Through a formal document dated 4 April 1422, his maternal grandfather, the Constable Nuno Álvares Pereira, granted to him the County of Ourém. However, this grant only gained the Portuguese King Edward's royal confirmation on 24 November 1433.
Alphonse was sent by the King as his special ambassador to the Council of Basel (1436) and to the Council of Florence (1439), during which time he also visited Ferrara and Rome.
In 1458, Alphonse took part in the Portuguese expedition to north Africa which led to the capture of the Moroccan city of Alcácer Ceguer (Al Qsar as-Seghir).
