The pressure for reform continued to grow unabated and a fresh parliament met in June, passing a set of measures known as the Provisions of Oxford, which Henry swore to uphold. These provisions created a smaller council of 15 members, elected solely by the barons, which then had the power to appoint England's justiciar, chancellor, and treasurer, and which would be monitored through triannual parliaments. Pressure from the lesser barons and the gentry present at Oxford also helped to push through wider reform, intended to limit the abuse of power by both Henry's officials and the major barons. The elected council included representatives of the Savoyard faction but no Poitevins, and the new government immediately took steps to exile the leading Lusignans and to seize key castles across the country.
