On the recovery of Porto for Christianity, which was being promoted by the Burgundian Count Henry, son-in-law of King Alfonso VI of Castile and governor of the lands from the Minho River to the banks of the Tagus, priests and prelates were being imported, especially those with connections to Cluny in Burgundy. Hugo (Hugh) became bishop (1114-1136). He had been a Canon of the Cathedral of Compostella, and under the patronage of Bishop Diego Gelmirez, a Cluniac, he was said to have been a co-author of the "Historia Compostellana". In 1103-1104 he was sent to Rome on an embassy for the Church of Compostella, and obtained a bull granting numerous privileges, one of which was the right of the Bishop of Compostella to name Cardinals of Compostella. Hugo became a Cardinal. In 1109 he was Archdeacon of Compostella, but at the time of his election to the diocese of Porto and not yet ordained. He was ordained a priest on the day before Passion Sunday, and was consecrated a bishop on 23 March 1113 by Archbishop Mauricio Burdino of Braga, another Cluniac. As Bishop of Porto he secured from Pope Paschal II, by a bull granted on 15 August 1115, exemption of his diocese from the supervisory control of the Archbishop of Braga. He greatly enlarged his diocese and the cathedral patrimony increased by the donations he secured; thus, in 1120, he received from D. Theresa jurisdiction over the City of Porto with all the rents and dues thereof. Bishop Hugo was present at the Council of Compostella in 1114, the Council of Sagunto in 1121 (under the presidency of Cardinal Boso, the papal Legate), and the Synod of Compostella in 1122.
