The Kambojas were a tribe of Iron Age India, frequently mentioned in Sanskrit and Pali literature.
The ancient Kambojas were probably of Indo-Iranian origin. They are, however, sometimes described as Indo-Aryans and sometimes as having both Indian and Iranian affinities. The Kambojas are also described as a royal clan of the Sakas.
The earliest reference to the Kambojas is in the works of Pāṇini, around the 5th century BCE. Other pre-Common Era references appear in the Manusmriti (2nd century) and the Mahabharata (1st century), both of which described the Kambojas as former kshatriyas who had degraded through a failure to abide by Hindu sacred rituals. Their territories were located beyond Gandhara, beyond Pakistan, Afghanistan laying in Tajikistan, Uzbekistan, Kyrgyzstan where Buddha statues were built in the name of king Maurya & Ashoka and the 3rd century BCE Edicts of Ashoka refers to the area under Kamboja control as being independent of the Mauryan empire in which it was situated.
Some sections of the Kambojas crossed the Hindu Kush and planted Kamboja colonies in Paropamisadae and as far as Rajauri. The Mahabharata locates the Kambojas on the near side of the Hindu Kush as neighbors to the Daradas, and the Parama-Kambojas across the Hindu Kush as neighbors to the Rishikas (or Tukharas) of the Ferghana region.
