The Kushan Empire was a significant ancient empire that flourished from the 1st to the 3rd century CE in parts of present-day India, Pakistan, and Afghanistan. It was known for its cultural diversity and played a crucial role in the spread of Buddhism along the Silk Road, facilitating trade and cultural exchange between the East and West. The empire was established by the Yuezhi people and reached its peak under the rule of Kanishka, who is often credited with promoting art, religion, and commerce. The Kushan rulers issued coins that depicted various deities, reflecting the empire's rich cultural tapestry and its influence on subsequent civilizations in the region.
