Tl;dr.

I think that the Faunus War was the most recent, given Blake's backstory. The White Fang formed shortly afterwards, but it was only recently that it became a terrorist organization. That means that even though Blake may not have been around for its founding, it is certainly within living memory of the older generation of the cast.
