The Indo-Scythians were 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 present-day Pakistan and North India, influencing local cultures and economies. These tribes played a significant role in the spread of Buddhism and interacted with various local dynasties, including the Kushans. Their presence contributed to the cultural and political landscape of ancient India, leaving behind artifacts and inscriptions that provide insight into their way of life.
