# knowledge needed to understand Fermat's last theorem proof

It's a very soft question. So, Wiles proved Fermat's last theorem, and what knowledge of which area would be required to understand the theorem?

This feels like it might be a duplicate, but I can't find any. The creation of algebraic number theory was fueled in part by the quest to prove FLT, so there's an obvious area. –  anon Jul 13 '12 at 2:33

Do you want to understand the proof (as in the title of the question) or the theorem (as in the body)? Whichever, please edit so they match. –  Gerry Myerson Jul 13 '12 at 3:43
