The Kambojas were a tribe of Iron Age India, frequently mentioned in Sanskrit and Pali literature. The tribe coalesced to become one of the shodhasha(sixteen) Mahajanapadas (great kingdoms) of ancient India mentioned in the Anguttara Nikaya.
The ancient Kambojas were probably of Indo-Iranian origin. They are, however, sometimes described as Indo-Aryans[page needed][volume needed] 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 parts of the Mahabharata, both of which described the Kambojas as former kshatriyas (warrior caste) who had degraded through a failure to abide by Hindu sacred rituals. Their territories were located beyond Gandharain present day eastern Afghanistan, where Buddha statues were built during the reign of Ashoka and the 3rd century BCE. The 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.[page needed]
The confederation of the Kambojas may have stretched from the valley of Rajauri in the south-western part of Kashmir to the Hindu Kush Range; in the south–west the borders extended probably as far as the regions of Kabul, Ghazni and Kandahar, with the nucleus in the area north-east of the present day Kabul, between the Hindu Kush Range and the Kunar river, including Kapisa possibly extending from the Kabul valleys to Kandahar.
Others locate the Kambojas and the Parama-Kambojas in the areas spanning Balkh, Badakshan, the Pamirs and Kafiristan. D. C. Sircar supposed them to have lived "in various settlements in the wide area lying between Punjab, Iran, to the south of Balkh." and the Parama-Kamboja even farther north, in the Trans-Pamirian territories comprising the Zeravshan valley, towards the Farghana region, in the Scythia of the classical writers.[page needed] The mountainous region between the Oxus and Jaxartes is also suggested as the location of the ancient Kambojas.
The name Kamboja may derive from (Kam + bhoj "Kamma+boja"), referring to the people of a country known as "Kum" or "Kam". The mountainous highlands where the Jaxartes and its confluents arise are called the highlands of the Komedes by Ptolemy. Ammianus Marcellinus also names these mountains as Komedas. The Kiu-mi-to in the writings of Xuanzang have also been identified with the Komudha-dvipa of the Puranic literature and the Iranian Kambojas.
The two Kamboja settlements on either side of the Hindu Kush are also substantiated from Ptolemy's Geography, which refers to the Tambyzoi located north of the Hindu Kush on the river Oxus in Bactria, and the Ambautai people on the southern side of Hindukush in the Paropamisadae. Scholars have identified both the Ptolemian Tambyzoi and Ambautai with Sanskrit Kamboja.
Scholars, such as Ernst Herzfeld, have suggested etymological links between some Indo-Aryan ethnonyms and some geonyms used by Iranian-speaking peoples of the Caucasus Mountains and Caspian basin. In particular, Kamboja somewhat resembles the hydronym Kambujiya – the Iranian name for the Iori/Gabirri river (modern Georgia/Azerbaijan). Kambujiya is also the root of Cambysene (an archaic name for the Kakheti/Balakan regions of Georgia and Azerbaijan) and the Persian personal name Cambyses. (A similar link is suggested between the Kura River, which is near the Iori, and the name of the Kurus and Kaurava mentioned in vedic literature.) Such etymologies have not, however, been universally accepted.
Kautiliya's Arthashastra and Ashoka's Edict No. XIII attest that the Kambojas followed a republican constitution. Pāṇini's Sutras tend to convey that the Kamboja of Pāṇini was a "Kshatriya monarchy", but "the special rule and the exceptional form of derivative" he gives to denote the ruler of the Kambojas implies that the king of Kamboja was a titular head (king consul) only. One king of Kamboja was King Srindra Varmana Kamboj.
The Kambojas were famous in ancient times for their excellent breed of horses and as remarkable horsemen located in the Uttarapatha or north-west. They were constituted into military sanghas and corporations to manage their political and military affairs. The Kamboja cavalry offered their military services to other nations as well. There are numerous references to Kamboja having been requisitioned as cavalry troopers in ancient wars by outside nations.
It was on account of their supreme position in horse (Ashva) culture that the ancient Kambojas were also popularly known as Ashvakas, i.e. horsemen. Their clans in the Kunar and Swat valleys have been referred to as Assakenoi and Aspasioi in classical writings, and Ashvakayanas and Ashvayanas in Pāṇini's Ashtadhyayi.
The Kambojas were famous for their horses and as cavalry-men (aśva-yuddha-Kuśalah), Aśvakas, 'horsemen', was the term popularly applied to them... The Aśvakas inhabited Eastern Afghanistan, and were included within the more general term Kambojas.
Elsewhere Kamboja is regularly mentioned as "the country of horses" (Asvanam ayatanam), and it was perhaps this well-established reputation that won for the horsebreeders of Bajaur and Swat the designation Aspasioi (from the Old Pali aspa) and assakenoi (from the Sanskrit asva "horse").
The Kambojas entered into conflict with Alexander the Great as he invaded Central Asia. The Macedonian conqueror made short shrift of the arrangements of Darius and after over-running the Achaemenid Empire he dashed into today's eastern Afghanistan and western Pakistan. There he encountered resistance from the Kamboja Aspasioi and Assakenoi tribes.
The Ashvayans (Aspasioi) were also good cattle breeders and agriculturists. This is clear from the large number of bullocks that Alexander captured from them – 230,000 according to Arrian – some of which were of a size and shape superior to what the Macedonians had known, and which Alexander decided to send to Macedonia for agriculture.
During the 2nd and 1st centuries BCE, clans of the Kambojas from Central Asia in alliance with the Sakas, Pahlavas and the Yavanas entered present Afghanistan and India, spread into Sindhu, Saurashtra, Malwa, Rajasthan, Punjab and Surasena, and set up independent principalities in western and south-western India. Later, a branch of the same people took Gauda and Varendra territories from the Palas and established the Kamboja-Pala Dynasty of Bengal in Eastern India.
There are references to the hordes of the Sakas, Yavanas, Kambojas, and Pahlavas in the Bala Kanda of the Valmiki Ramayana. In these verses one may see glimpses of the struggles of the Hindus with the invading hordes from the north-west. The royal family of the Kamuias mentioned in the Mathura Lion Capital are believed to be linked to the royal house of Taxila in Gandhara. In the medieval era, the Kambojas are known to have seized north-west Bengal (Gauda and Radha) from the Palas of Bengal and established their own Kamboja-Pala Dynasty. Indian texts like Markandeya Purana, Vishnu Dharmottari Agni Purana,
A branch of Kambojas seems to have migrated eastwards towards Nepal and Tibet in the wake of Kushana (1st century) or else Huna (5th century) pressure and hence their notice in the chronicles of Tibet ("Kam-po-tsa, Kam-po-ce, Kam-po-ji") and Nepal (Kambojadesa). The 5th-century Brahma Purana mentions the Kambojas around Pragjyotisha and Tamraliptika.[volume needed]
The Kambojas of ancient India are known to have been living in north-west, but in this period (9th century AD), they are known to have been living in the north-east India also, and very probably, it was meant Tibet.
The Kambojas find prominent mention as a unit in the 3rd-century BCE Edicts of Ashoka. Rock Edict XIII tells us that the Kambojas had enjoyed autonomy under the Mauryas.[page needed] The republics mentioned in Rock Edict V are the Yonas, Kambojas, Gandharas, Nabhakas and the Nabhapamkitas. They are designated as araja. vishaya in Rock Edict XIII, which means that they were kingless, i.e. republican polities. In other words, the Kambojas formed a self-governing political unit under the Maurya emperors.
