Kushan Empire

From 130 BCE, the Scythians and then the Yuezhi, following a long migration from the border of China, started to invade Bactria from the north. Around 125 BCE the Greco-Bactrian king Heliocles, son of Eucratides, was probably killed during the invasion and the Greco-Bactrian kingdom proper ceased to exist. Heliocles may have been survived by his relative Eucratides II, who ruled south of the Hindu Kush, in areas untouched by the invasion. Other Indo-Greek kings like Zoilos I, Lysias and Antialcidas may possible have been relatives of either the Eucratid or the Euthydemid dynasties; they struck both Greek and bilingual coins and established a kingdom of their own. In addition to the worship of the Classical pantheon of the Greek deities found on their coins Zeus, Herakles, Athena, Apollo, the Indo-Greeks were involved with local faiths, particularly with Buddhism, but also with Hinduism and Zoroastrianism.

The name Kushan derives from the Chinese term Guishang, used in historical writings to describe one branch of the Yuezhi—a loose confederation of Indo-European people who had been living in northwestern China until they were driven west by another group, the Xiongnu, in 176–160 B.C. The Yuezhi reached Bactria (northwest Afghanistan and Tajikistan) around 135 B.C. Gradually wresting control of the area from the Scytho-Parthians, the Yuezhi moved south into the northwest Indian region traditionally known as Gandhara (now parts of Pakistan and Afghanistan) and established a capital near Kabul.

The Sakas settled in areas of southern Afghanistan, still called after them Sakastan. From there, they progressively expanded into the Indian subcontinent, where they established various kingdoms, and where they are known as Indo-Scythians.

In Parthia, between 138-124 BCE, the Sakas tribes (Sai) of the Massagetae and Sacaraucae came into conflict with the Parthian Empire, winning several battles, and killing successively king Phraates II and king Artabanus I. The Parthian king Mithridates II finally retook control of Central Asia, first by defeating the Yuezhi in Sogdiana in 115 BCE, and then defeating the Scythians in Parthia and Seistan around 100 BCE. After the death of Azes II, the rule of the Indo-Scythians in northwestern India finally crumbled with the conquest of the Kushans, one of the five tribes of the Yuezhi who had lived in Bactria for more than a century, and were now expanding into India to create a Kushan Empire. Soon after, the Parthians invaded from the west. Their leader Gondophares temporarily displaced the Kushans and founded the Indo-Parthian Kingdom that was to last towards the middle of the 1st century CE. The Kushans ultimately regained northwestern India from around 75 CE, and the area of Mathura from around 100 CE, where they were to prosper for several centuries. The Western king Philoxenus briefly occupied the whole remaining Greek territory from the Paropamisadae to Western Punjab between 100 to 95 BCE, after what the territories fragmented again. The eastern kings regained their territory as far west as Arachosia.

Around 80 BCE, an Indo-Scythian king named Maues, possibly a general in the service of the Indo-Greeks, ruled for a few years in northwestern India before the Indo-Greeks again took control. King Hippostratos (65-55 BCE) seems to have been one of the most successful subsequent Indo-Greek kings until he lost to the Indo-Scythian Azes I, who established an Indo-Scythian dynasty.

Throughout the 1st century BCE, the Indo-Greeks progressively lost ground against the invasion of the Indo-Scythians. Although the Indo-Scythians clearly ruled militarily and politically, they remained surprisingly respectful of Greek and Indian cultures, continued to rule a territory in the eastern Punjab, until the kingdom of the last Indo-Greek king Strato II was taken over by the Indo-Scythian ruler Rajuvula around 10 CE.

From the 1st century CE, the Greek communities of central Asia and northwestern India lived under the control of the Kushan branch of the Yuezhi, apart from a short-lived invasion of the Indo-Parthian Kingdom. The Kushans founded the Kushan Empire, which was to prosper for several centuries.

In the south, the Greeks were under the rule of the (Sakas) Western Kshatrapas. Altogether, there were 27 independent Kshatrapa rulers during a period of about 350 years. The first Kshatrapas ruled parts of northwestern India as far as Mathura and may have been viceroys of the Kushans. Eventually they became independent as they vanquished the Satavahana empire, but retained the name of Kshatrapas. Satavahana kings ruled much of Deccan plateau between 50 B.C. to 250 A.D.

Kushan Empire

The Western Kshatrapas, or Western Satraps, (35-405 CE) were Saka rulers of the western and central part of India (Saurashtra and Malwa: modern Gujarat, Maharashtra, Rajasthan and Madhya Pradesh states). They were contemporaneous with the Kushans who ruled the northern part of the Indian subcontinent, and the Satavahana (Andhra) who ruled in Central India. The Kshatrapas established their own calendar, which starts in 78 CE and defines the beginning of the Saka era, and which today the starting yeare for the official calendar of the Indian Republic, is used with Hindu calendars, the Indian national calendar, and the Cambodian Buddhist calendar. The Kshatrapas established their own calendar, which starts in 78 CE and defines the beginning of the (Shalivahana era) Saka era.
