Beatrice of Portugal, Countess of Alburquerque

Beatrice of Portugal (c. 1354 – July 5, 1381) was Countess of Alburquerque as the wife of Sancho Alfonso of Alburquerque. She was the daughter of Peter I of Portugal and his wife Inês de Castro.

Life
Beatrice's entitlement to be considered an Infanta of Portugal is debatable. Some historians consider her a natural daughter of Peter I, so that title could never be attributed to her. Other opinions assert that after inheriting the throne, the Prince admitted that he had married Inês secretly, and she was thus a lawful Queen of Portugal.

Beatrice became Countess of Alburquerque when she married Sancho Alfonso of Alburquerque in 1373. Beatrice held this title for a year, until her husband died on 19 February 1374.

Children
Beatrice and Sancho Alfonso of Alburquerque had one daughter:


 * Eleanor of Alburquerque. (c. 1374–December 16, 1435). Married Ferdinand I of Aragon.
