I would say all of the above except the last option. "Dirty conditions led to disease "
Mongol leader Genghis Khan (1162-1227) rose from humble beginnings to establish the largest land empire in history. After uniting the nomadic tribes of the Mongolian plateau, he conquered huge chunks of central Asia and China. ... Genghis Khan died in 1227 during a military campaign against the Chinese kingdom of Xi Xia.
Unifying the Mongols was no small achievement — it meant bringing together a whole series of disparate tribes. Economically the tribal unit was optimal for a pastoral-nomadic group, but Chinggis brought all the tribes together into one confederation, with all its loyalty placed in himself.
Hope this helps !
Have a great day! :)
