As he returned from the Crusade, Richard was captured by Leopold V, Duke of Austria, and handed over to Henry VI, the Holy Roman Emperor, who held him for ransom. Meanwhile, John had joined forces with Philip Augustus, King of France. They sent a letter to Henry asking him to keep Richard away from England for as long as possible, offering payment to keep Richard imprisoned. Henry declined their offer, and got his ransom from Eleanor of Aquitaine (who had to pawn the Crown Jewels). Richard was set free. John then begged forgiveness from Richard, who granted it and named him heir presumptive.
