During the post-classical era of ancient history, many different civilizations coexisted throughout much of the then-known world. Many of the ruling empires in that period had textbook-worthy advancements and their fair share of conflicts, however none would create such an impact on all parts of the world as the Mongols did. The Mongols, originally a nomadic group who settled the steppes of Central Asia, began the greatest conquest in recorded history during the 13th century. By the end of their reign, the Mongols acquired a vast area of ​​territory that stretched between continents and also earned a reputation as barbarians. A rough way to think of barbarians would be that they are uncivilized people who lack culture, respect, and moral standards. Although many might argue that the Mongols were true barbarians due to the cruelty of their military tactics, the Mongols were in fact thoroughly civilized due to their contributions to innovations that improved trade and the revival of laws that helped create better conditions of life for civilians with ideas of tolerance and security. Overall, the Mongols rebuilt the foundation of peace and stability in the conquered areas. Due to the cruel fighting tactics of the Mongols, some may argue that the Mongols were absolute barbarians. For example, in his account of the Nishapur massacre, the Persian chronicler Juvaini states that the Mongols had killed the people and sacked the city, leaving everything in ruins (doc 4).

Contrary to popular belief, the Mongols did in fact have a culture enriched by trade and showed a level of mutual respect through their codes of conduct. Furthermore, although it may seem that the Mongols had no standard morality resulting from their cruel battle tactics, in fact they did as they demonstrated this with their laws against theft and adultery. All of this suggests that the Mongols were far from being barbarians as many claim in history and instead of wreaking havoc during that period, they helped create a solid foundation of peace and stability..
