Pedro González de Lara

Pedro González de Lara (died 16 October 1130) was a Castilian magnate and the first to call himself de Lara. First recorded as royal alférez in 1088 under Alfonso VI, he may have joined the First Crusade, earning the nickname el Romero.

Under Queen Urraca, whose lover he became, he was Castile's most powerful subject. He resisted Alfonso VII's accession and rebelled in 1130, seizing Palencia; captured and exiled, he was killed in a duel with Alfonso Jordan of Toulouse.
