Pedro González de Lara Pedro González de Lara (died 16 October 1130) was a Castilian magnate. He served Alfonso VI as a young man, and later became the lover of Alfonso's heiress, Queen Urraca. He may have joined the First Crusade in the following of Raymond IV of Toulouse, earning the nickname "el Romero" ("the wanderer, pilgrim"). At the height of his influence he was the most powerful person in the kingdom after the monarch. The proponderance of his power in Castile is attested in numerous documents between 1120 and 1127. He opposed the succession of Urraca's legitimate heir, Alfonso VII. This dispute ended with his premature death.
