Mongols ruled almost the known world. In middle east, that Included the destruction of baghdad. But they need grazing land for their horses snd sheeps. No grazing land, no conquest.mongols never ruled middle eastern region long
beaten back handsomely
good example is battle of ayn jalut
and many more
it's like some pirates taking over some port temporarily
won't last, didn't last
nomadic lifestyle can't win over sedentary civilizations with loooong history
Muslims been in tiongkok since the earliest days 7th century christian era i think
in canton got grave of many arab muslims from that era
incl Prophet's uncle, i believe
it's jewish commie ideology that's alien to tiongkok
The mongols retreat mostly due to the death of their leader or mongol civil war only to re invade next few years until eventually most of them became muslims and settled.
