Question

How did western europe maintain order and stability even with an absence of a durable centralized empire?

Answer 1

I love when people post their homework questions.  What makes you think that europe didn't have a centralised empire????  One must look at the roman empire for getting the whole ball of wax  going but also you have to look at  the church for keeping it going.

There is your start now its up to you to figure if I blowing smoke or have given you a starting point.
