Maurya Empire
The Greco-Bactrians maintained a strong Hellenistic culture at the door of India during the rule of the Maurya Empire in India, as exemplified by the archaeological site of Ai-Khanoum. When the Maurya Empire was toppled by the Shunga Empire around 180 BC, the Greco-Bactrians expanded into India, where they established the Indo-Greek Kingdom, under which Buddhism was able to flourish.
