He is remembered primarily as an administrator and builder whose legacy is bridges, towns, churches, hospitals and castles.
Pedro was the son of Diego Alfonso Tenorio, whose ancestors came from Pontevedra, and Juana Duque of Talavera de la Reina.
His first recorded ecclesiastical office was the archdeaconry of Toro, where he successfully sued his predecessor, Diego Arias Maldonado, for mismanaging the benefice.
[1] When King Peter the Cruel came to power, Pedro and his brothers fled to France with a large quantity of silver and gold.
The archdeaconry was taken from him and bestowed on a son of Mateos Ferrández de Cáceres, a close associate of the king.
[1] Juan died in papal Avignon, while Mendo was lured back with a false safeconduct and murdered on the king's orders.
[7] At the renewed outbreak of civil war in Castile, he left to join the army of Count Henry of Trastámara.
Two rival popes appeared, Urban VI at Rome and Clement VII at Avignon.
[1] His neutral approach was approved in a royal council and maintained for two years before, in 1381, Castile officially recognized Clement VII.
With Clement VII's support, he intended to convert the collegiate church of Talavera from secular canons to regular, but the plan failed.
[1] In 1390, he built a bridge over the Tagus and the attached town of Villafranca, today known as El Puente del Arzobispo.
[17] This bridge was open to the public and permitted pilgrim traffic to the monastery of Saint Mary of Guadalupe.
[18] In Toledo, he renovated the bridge of Saint Martin and built the gate known as the Puerta del Sol.
[23] This period was marked by the Seville pogrom (1391), a Nasrid raid on Murcia (1392) and a fifteen-year truce with Portugal (1393).
[24] Later that year, he obtained a papal judgement against the crown in order to regain possession of the castles of Alcalá, La Guardia, Talavera and Uceda.
