Input: The new peace would only last for two years; war recommenced in the aftermath of John's decision in August 1200 to marry Isabella of Angouleme. In order to remarry, John first needed to abandon Isabel, Countess of Gloucester, his first wife; John accomplished this by arguing that he had failed to get the necessary papal permission to marry Isabel in the first place as a cousin, John could not have legally wed her without this. It remains unclear why John chose to marry Isabella of Angouleme. Contemporary chroniclers argued that John had fallen deeply in love with Isabella, and John may have been motivated by desire for an apparently beautiful, if rather young, girl. On the other hand, the Angoumois lands that came with Isabella were strategically vital to John: by marrying Isabella, John was acquiring a key land route between Poitou and Gascony, which significantly strengthened his grip on Aquitaine.[nb 5]
Output:
How long did the new peace last?
