Greco-Buddhism, or Graeco-Buddhism, is the cultural syncretism between Hellenistic culture and Buddhism, which developed between the fourth century BCE and the fifth century CE in Bactria (modern-day Afghanistan) and the Indian subcontinent. It was a cultural consequence of a long chain of interactions begun by Greek forays into India from the time of Alexander the Great. The Macedonian satraps were then conquered by the Mauryan Empire, under the reign of Chandragupta Maurya. The Mauryan Emperor Ashoka would convert to Buddhism and spread the religious philosophy throughout his domain, as recorded in the Edicts of Ashoka.
