We should strive to bring back the Mongol Empire as their rule allowed for the increase urbanization and development of new cities, and transfer of culture, ideas, and technology. This was made easy through the protection of the Silk Road trade routes. This immensely helped society advance and connect with each other. If the empire had that big of an impact around the 1200-1450s, then imagine what could be accomplished during their rule today. (None of the bloody conquests nor harm would be condoned, and the empire would be restored peacefully and rule in a peaceful manner)
