House of Burgundy

The House of Burgundy ({{lang-pt|Casa de Borgonha}}) or Afonsine House (Dinastia Afonsina) was the first dynasty of Kings of Portugal. It began in 1139 and ended in 1383. Afonso Henriques (Afonso I) became king of Portugal after defeating his mother in the Battle of São Mamede in 1139. It was only in 1179 that Pope Alexander III recognized Portugal as an independent state, regognition, at the time, needed for a total acceptation of the kingdom in the Christian world. The kings that succeeded Afonso I continued the process of Reconquista of the Iberian Peninsula, controlled by Moors. Afonso III conquers Algarve and adopst the name of King of Portugal and the Algarves. The borders of Portugal were defined in the Treaty of Alcanizes (1297) when King Denis, son of Afonso III, started a process of development of the kingdom's land. In 1383 Beatrice, princess of Portugal and heir to the throne married John I of Castile. When Ferdinand I (her father) died during the same year the kingdom enters a period of anarchy called the 1383-1385 Crisis threatened be a possible anexation by Castile. This period ended in 1385 with the victory of the Portuguese in the Battle of Aljubarrota and a new dynasty began with John I, Master of Aviz (illegitimate son of Peter I), thus called the House of Aviz.
