Kublai Khan organized them into the Jasin guard (Alan guard) of 3,000 soldiers around 1271, along with some of the Kipchaks. The Alani guard reached its peak during the reign of Tugh Temür and their number expanded to 30,000. They remained influential in Mongolia until the 15th century, when the Oirats conquered Mongolia. During the 15-16th centuries, they formed part of the Yungshebiyu tumen in central Inner Mongolia and the Asud were large tribe of Southern Mongolia.
Today, there are few people with the clan name Asud in Ar Khorchin banner, Inner Mongolia. Mongolian Asuds live in Dundgovi and Umnugovi aimags.
