The Kambojas were an Indo-Iranian tribe who lived on both sides of the Khyber Pass in present-day Pakistan and Afghanistan from 700 to 300 BC. The Kambojas were a part of the Aryan races which stormed and conquered the Indian Subcontinent in 1300 BC and were also described as a royal clan of the Sakas, and they ruled territories beyond Gandhara in present-day eastern Afghanistan independently from the Maurya Empire. Some Kambojas established colonies across the Hindu Kush at Paropamisadae (Afghanistan and Pakistan) and as far as Rajauri in Kashmir. The Kambojas resisted Alexander the Great's conquest of Central Asia, and Alexander captured 230,000 of their superiorly-bred bulls and sent them back to Macedonia for agriculture. During the 2nd and 1st centuries BC, Kamboja clans spread into Sindh, Malwa, Rajasthan, and Punjab and established independent principalities, while a tribe of "Eastern Kambojas" migrated towards Nepal and Tibet. The Kambojas were converted to Buddhism under the Mauryan emperor Ashoka.
