Suero Vermúdez

Suero Vermúdez (or Bermúdez) (died 12 August 1138) was an Asturian nobleman, territorial governor, and military leader. His career was marked by loyalty to the crown of León-Castile during the reigns of Alfonso VI, Urraca, and Alfonso VII. He never took part in any revolt, but fought in many wars against rebels, against rivals, and against the Moors.

The primary sources for the life of Suero are the contemporary Historia compostellana and Chronica Adefonsi imperatoris plus some 150 surviving charters which mention, were drawn up by, or were confirmed by Suero. He held extensive lands and many interests in ecclesiastical properties. Out of his enormous wealth he was a generous patron of monasteries, and appears to have favoured the Benedictines and the Cluniac reform. The Chronica describes Suero, one of the few noblemen it praises, as "a man strong in counsel and a seeker of truth" and "a lover of peace and truth and a faithful friend of the king".
