In 1071, Bari was captured by Robert Guiscard, following a three-year siege. Maio of Bari (died 1160), a Lombard merchant's son, was the third of the great admirals of Norman Sicily. The Basilica di San Nicola was founded in 1087 to receive the relics of this saint, which were surreptitiously brought from Myra in Lycia, in Byzantine territory. The saint began his development from Saint Nicholas of Myra into Saint Nicholas of Bari and began to attract pilgrims, whose encouragement and care became central to the economy of Bari. In 1095 Peter the Hermit preached the first crusade there. In October 1098, Urban II, who had consecrated the Basilica in 1089, convened the Council of Bari, one of a series of synods convoked with the intention of reconciling the Greeks and Latins on the question of the filioque clause in the Creed, which Anselm ably defended, seated at the pope's side. The Greeks were not brought over to the Latin way of thinking, and the Great Schism was inevitable.
