The Kushan rulers were a dynasty that emerged in the 1st century CE in the region of present-day Afghanistan and northern India. They played a significant role in the spread of Buddhism and facilitated trade along the Silk Road, connecting the East and West. The Kushans are known for their cultural and artistic achievements, particularly in sculpture and coinage. Under the leadership of notable rulers like Kanishka, the Kushan Empire expanded its territory and influence. They established a diverse society that included various ethnic groups and religions, promoting a rich cultural exchange. The Kushan period is often regarded as a golden age for art and commerce in ancient India.
