in the town of Moura with his maternal grandmother Beatrice, Duchess of Viseu, and was joined in the early months of the following year by his future wife, the ten-year-old Isabella. She spent three years in Portugal before returning home. Isabella also spent a considerable part of her youth on campaign with her parents as they conquered the remaining Muslim states in southern Spain. For example, she accompanied her mother in accepting the surrender of the city of Baza.
