The Indo-Greeks were a group of Hellenistic rulers who established a kingdom in the northwestern regions of the Indian subcontinent around the 2nd century BCE. They emerged after the decline of the Maurya Empire and were influenced by both Greek and Indian cultures. Their reign is notable for the spread of Greek art and Buddhism, as well as the introduction of coinage that featured Greek inscriptions. The most famous Indo-Greek king was Menander I, who is often associated with the spread of Buddhism in the region. The Indo-Greek period is marked by a unique blend of Greek and Indian traditions, which can be seen in their architecture, sculpture, and religious practices.
