Since you'd keep the social structure "mostly the same," your objective in overthrowing the existing government appears to be merely replacing the old boss with the new boss - yourself.

Yes, but with the overthrow of Caesar Augustus, a lot of that history would no longer exist.

Any such p has to divide the resultant of f(x) and g(x). If no prime factor of the resultant provides a solution, there isn't one.

EDIT: I am assuming that gcd(a, b, c) = gcd(A, B, C) = 1.
