Kushanas

The Kushan Empire (– CE) was a syncretic empire formed by the Yuezhi in the Bactrian territories in the early 1st century. It spread to encompass much of what is now Afghanistan, Eastern Iran, India, Pakistan, Tajikistan and Uzbekistan. Kushan territory in India went at least as far as Saketa and Sarnath, now near Varanasi in Uttar Pradesh, where inscriptions have been found dating to the era of the Kushan emperor Kanishka the Great.

The Kushans were most probably one of five branches of the Yuezhi confederation, an Indo-European nomadic people of possible Tocharian origin, who migrated from northwestern China (Xinjiang and Gansu) and settled in ancient Bactria. The founder of the dynasty, Kujula Kadphises, followed Iranian and Greek cultural ideas and iconography after the Greco-Bactrian tradition and was a follower of the Shaivite sect of Hinduism. Two later Kushan kings, Vima Kadphises and Vasudeva II, were also patrons of Hinduism. The Kushans in general were also great patrons of Buddhism, and, starting with Emperor Kanishka, they employed elements of Zoroastrianism in their pantheon. They played an important role in the spread of Buddhism to Central Asia and China, ushering in a period of relative peace for 200 years, sometimes described as " Pax Kushana".

The Kushans possibly used the Greek language initially for administrative purposes but soon began to use the Eastern Iranian Bactrian language. Kanishka sent his armies north of the Karakoram mountains. A direct road from Gandhara to China remained under Kushan control for more than a century, encouraged travel across the Karakoram, and facilitated the spread of Mahayana Buddhism to China. The Kushan dynasty had diplomatic contacts with the Roman Empire, Sasanian Persia, the Aksumite Empire, and the Han dynasty of China. The Kushan Empire was at the center of trade relations between the Roman Empire and China: according to Alain Daniélou, "for a time, the Kushana Empire was the centerpoint of the major civilizations". While much philosophy, art, and science was created within its borders, the only textual record of the empire's history today comes from inscriptions and accounts in other languages, particularly Chinese.

The Kushan Empire fragmented into semi-independent kingdoms in the 3rd century AD, which fell to the Sasanians invading from the west and establishing the Kushano-Sasanian Kingdom in the areas of Sogdiana, Bactria, and Gandhara. In the 4th century, the Guptas, another Indian dynasty, also pressed from the east. The last of the Kushan and Kushano-Sasanian kingdoms were eventually overwhelmed by invaders from the north, known as the Kidarites, and later the Hephthalites.

Origins

Chinese sources describe the ''Guìshuāng'' ( 貴霜, Old Chinese: ''*kuj-s aŋ''), ''i.e.'' the Kushans, as one of the five aristocratic tribes of the Yuezhi. Many scholars believe that the Yuezhi were a people of Indo-European origin. " must identify them ocharianswith the Yueh-chih of the Chinese sources... nsensus of scholarly opinion identifies the Yueh-chih with the Tokharians... e Indo-European ethnic origin of the Yuehchih = Tokharians is generally accepted... Yueh-chih = Tokharian people... Yueh-chih = Tokharians..." "They are, by almost unanimous opinion, Indo-Europeans, probably the most oriental of those who occupied the steppes." A specifically Tocharian origin of the Yuezhi is often suggested. "The identity of the Tokharoi and Yüeh-chih people is quite certain, and has been clear for at least half a century, though this has not become widely known outside the tiny number of philologists who work on early Central Eurasian and early Chinese history and linguistics." " e Tocharians have frequently been identified in Chinese historical sources as a people known as the Yuezhi..." "Pulleyblank has identified the Yuezhi... Wusun... the Dayuan... the Kangju... and the people of Yanqi... all names occurring in the Chinese historical sources for the Han dynasty, as Tocharian speakers." An Iranian, specifically Saka origin, has also been suggested by some scholars.

The Yuezhi were described in the ''Records of the Great Historian'' and the ''Book of Han'' as living in the grasslands of eastern Xinjiang and northwestern part of Gansu, in the northwest of modern-day China, until their King was beheaded by the Xiongnu (匈奴) who were also at war with China, which eventually forced them to migrate west in 176–160 BC. The five tribes constituting the Yuezhi are known in Chinese history as ''Xiūmì'' (休密), ''Guìshuāng'' (貴霜), ''Shuāngmǐ'' (雙靡), ''Xìdùn'' (肸頓), and ''Dūmì'' (都密).

The Yuezhi reached the Hellenic kingdom of Greco-Bactria (in northern Afghanistan and Uzbekistan) around 135 BC. The displaced Greek dynasties resettled to the southeast in areas of the Hindu Kush (in present-day Afghanistan and Pakistan) and the Indus basin (in present-day Pakistan and India), occupying the western part of the Indo-Greek Kingdom.

In South Asia, Kushan emperors regularly used the dynastic name ''ΚΟϷΑΝΟ'' ("Koshano") on their coinage. Several inscriptions in Sanskrit in the Brahmi script, such as the Mathura inscription of the statue of Vima Kadphises, refer to the Kushan Emperor as , ''Ku-ṣā-ṇa'' ("Kushana"). Some later Indian literary sources referred to the Kushans as ''Turushka'', a name which in later Sanskrit sources was confused with Turk, "probably due to the fact that Tukharistan passed into the hands of the western Turks in the seventh century". According to John M. Rosenfield, ''Turushka'', ''Tukhāra'' or ''Tukhāra'' are variations of the word ''Tokhari'' in Indian writings. Yet, according to Wink, "nowadays no historian considers them to be Turkish-Mongoloid or "Hun", although there is no doubt about their Central-Asian origin."

Early Kushans

Some traces remain of the presence of the Kushans in the area of Bactria and Sogdiana in the 2nd-1st century BC, where they had displaced the Sakas, who moved further south. Archaeological structures are known in Takht-i Sangin, Surkh Kotal (a monumental temple), and in the palace of Khalchayan. On the ruins of ancient Hellenistic cities such as Ai-Khanoum, the Kushans are known to have built fortresses. Various sculptures and friezes from this period are known, representing horse-riding archers, and, significantly, men such as the Kushan prince of Khalchayan with artificially deformed skulls, a practice well attested in nomadic Central Asia. Some of the Khalchayan sculptural scenes are also thought to depict the Kushans fighting against the Sakas. In these portrayals, the Yuezhis are shown with a majestic demeanour, whereas the Sakas are typically represented with side-whiskers, and more or less grotesque facial expressions.

The Chinese first referred to these people as the Yuezhi and said they established the Kushan Empire, although the relationship between the Yuezhi and the Kushans is still unclear. Ban Gu's ''Book of Han'' tells us the Kushans (Kuei-shuang) divided up Bactria in 128 BC. Fan Ye's ''Book of Later Han'' "relates how the chief of the Kushans, Ch'iu-shiu-ch'ueh (the Kujula Kadphises of coins), founded by means of the submission of the other Yueh-chih clans the Kushan Empire."

The earliest documented ruler, and the first one to proclaim himself as a Kushan ruler, was Heraios. He calls himself a "tyrant" in Greek on his coins, and also exhibits skull deformation. He may have been an ally of the Greeks, and he shared the same style of coinage. Heraios may have been the father of the first Kushan emperor Kujula Kadphises.

The Chinese ''Book of Later Han'' chronicles then gives an account of the formation of the Kushan empire based on a report made by the Chinese general Ban Yong to the Chinese Emperor :

Diverse cultural influences

In the 1st century BC, the ''Guishuang'' (Ch: 貴霜) gained prominence over the other Yuezhi tribes, and welded them into a tight confederation under commander Kujula Kadphises. The name ''Guishuang'' was adopted in the West and modified into ''Kushan'' to designate the confederation, although the Chinese continued to call them ''Yuezhi''.

Gradually wresting control of the area from the Scythian tribes, the Kushans expanded south into the region traditionally known as Gandhara (an area primarily in Pakistan's Pothowar and Khyber Pakhtunkhwa region) and established twin capitals in Kapisa (near modern Bagram) and Pushkalavati (later Charsadda
