The term "Indo-Scythian" refers to a group of ancient nomadic tribes that migrated from Central Asia into the Indian subcontinent around the 2nd century BCE. They were part of the larger Scythian culture, known for their horse-riding skills and warrior lifestyle. The Indo-Scythians established several kingdoms in regions such as Gandhara and Mathura, influencing local cultures and economies. These tribes played a significant role in the history of India by facilitating trade and cultural exchange between the East and West. They are often associated with the spread of Buddhism and the introduction of new artistic styles, particularly in sculpture and coinage, which blended Hellenistic and local traditions.
