Agnes of Aquitaine, Queen of León and Castile

Agnes of Aquitaine was a member of the House of Poitou and an Iberian queen in the 11th-century. She was initially solely queen of León, then also of Castile by her marriage to Alfonso VI. Additionally, she appears to be the first Iberian queen-consort foreign to the peninsula, being of Frankish origin, the women preceding her were largely Christian Iberians or Muslim princesses of the Banu Qasi.
