John deserted his dying father in 1189 and joined the rebellion of his brother Richard, who succeeded to the throne as Richard I in the same year. The new king generously conferred lands and titles on John. After Richard's departure on the Third Crusade, John led a rebellion against the chancellor, William of Longchamp, had himself acknowledged (1191) temporary ruler and heir to the throne, and conspired with Philip II of France to supplant Richard on the throne. This plot was successfully thwarted by those loyal to Richard, including the queen mother, Eleanor of Aquitaine. Richard pardoned John's treachery.
