced four children, whose descendants would be some of the most important in Iberian history. Afonso I's last child and successor, Fernando I, Duke of Braganza, continued his legacy of prominence in the military and society.
When Fernando I was born, in 1403, his grandfather, Nuno Álvares Pereira, ceded him the title of Count of Arraiolos. Fernando became an accomplished military man, participating in various Portuguese imperial campaigns. Though Fernando I was a popular and powerful member of the nobility, he did not always find himself in the favour of the king, most notably exemplified when Fernando I openly declaimed King Duarte I, at the Portuguese Cortes, on the topic of the rescue and recovery of the King's brother, Infante Fernando, Lord of Salvaterra de Magos from the Moors. However, Fernando I became a favourite of both the royal and imperial government and of King Afonso V, earning him the position of Governor of Ceuta and the titles of Marquis of Vila Viçosa and Count of Neiva.
Fernando I's children, by his wife, Joana de Castro, Lady of Cadaval, continued to enlarge the influence of the House of Braganza. Of his nine children, all six who survived to adulthood established themselves either through positions or marriages, though the actions of King João II would seek to weaken their influence. Fernando I's first son and successor, Fernando II, was initially a bright and popular nobleman, but his conflict with King João II would see his and the House's downfall. His second son, João of Braganza, 1st Marquis of Montemor-o-Novo, was an accomplished military man and was made Constable of Portugal. Fernando's third son, Afonso of Braganza, became a popular nobleman of society and was made 1st Count of Faro. The Duke's fourth son, Álvaro of Braganza, inherited the fiefs of his mother, becoming the 5th Lord of Ferreira, 4th Lord of Cadaval, and 1st Lord of Tentúgal. Fernando's eldest surviving daughter, Beatriz of Braganza, married Pedro de Meneses, 1st Marquis of Vila Real. Fernando's last surviving child, Guiomar of Braganza, married Henrique de Meneses, 4th Count of Viana do Alentejo. Ultimately, however, Fernando I's children and grandchildren would suffer great difficulty under the reign of King João II.
By the tenure of the third duke, Fernando II, the House of Braganza was undoubtedly one of the greatest noble houses of Portugal and Iberia as a whole. Fernando II continued the House's legacy of acquisition and gained the title of Duke of Guimarães. To the Duke and the House's downfall, however, King João II's reign concerned itself with the royal consolidation of power and the diminishment of the nobility. Fernando II, having been a prominent and powerful nobleman, was accused of treason and executed by King João II in 1483; the House's titles and properties were merged into the crown and its members exiled to Castile.
Due to their father's misfortunes, Fernando II's children, from his marriage to Isabel of Viseu, daughter of Infante Fernando, Duke of Viseu and Beja, initially had a tumultuous childhood; but King João II's successor, King Manuel I, who had previously himself been the Duke of Beja, chose to forgive the House and re-grant them all their properties in exchange for their loyalty. Fernando II's oldest surviving son and successor, Jaime I, returned to Portugal and reestablished himself at Vila Viçosa, the former seat of the Dukes. Fernando II's only other surviving son, Dinis of Braganza, married Beatriz de Castro Osório, Countess of Lemos, and had four children with her.
Portuguese Renaissance
Jaime I's tenure as Duke of Braganza was one of restoration and grandness. Upon his return to Portugal from exile, Jaime took possession of the House's formerly confiscated properties. In order to establish a new image for the House, he ordered the construction of a new seat for the House, which would become one of the largest palaces in Iberia, the Ducal Palace of Vila Viçosa. Jaime I's restoration also continued with the House's relations with the King, Jaime I having becoming a favourite of King Manuel I and even once his temporary heir. The Duke also had his share of scandal, having funded the conquest of the city of Azamor, for the royal crown as, as punishment for his ordering the murder of his first wife, Leonor Pérez de Guzman, daughter of Juan Alfonso Pérez de Guzmán, 3rd Duke of Medina Sidonia.
The children of Jaime I, both the two first children by his first wife, Leonor of Pérez de Guzman, and the later eight children by his second wife, Joana of Mendoça, all saw successful lives under the restored House of Braganza. Jaime I's first daughter, Isabel of Braganza, married Infante Duarte, Duke of Guimarães, and had three children, while his first son and successor, Teodósio I, was a successful prince of the Portuguese Renaissance. Five of Jaime I's children, Jaime, Maria, Fulgêncio, Teotónio, and Vicência, all entered into religious orders. The Duke's second daughter, Joana of Braganza, married Bernardino de Cardenas, 3rd Marquis of Elche, and his third daughter, Eugénia of Braganza, married Francisco de Melo, 2nd Marquis of Ferreira. Jaime I's only other son, other than Teodósio I, to not enter into the church, Constantino of Braganza, married Maria de Melo, daughter of D. Rodrigo de Melo, 1st Marquis of Ferreira, but had no children. Constantino was famed as a great officer of the Portuguese Empire, having served as the Viceroy of Portuguese India and Captain of Ribeira Grande, among other positions.
The fifth Duke, Teodósio I, is remembered for being the personification of the Portuguese Renaissance. A patron of the arts and scholarly noble, Teodósio I maintained the prestige of the House of Braganza, although not leaving a significant mark on the House's history. The Duke notably ceded the Dukedom of Guimarães to Infante Duarte of Portugal as the dowry of his sister, Isabel of Braganza.
Teodósio I's second son, Jaime of Braganza, died fighting alongside King Sebastião I at the Battle of Alcácer Quibir. The Duke's only daughter, Isabel of Braganza, married Miguel Luis de Meneses, 1st Duke of Caminha, though their union had no issue. Teodósio I's first child and successor, João I, lived a very different life from Teodósio I's calm and relatively peaceful tenure, having been involved in the controversies of the Portuguese succession crisis of 1580 and the subsequent War of the Portuguese Succession.
João I's tenure as Duke was one intertwined with controversy and intrigue. Having been married to Infanta Catarina, daughter of Infante Duarte, Duke of Guimarães, and thus a grandchild of King Manuel I, during the succession crisis of 1580, the couple pressed their claims to the Portuguese throne. Though Infanta Catarina was a popular claimant, her Habsburg cousin was eventually crowned Philip I of Portugal and the Iberian Union was established. In an attempt at reconciliation with the Brigantine House, King Philip I renewed the title of Constable of Portugal, which João I had held previously, to the Duke's first son, Teodósio II, alongside other title and land grants to the Duke and the House.
