Cardinal and Spanish politician, of noble family, he attended the court of Castile and in 1338 he was appointed archbishop of Toledo. He participated as tied to the preaching of the crusade against the Saracens of Andalusia; in Avignon in 1350 he was named cardinal by Clement VI. He linked his fame in particular to the pacification and political-administrative reorganization of the States of the Church in preparation for the return of the popes from Avignon to Rome, where, after the escape of Cola di Rienzo (1353), he had seized the city Francesco Baroncelli, who commanded you with dictatorial systems, while in the Papal States, tyrants were installed in power, which in practice had become independent of pontifical authority. Albornoz's task was particularly difficult, but he did not learn his strength: he first earned the neutrality of the governments of Milan and Tuscany to be safe behind and then brought Umbria and Lazio to obedience to the papal government. on the mutual jealousies of the lords who lorded you; then he called to Rome Cola di Rienzo, naming him senator for life, but the errors of the tribune were the cause of his death (1354) and Albornoz thus found the field clear of his work. He then headed the small army of the Holy See and defeated Malatesta in Rimini, Francesco Ordelaffi in Cesena and Giovanni Manfredi in Faenza. The following year (1358) he re-entered the rebellions of the Ordelaffi in Forlì and reduced to obedience Spoleto and Perugia. In 1363 Bologna was also subjected. The return to Rome of Urbano V in 1367 was due only to the skilled political-military work of Albornoz. The publication of the Liber Constitutionum Sanctae Matris Ecclesiae, also called in his honor Egyptian Constitutions, is the enduring result of this work. He is buried in Bologna, in the College of Spain he founded.
