Alchon Huns
The Alchon Huns, (Bactrian: αλχον(ν)ο Alkhon(n)o or αλχαν(ν)ο Alkhan(n)o) also known as the Alkhan, Alchono, Alxon, Alkhon, Alakhana, and Walxon, were a nomadic people who established states in Central Asia and the Indian subcontinent during the 4th and 6th centuries CE. They were first mentioned as being located in Paropamisus, and later expanded south-east, into the Punjab and Central India, going as far as Eran and Kausambi. The Alchon invasion of the Indian subcontinent eradicated the Kidarite Huns who had preceded them by about a century, and contributed to the fall of the Gupta Empire, in a sense bringing an end to Classical India.
