During the 13th and 14th century the Mongolian empire became histories largest contiguous empire. Led by Chinggis Haan and his many sons and their sons after that they were able to crush civil war between the Mongol empires and came to a mutual understanding of who was king. The only way Temujin seized his seat on the throne was to kill everyone who opposed his claim. Born with blood in his grip and killed his elder brother in cold blood he was destined to become a fearsome leader. He introduced a new sorting system for the armies which was based on headcounts and leaders among small groups led by bigger leaders of smaller groups and so on(soldier to head of ten to head of hundred to head of thousand to all the way up to the king himself) . The knowledge they gained from invading foreign countries was an extreme asset to further invasions of the western kingdoms. The people who were seized from the previous invasions were kept alive and accepted as civilians so long as they provide them the answers they were looking for. The captive soldiers were offered a spot in their conquest and fight under a pagan flag. Therefor the Mongolians would not have risk their main army to capture small cities. Not all of the captive soldiers were placed on the same tenths in order to avoid risks of deserters or betrayals.

During this conflict they supported trades from the silk road and the trade influence flourished under the safety of Mongolian armies claimed more and more land following the silk road from the heart of Europe all the way out to  Gulf of the Yellow Sea.

Across this wide country they used the same script to deliver out important messages to high seated heads across the country. They also invented an efficient mailing system on horseback, where they reach a certain point during their journey and switch horses, eat, sleep or even switch mailmen in order to deliver urgent messages.

Since the Mongolian Empire saw the high ethnicities of foreign countries an asset they were treated a bit better than slaves but not better than Mongolians themselves. They allowed multiple beliefs of religion and race to coexist in peace. They did not try to convert them to their pagan ways. In fact the Mongolian Script that they use was founded on the battle field.

Fearing his great power small countries in the southern Asia gave wives to Chinggis and begged to be apart of their conquest. It is said that 1 in 200 men are decedents of Chinggis which is more than 16 million men. Who knows? You might be one of them!
