The Kushanas were an ancient empire that thrived in the northern regions of the Indian subcontinent from the 1st to the 3rd century CE. They are known for their significant contributions to trade, culture, and art, particularly through the spread of Buddhism and the development of the Gandhara art style, which blended Greek and Indian influences. The Kushana rulers, including the famous Kanishka, expanded their territory across present-day India, Pakistan, and Afghanistan. They established a vast trade network along the Silk Road, facilitating cultural exchange and economic prosperity. The Kushanas played a crucial role in the history of ancient India, influencing various aspects of society and religion.
