ThePortuguese House of Burgundy (Portuguese:Casa de Borgonha) was a Portuguese noble house that ruled theCounty and laterKingdom of Portugal from its founding until the1383–85 Portuguese Interregnum.
The house was founded byHenry of Burgundy, who becameCount of Portugal in 1096. His son,Afonso Henriques, was proclaimedKing of Portugal following his victory at theBattle of Ourique in 1139, establishing theAfonsine dynasty (Dinastia Afonsina). Burgundian monarchs would rule Portugal through much of its early formation, including the formalization of thePortuguese language underKing Dinis I, the firstPortuguese parliament, underKing Afonso II, and the conquest of theKingdom of the Algarve, underKing Afonso III. Numerous princes of the house took up thrones across Europe, such asFerdinand I, Count of Flanders andPeter I, Count of Urgell. Similarly, many princesses became royal consorts, includingBerengaria, Queen of Denmark,Leonor, Queen of Aragon, andTeresa, Duchess of Burgundy, among others.

Henry, Count of Portugal, a grandson in the senior line ofRobert I, Duke of Burgundy, had joined theReconquista in theIberian Peninsula in the late 11th century. After conquering parts of Galicia and northern Portugal on behalf ofAlfonso VI of León, he married Alfonso's illegitimate daughter,Teresa, and was given the County of Portugal as a fief under theKingdom of León.
His son,Afonso Henriques, became King of Portugal after defeating his mother in theBattle of São Mamede in 1128. It was only in 1179 thatPope Alexander III recognized Portugal as an independent state,[1] recognition, at the time, needed for total acceptance of the kingdom in theChristian world.
On his mother's side, Afonso I of Portugal is connected to theJiménez dynasty, and throughSancha of León, to theAstur-Leonese dynasty, making him a descendant ofPelagius of Asturias. As theChronicle of Alfonso III identifies Pelagius as a grandson ofChindasuinth, this would make Afonso I the descendant ofLiuvigild. Liuvigild was King of theVisigoths in the 6th century (seeVisigothic dynasty), who conquered theSuebi Kingdom, thus controlling most of the Iberian Peninsula (and all of what would be Portugal, seeVisigothic Kingdom). On his father's side, Afonso I of Portugal is connected to theCapetian dynasty, a branch of theFrankishRobertians that goes back toRobert II, Count of Hesbaye in the 9th century.

The kings that succeeded Afonso I continued theReconquista of theIberian Peninsula against theMoors.Afonso III conquered theAlgarve and adopted the title ofKing of Portugal and the Algarve.
The borders of Portugal were defined in theTreaty of Alcanizes (1297) when kingDinis I, son of Afonso III, started developing the kingdom's land.
In 1383Beatrice, princess of Portugal and heir to the throne marriedJohn I of Castile. WhenFerdinand I (her father) died during the same year the kingdom entered a period of anarchy called the1383-1385 Crisis, threatened with a possible annexation byCastile.
This period ended in 1385 with the victory of the Portuguese in theBattle of Aljubarrota and a new dynasty began withJohn I, Master of Aviz (illegitimate son of Peter I), thus called theHouse of Aviz.
