The Reconquista (Reconquest) or Iberian Crusades were military campaigns largely conducted between the 11th and 13th century CE to liberate southern Portuguese and Spanish territories, then known as al-Andalus, from the Muslim Moors who had conquered and held them since the 8th century CE. With the backing of popes and attracting Christian knights from across Europe, including the main military orders, the successful campaigns ended by the final stages of the 13th century CE when only heavily fortified Granada remained in Muslim hands.
