Europe in the Post Classical period lays the foundation for the Europe that will come to dominate world affairs. If you are picking a period where Europe (and specifically Western Europe) is the least important in World History, this may be it. Medieval Europe refers to the time between the fall of Rome and the reemergence of Europe during the Early Modern Period around the 15th Century. Although not as important as Muslims, Mongols, or the Chinese in the period, it remains foundational to understand them in the next few periods into the 21st Century.
