The legacy of the Indo-Greeks starts with the formal end of the Indo-Greek Kingdom from the 1st century, as 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 Western Kshatrapas. It is unclear how much longer the Greeks managed to maintain a distinct presence in the Indian sub-continent.
