By the late 1250s, resentment against the king's preferential treatment of his émigré Poitevin relatives led to a coup and the imposition of the Provisions of Oxford and Westminster, instituting a baronial council and more frequent parliaments. Pope Urban IV absolved the king of his oath in 1261 and, after initial abortive resistance, Simon de Montfort led a force, enlarged due to recent crop failures, that prosecuted the Second Barons' War. Bacon's own family were considered royal partisans: De Montfort's men seized their property and drove several members into exile.
