There were several things about the Mongol Empire that were quite unique, their most surprising and advanced characteristic is that they were tolerant and actually supported outside religions. This is something that is almost never heard of in other empires of that time or any time for that matter. What is just as surprising is that many of the religions that were in the Mongol Empire hated each other and yet they fought with each other to expand the reach of the empire. For instance there were many times when Buddhists, Muslims, and Christians were fighting along side each other despite their many differences. This was one of the ways that the Mongol people kept their captured lands in peace, the Mongols did not prohibit any religion and in fact they usually promoted it among the people.
The Mongol Empire in many ways is also considered the driving force that created a unified China and Russia. So in effect the Mongols were the unifiers of two of the most powerful nations in the world today, China and Russia.
The Mongol armies were extremely successful despite being greatly outnumbered by almost every foreign army that they ever encountered.
The Mongols had many military tactics… One of the more successful employed by the was to wipe out populations that had refused to surrender
The Mongol Empire had a lasting impact, unifying large regions, some of which (such as eastern and western and the western parts of China) remain unified today
Mongols prized their commercial and trade relationships with neighboring economies and this policy they continued during the process of their conquests and during the expansion of their empire. All merchants and ambassadors, having proper documentation and authorization, traveling through their realms were protected. This greatly increased overland trade, especially the Silk Road.
During the thirteenth and early fourteenth centuries, European merchants, numbering hundreds, perhaps thousands, made their way from to the distant land of China — is only one of the best known of these. Well-traveled and relatively well-maintained roads linked lands from the Mediterranean basin to China. The Mongol Empire had negligible influence on seaborne trade. The Mongolian empire was also known for good organization and discipline.
Overall the Mongolian empire is said to be one of the worlds greatest empires, with so many achievements that many other empires could only dream of accomplishing.
