So who preemptively attacked the Mongols because they feared being able to compete with horse archers?
The Mongols' original conquest of all "people in felt tents", unifying the nomadic tribes in Mongolia and then the
Turcomens and other nomadic peoples,[

Mongol Empire to invade the
Khwarezmid Empire, and according to
Juvaini, Genghis Khan had originally sent the ruler of the Khwarezmid Empire,
Sultan Muhammad Aladdin, a message greeting him as his equal: "We now have the obligations of neighbors. Human wisdom requires that both sides walk the path of concord and observe the duties of friendship."
However, the Governor of Otrar refused to receive the mission and had all 450 of them killed, with permission from the Sultan. Upon hearing of this atrocity months later, Genghis Khan flew into a rage and used the incident as a pretext for invasion. The Mongol invasion of Central Asia however would entail the utter destruction of the Khwarezmid Empire along with the massacre of much of the civilian population of the region. According to Juvaini, the Mongols ordered only one round of slaughter in Khwarezm and Transoxiana, but systematically exterminated a particularly large portion of the people of the cities of
Khorasan. This earned the Mongols a reputation for bloodthirsty ferocity that would mark the remainder of their campaigns.
