Book excerpt: Originally published in 1949. Lacking the warlike bluntness of his predecessor, Richard the Lionheart, John came to the throne of England at a time when economic forces in the realm were threatening to undermine the very basis of feudal power. The Reign of King John covers his attempts to adjust a political system to cope with this threat and at the same time to assert the hegemony of the monarchy over its chief rivals—the barons and the church—made his reign one of particular importance and significance in English history.
