A good politician and administrator, Henry I was the ablest of the Conqueror's sons. At his coronation on Aug. 5, 1100, he issued a charter intended to win the support of the nation. This propaganda document, in which Henry promised to give up many practices of the past, demonstrates how oppressive Norman government had become. Henry promised not to exploit church vacancies, as his brother had done, and guaranteed that reliefs, sums paid by feudal vassals when they took over their fathers' estates, would be "just and legitimate." He also promised to return to the laws of Edward the Confessor, though this cannot have been intended literally.
