Arias Pérez

At some point Pedro granted an estate, a portion of a certain Villa nova, probably Vilanova de Arousa in Deza, to the church of nearby Compostela.

[4] Arias got Diego Gelmírez, the most powerful churchman in Galicia, to accept the leadership of the brotherhood late in 1109 or early in 1110.

In 1110 a truce between Pedro and the brotherhood was broken when the former took over the south Galician fortress of Castrelo de Miño and installed a garrison there under his wife Urraca and the young Alfonso.

[4][5] After the coronation of Alfonso and reconciliation of the Galicians with the queen in 1111, Arias was besieged in Lobeira with the aid of royal forces, and there he was captured in April 1112.

She tried to confiscate the property of the three Bodán brothers from Deza, including the monastery of Bodaño or Budiño in Arias's area of interest.

[6] In 1120, according to the Historia, Urraca ordered the leading men (principes) of Galicia, including Arias Pérez, Fernando Yáñez, Bermudo Suárez, Juan Díaz, and others, to do homage (hominium) to Diego Gelmírez as "their lord, their patron, their king and their prince, saving their fealty to the queen" and recognise his rule (dominio).

[14] Diego's opinion of Arias was such that he said to him: "I fear, therefore, that if such that you are you leave this world, you will lose eternal life and incur the perpetual condemnation of your soul.
