During the post-classical era, the Mongol empire was civilized because it had an extensive system of organization for its processes and its promotion of trade & arts its region. However, it was also uncivilized because the Mongol empire, during its conquests, had slaughtered many people needlessly. The Mongol empire was civilized because of an organized system of processes.
