Ermengol or Armengol VI (1096 – 1154), called el de Castilla, was the Count of Urgell from 1102 to his death. He was the son and successor of Ermengol V and María Ansúrez. He was born in Valladolid, whence his nickname comes. During his minority, he was under the regency of his grandfather, Pedro Ansúrez, lord of Valladolid, but the real power lay in the hands of Guerau II of Cabrera and Raymond Berengar III of Barcelona. With their help, the young count count conquered Balaguer in 1106 and made it his capital.
