If the sacred back was not always safe from family and associates in the Anglo-Saxon period, still less was it proffered in the Norman and Angevin periods. William I endured the rebellion of one son, William II an accidental death while hunting; Henry I suppressed a baronial rebellion in favor of his feckless brother Robert Curthose; Stephen's reign was characterized by lawlessness and rebellion on behalf of Empress Matilda.
