Osorio Martínez

Besides the documentary sources, which are somewhat meagre at times after his fall from royal favour, he is mentioned in two episodes in the Chronica Adefonsi imperatoris.

In 1126 he joined the other noblemen of the Leonese province in swearing an oath of fealty to the new king Alfonso VII at the capital city of León.

[6] In July 1138 Rodrigo died at the Siege of Coria and the king immediately appointed Osorio count (comes) in his place and granted his tenencias of León,[7] Aguilar,[8] Campos,[9] and perhaps Zamora.

[4] Osorio and his brother's erstwhile vassals carried Rodrigo's body to the city of León for burial in the family mausoleum beside his parents.

There they buried him in a church next to the Cathedral of Santa María, possibly the monastery of San Pedro de los Huertos, which his parents had received by a royal grant of Urraca of Zamora and Elvira of Toro in 1099.

[1][13] (Calderón Medina and Ferreira suggest an additional child, Portuguese nobleman Monio Osores of Cabreira and Ribeira.

On 22 February 1140 he was at Carrión de los Condes to witness the treaty between Alfonso VII and Raymond Berengar IV of Barcelona.

[15] But in the summer of 1141 he fell from favour and his tenencias were confiscated (Melgar, Malgrat, Mayorga, Liébana, León, Aguilar, Campos, Zamora).

The villages in turn were required to make an annual payment in kind of half a sheep, ten loaves of bread, some barley, and some must.

[19] In 1159 Osorio and Teresa granted a third of the tithes of the churches of Villalonso, Benafarces, Carvajosa, Grallarejos and Pozoantiguo, which they claimed to own by hereditary right, to the Cathedral of Zamora.

[1] Osorio died at the hands of his son-in-law, Fernando Rodríguez de Castro, husband of his daughter Constanza, at the Battle of Lobregal in March 1160, fighting on the side of the House of Lara in the civil war for control of the regency of the young Alfonso VIII.
