Yuezhi in the context of "Nomadic pastoralists"

The Kushan Empire (c. 30–c. 375 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, Western Nepal, 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. Many of the later Kushan kings after Kujula, were also patrons of Hinduism, including (but not limited to) Vima Kadphises and Vasudeva II. 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 Xiongnu (Chinese: 匈奴, [ɕjʊ́ŋ.nǔ]) were a tribal confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Eurasian Steppe from the 3rd century BC to the late 1st century AD. Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.

After overthrowing their previous overlords, the Yuezhi, the Xiongnu became the dominant power on the steppes of East Asia, centred on the Mongolian Plateau. The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and Xinjiang. Their relations with the Chinese dynasties to the south-east were complex—alternating between various periods of peace, war, and subjugation. Ultimately, the Xiongnu were defeated by the Han dynasty in a centuries-long conflict, which led to the confederation splitting in two, and forcible resettlement of large numbers of Xiongnu within Han borders. During the Sixteen Kingdoms era, listed as one of the "Five Barbarians", their descendants founded the dynastic states of Han-Zhao, Northern Liang and Helian Xia and during the Northern and Southern dynasties founded Northern Zhou (founded by members of the Yuwen tribe of Xiongnu origin) in northern China.

Kujula Kadphises (Kushan language: Κοζουλου Καδφιζου, also Κοζολα Καδαφες; Kharosthi: 𐨐𐨂𐨗𐨂𐨫 𐨐𐨯, IAST: Ku-ju-la Ka-sa, Kujula Kasa; Chinese: 丘就卻; pinyin: Qiūjiùquè; r. 30–80 CE, or 40–90 CE according to Bopearachchi. 25–85 CE as per Benjamin.) was a Kushan prince who united the Yuezhi confederation in Bactria during the 1st century CE, and became the first Kushan emperor. According to the Rabatak inscription, he was the great grandfather of Kanishka I. He is considered the founder of the Kushan Empire.

Kangju (Chinese: 康居; pinyin: kāngjū; Wade–Giles: K'ang-chü; Eastern Han Chinese: kʰɑŋ-kɨɑ < *khâŋ-ka (c. 140 BCE)) was the Chinese name of a kingdom in Central Asia during the first half of the first millennium CE. The name Kangju is now generally regarded as a variant or mutated form of the name Sogdiana. According to contemporaneous Chinese sources, Kangju was the second most powerful state in Transoxiana, after the Yuezhi. Its people, known in Chinese as the Kāng (康), were evidently of Indo-European origins, spoke an Eastern Iranian language, and had a semi-nomadic way of life. The Sogdians may have been the same people as those of Kangju and closely related to the Sakas, or other Iranian groups such as the Asii.

Artificial cranial deformation or modification, head flattening, or head binding is a form of body alteration in which the skull of a human being is deformed intentionally. It is done by distorting the normal growth of a child's skull by applying pressure. Flat shapes, elongated ones (produced by binding between two pieces of wood), rounded ones (binding in cloth), and conical ones are among those chosen or valued in various cultures.

Typically, the alteration is carried out on an infant, when the skull is most pliable. In a typical case, head binding begins approximately a month after birth and continues for about six months.

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.

The invasion of India by the Huna peoples follows invasions of the subcontinent in the preceding centuries by the Yavana (Indo-Greeks), the Saka (Indo-Scythians), the Pahlava (Indo-Parthians), and the Kushana (Yuezhi). The Alchon Empire was the second of four major Huna states established in Central Asia and the Indian subcontinent. The Alchon were preceded by the Kidarites and succeeded by the Hephthalites and Nezak Huns in Bactria and the Hindu Kush respectively. The names of the Alchon kings are known from their extensive coinage, Buddhist accounts, and a number of commemorative inscriptions throughout the Indian subcontinent.

The Wusun (/ˈwuːsʌn/ WOO-sun) were an ancient semi-nomadic steppe people mentioned in Chinese records from the 2nd century BC to the 5th century AD.

The Wusun originally lived between the Qilian Mountains and Dunhuang (Gansu) near the Yuezhi. Around 176 BC the Xiongnu raided the lands of the Yuezhi, who subsequently attacked the Wusun, killing their king and seizing their land. The Xiongnu adopted the surviving Wusun prince and made him one of their generals and leader of the Wusun. Around 162 BC the Yuezhi were driven into the Ili River Valley in Zhetysu, Dzungaria and Tian Shan, which had formerly been inhabited by the Saka. The Wusun then resettled in Gansu as vassals of the Xiongnu. In 133–132 BC, the Wusun drove the Yuezhi out of the Ili Valley and settled the area.

The Asii, Osii, Ossii, Asoi, Asioi, Asini or Aseni were an ancient Indo-European people of Central Asia, during the 2nd and 1st centuries BCE. Known only from Classical Greek and Roman sources, they were one of the peoples held to be responsible for the downfall of the Greco-Bactrian Kingdom. In Greek Mythology they were the children of Iapetus and Asia.

Modern scholars have attempted to identify the Asii with other peoples known from European and Chinese sources including the: Yuezhi, Tocharians, Issedones/Wusun and/or Alans.
