Henry II took decisive action to restore stability to England after the disorder and anarchy of Stephen's reign. He broke the power of overmighty barons by demolishing illegal castles and defeating barons in battle, forcing them to surrender castles. Henry also reasserted royal authority by reducing the power of earls, developing towns loyal to the crown, and appointing able men to offices rather than just those of noble birth. Through military success, financial reforms, and weakening the barons, Henry was able to strengthen royal authority and bring peace back to England.
