Greco-Buddhism (or Græco-Buddhism) was the syncretism between the culture of Classical Greece and Buddhism in the then Gandhara region of modern Afghanistan and Pakistan, between the 4th century BCE and the 5th century CE.[26] It influenced the artistic development of Buddhism, and in particular Mahayana Buddhism, before it spread to central and eastern Asia, from the 1st century CE onward. Demetrius (son of the Greco-Bactrian king Euthydemus) invaded northern India in 180 BCE as far as Pataliputra and established an Indo-Greek kingdom. To the south, the Greeks captured Sindh and nearby coastal areas, completing the invasion by 175 BCE and confining the borders of Sunga's (Magadha Empire) to the east. Meanwhile, in Bactria, the usurper Eucratides killed Demetrius in a battle. Although the Indo-Greeks lost part of the Gangetic plain, their kingdom lasted nearly two centuries
