Legacy

From the 1st century AD, the Greek communities of central Asia and the northwestern Indian subcontinent 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 Western Kshatrapas. The Kalash tribe of the Chitral Valley claim to be descendants of the Indo-Greeks; although this is disputed.

It is unclear how much longer the Greeks managed to maintain a distinct presence in the Indian sub-continent. The legacy of the Indo-Greeks was felt however for several centuries, from the usage of the Greek language and calendrical methods, to the influences on the numismatics of the Indian subcontinent, traceable down to the period of the Gupta Empire in the 4th century.

The Greeks may also have maintained a presence in their cities until quite late. Isidorus of Charax in his 1st century AD "Parthian stations" itinerary described an "Alexandropolis, the metropolis of Arachosia", thought to be Alexandria Arachosia, which he said was still Greek even at such a late time:

Beyond is Arachosia. And the Parthians call this White India; there are the city of Biyt and the city of Pharsana and the city of Chorochoad and the city of Demetrias; then Alexandropolis, the metropolis of Arachosia; it is Greek, and by it flows the river Arachotus. As far as this place the land is under the rule of the Parthians.

The Indo-Greeks may also have had some influence on the religious plane as well, especially in relation to the developing Mahayana Buddhism. Mahayana Buddhism has been described as "the form of Buddhism which (regardless of how Hinduized its later forms became) seems to have originated in the Greco-Buddhist communities of India, through a conflation of the Greek Democritean – Sophistic – Pyrrhonist tradition with the rudimentary and unformalized empirical and skeptical elements already present in early Buddhism".
