In the final years of his reign, Henry was increasingly infirm and focused on securing peace within the kingdom and his own religious devotions. Edward became the Steward of England and began to play a more prominent role in government. Henry's finances were in a precarious state as a result of the war, and when Edward decided to join the crusades in 1268 it became clear that fresh taxes were necessary. Henry was concerned that Edward's absence might encourage further revolts, but was swayed by his son to negotiate with multiple parliaments over the next two years to raise the money.
