175 BCE
Demetrius, king of the Greco-Bactrian state, may have been as far as the imperial capital Pataliputra in eastern India (today Patna).
However, these campaigns are typically attributed to Menander.
The invasion is completed by 175 BCE.
This establishes in northern India what is called the Indo-Greek Kingdom, which is to last for almost two centuries until around CE 10.
The Buddhist faith flourishes under the Indo-Greek kings, foremost among them Menander I.
It is also a period of great cultural syncretism, exemplified by the development of Greco-Buddhism.
