Does EB have to end in 14AD?

I read that Europa Barbarorom (v.1.2) is scripted to end in 14AD. Assuming that I make it that far into the game, is there some way to prolong it beyond that time?

I feel certain that this question has already been asked and answered by somebody, but I have not been able to yet find the answer in my searches, so perhaps somebody of repute could share the answer with me, or direct me to it?
