“The closer study of John’s history clears away the charges of sloth and incapacity with which men tried to explain the greatness of his fall. The awful lesson of his life rests on the fact that the king who lost Normandy, became the vassal of the Pope, and perished in a struggle of despair against English freedom was no weak and indolent voluptuary but the ablest and most ruthless of the Angevins.”

John Richard Green.
