His relationship with the barons and the impact that this had on his relationship with other European countries and the papacy dominate his reign. Government was adapted as a result of these wars. Magna Carta was altered and reissued. The Provisions of Oxford led to a formal council that governed the country. Henry III is generally regarded as having been a weak military leader.
