One of the most notable of Portuguese knights of Santiago was Paio Peres Correia. Between 1234 and 1242, Correia led the conquest of much of the southerly Moorish dominions of Baixo Alentejo and the Algarve. In 1242, Paio Peres Correia was elevated to Grand Master of the Order of Santiago, the only known Portuguese to have held the supreme title of the Castilian-based Order.
