The Kushans were an ancient empire that flourished in Central Asia from the 1st to the 3rd century CE. They originated from the Yuezhi, a nomadic group, and established their rule over a vast territory that included parts of modern-day India, Pakistan, and Afghanistan. The Kushans played a significant role in trade along the Silk Road, facilitating cultural and economic exchanges between the East and West. Under the reign of Kanishka, one of their most notable emperors, the Kushans promoted the spread of Buddhism and supported the arts. They are known for their unique coinage and the development of a syncretic culture that blended various influences, including Greek, Persian, and Indian traditions.
