The term "Kushana" refers to a historical empire that existed in the northern regions of the Indian subcontinent during the first few centuries CE. The Kushana Empire is known for its significant cultural and economic influence, as well as its role in the spread of Buddhism. The empire was established by the Kushans, a nomadic tribe originally from Central Asia. The Kushana rulers, particularly Kanishka, are noted for their patronage of the arts and religion. They facilitated trade along the Silk Road, connecting India with Central Asia and beyond. This interaction led to a rich exchange of ideas, art, and culture, contributing to the development of the region during this period.
