Sancho Fernández, Arzobispo de Sevilla y de Toledo

"Castile, Sancho de. ?, 1233 – 27.X.1261. Infante of Castilla, administrator of the Archdiocese of Toledo (March 11, 1251-October 1259) and Archbishop of this see (October 1259-October 27, 1261).
Sixth of the sons of Fernando III, King of Castile, and his first wife, Beatriz de Suabia, eighth in the chronological order of birth. The decisive intervention of Fernando III in the appointment of bishops, not only of the recovered dioceses, but of all the headquarters of their kingdoms, had in his two sons, Felipe and Sancho, carefully prepared for it, instruments of great importance.
Both were entrusted to the care of Rodrigo Jiménez de Rada, Archbishop of Toledo (1209-1247), the most relevant figure on the political, ecclesiastical and cultural scene in Castile in recent decades; the two trained for a time in Paris and received prebends in the Toledo church, of which Sancho was a canon and archdeacon.
As the prince that he was, Sancho participated together with his father, probably, in the operations that led to the surrender of Seville and, of course, in the tasks of organization and division that followed the reconquest of the city; he also participated in the military actions against Medina Sidonia, Alcalá, Vejer and Lebrija, among others. He was in Seville at the time of his father's death in May 1252.
After the death of Rodrigo Jiménez de Rada, the brief pontificates of Juan de Medina de Pomar (1248), elevated by pontifical decision, after rejecting the election made by the capitulants, and of Gutierre Ruiz de Olea ( 1249-1250), who by royal will had first been promoted to the see of Córdoba and, later, transferred to that of Toledo. Upon his death, Fernando III promoted the election of his own son Sancho and required the confirmation of Innocent IV.
It was a very important step towards effective control over the episcopate of his kingdom, especially in places as important as Toledo. He had advanced in this project since, in 1237, Gregory IX recognized the right of presentation to him in the episcopal sees restored after the reconquest: by virtue of this recognition he had obtained, in February 1249, as soon as Seville was reconquered, the designation of his son Felipe as administrator of the metropolitan see restored there.
As in the case of Seville, given the lack of canonical age to hold the position, which was established at thirty years, Don Sancho was appointed administrator of the archdiocese of Toledo (March 11, 1251); this situation continues until 1259, when he reaches the expected canonical age. He, of course, acts as archbishop already in October of this last year.
His designation supposes for the Toledo headquarters the concession by the King of Hita, Uceda and Iznatorraf, the lands won by Rodrigo in the area of ​​Baeza and 5,000 maravedís; 2,000 more maravedís in the almojarifazgo in Toledo and another 2,000 in sales in Guadalajara and Escalona, ​​in addition to Baeza's promise, as Rodrigo had been promised. Undoubtedly the promise of these concessions had weighed decisively on the Pope's mind to confirm the proposed candidate.
During Don Sancho's stage as administrator of the diocese, a Provincial Council was held, which had Alcalá de Henares, Buitrago and Brihuega as successive headquarters, from the end of 1257 to April 1258; there is no news about their deliberations.
Don Sancho's premature death, in October 1261, prevents us from having other news of his pontificate." [https://dbe.rah.es/biografias/24902/sancho-de-castilla]
