What two nomadic groups are from Central Asia?
Nomadic groups in Central Asia included the Huns and other Turks
The last edit was super wrong. The answer is Theravada and Mahayana. Those were the two Buddhist groups that spread Buddah's ideas to Southeast Asia. Then, Buddah's idea was adopted in Ceylon and Sri Lanka. They are described as cities, not as the name of the groups that spread Siddharta's idea. That answer from the last person? He or she needs help.
