Teresa d'Entença

Teresa d'Entença (c. 1300–1327) was countess of Urgell in her own right. When her granduncle Ermengol X, count of Urgell, lay dying without children, he named the infante Alfonso of Aragon his heir, on condition that Alfonso marry Teresa as his rightful successor.

The wedding was celebrated at Lleida in 1314. She died at Zaragoza on 20 October 1327 giving birth to her son Sancho, only days before her husband ascended the throne as Alfonso IV. Her son Peter IV later ruled Aragon, while James inherited Urgell.
