What is the main conflict in Life in a Medieval City by Frances Gies?

Life in a Medieval City provides a hypothetical, though factually researched and historically accurate, day in the life of the city of Troyes, the capital of the Champagne region of what is now modern-day France, in the year 1250. Rather than relying on the normal historical record of royals and wars, the book instead looks at life from an "everyday" perspective.
