The term "Indo-Greek" refers to the cultural and historical interactions between the ancient Greek and Indian civilizations, particularly during the period of the Indo-Greek Kingdom from the 2nd century BCE to the 1st century CE. This kingdom was established after the conquests of Alexander the Great and included parts of present-day Pakistan and North India. Indo-Greek rulers, such as Menander I, promoted the spread of Hellenistic culture, art, and philosophy in the region. They also contributed to the development of Buddhism, as many Indo-Greek coins and inscriptions reflect a blend of Greek and Indian artistic styles and religious themes.
