The Kushan Dynasty was an ancient empire that flourished in the northern regions of the Indian subcontinent from the 1st to the 3rd century CE. It was founded by the Yuezhi, a nomadic tribe, and is known for its significant contributions to trade, culture, and art. The dynasty played a crucial role in the spread of Buddhism, particularly through the patronage of rulers like Kanishka, who is often regarded as one of its most prominent emperors. Under the Kushans, the Silk Road trade flourished, connecting the East and West. This facilitated cultural exchanges and the introduction of various artistic styles, including the famous Gandhara art, which blended Greek and Indian influences. The Kushan Dynasty also established a coinage system that helped standardize trade and commerce in the region, leaving a lasting impact on the economic landscape of ancient India.
