Luís Filipe, Prince Royal of Portugal, (; Dom Luís Filipe Maria Carlos Amélio Francisco Víctor Manuel António Lourenço Miguel Rafael Gabriel Gonzaga Xavier Francisco de Assis Bento de Orleães Bragança e Saxe-Coburgo-Gotha ; 21 March 1887 – 1 February 1908 ) was the eldest son of King Carlos I of Portugal.

He was born in 1887 while his father was still Prince Royal of Portugal, and received the usual style of the heirs to the heir of the Portuguese crown: he was then at birth 4th Prince of Beira, with the subsidiary title of 14th Duke of Barcelos, private to the heir of the Dukedom of Braganza ; and after his grandfather king Dom Luís I died, he became Prince Royal of Portugal, with the subsidiary titles of 21st Duke of Braganza, 20th Marquis of Vila Viçosa, 28th count of Barcelos, 25th count of Ourém, 23rd count of Arraiolos, 22nd count of Neiva ; he was later created Knight Commander of the Order of the Immaculate Conception of Vila Viçosa, Knight of the Order of the Garter, and Knight of the Order of the Golden Fleece.

Dom Luís was born in Lisbon, the elder son of Carlos, Prince Royal of Portugal, ( later King Carlos I of Portugal ) and the Princess Amélie d ' Orléans.

Dom Luís Filipe was granted when born the titles of Prince of Beira and Duke of Barcelos, traditionally held by the heir apparent of the Prince Royal of Portugal ( Príncipe Real ).

Two years later, Dom Luís Filipe inherited all his father's royal princely titles when Charles became king, being himself restyled Prince Royal, and inheriting at the same time the Dukedom of Braganza ( 21st Duke ), the biggest private fortune in Portugal at that time, who was at the disposal of the heir to the Portuguese crown.

He in 1761 further granted Maria's eldest son, Infante Dom José Francisco ( 1761 – 88 ) the title Prince of Beira.

Queen Maria II and his regent, the future John VI, granted the Beira in turn to John's heirs-apparent, and the second of them, Infante Dom Pedro Francisco survived to become in 1816 the Prince of Brazil, the last Portuguese heir-apparent to held that ( as he himself later made Brazil independent ).

July 25, 1415 marked the beginning of the Portuguese Empire, when the Portuguese Armada departed to the rich trade Islamic centre of Ceuta in North Africa with King John I and his wife Phillipa of Lancaster and their sons Prince Duarte ( future king ), Prince Pedro, Prince Henry the Navigator ( born in Porto in 1394 ) and Prince Afonso, and legendary Portuguese hero Nuno Álvares Pereira.

Prince Pedro granted Henry the Navigator the monopoly of navigation, war and trade in the lands south of Cape Bojador.

After Henry of Trastamara successfully seized the throne of Castile, Pedro I fled to the court of the Black Prince in Aquitaine, who began to plot his restoration by sending an army across the Pyrenees.

In July 1366 Charles himself came to Bordeaux to consult with Pedro I and the Prince and agreed to keep the mountain passes of Navarre open for the passage of the army, for which he would be rewarded with the Castilian provinces of Guipúzcoa and Álava as well as additional fortresses and a large cash payment.

The Black Prince, affected by a dysentery, soon withdrew his support from Pedro.

In Shakespeare's Much Ado About Nothing, Benedick spots the sharp-tongued Beatrice approaching and exclaims to the Prince, Don Pedro, that he would do an assortment of arduous tasks for him " rather than hold three words conference with this harpy!

Edward, the Black Prince fought in the Battle of Nájera in 1367, intervening in a Castilian Civil War on behalf of Pedro of Castile.

During the same year in Lisbon, Maria II's throne was usurped by Prince Miguel, Pedro I's younger brother.

Prince Pedro, influenced by the Rio de Janeiro Municipal Senate ( Senado da Câmara ) refused to return to Portugal in the famous Dia do Fico ( January 9, 1822 ).

Her eldest son, Duarte, authored moral works and became king in 1433 ; Pedro, who travelled widely and had an interest in history, became regent when Duarte died of the plague in 1438 ; Fernando – Ferdinand the Saint Prince – who became a crusader, participated in the attack on Tangiers in 1437 ; and Henrique – Prince Henry the Navigator – became the master of the Order of Christ and the instigator and organiser of the early voyages of discovery.

The genealogical heir of Maria II's younger brother Emperor Pedro II of Brazil was his grandson Prince Pedro Gastão of Orléans-Braganza ; he too was not Portuguese, but the fact that he was Brazilian and therefore imbued with Portuguese culture made him a somewhat attractive candidate.

In 1945, Maria Francisca ’ s brother, Prince Pedro Gastão of Orléans-Braganza, relinquished to Maria Francisca and her heirs his rights to the title of Duke of Braganza, which had been created in 1816 in favor of his great-great-grandfather, Emperor Pedro I of Brazil.

The title was then inherited by Pedro II's daughter Isabel, Princess Imperial of Brazil, then by her eldest son Pedro de Alcântara, Prince of Grão Para, and then in turn by his son, Pedro Gastão.

Under traditional Portuguese nobiliary law, Prince Pedro Gastão could alter the succession to the title by relinquishing it to his sister.
