Kushan Empire

The Kushan Empire was a powerful syncretic state that linked Central Asia, the Iranian world, and the Indian subcontinent, flourishing from roughly 30 to 375 CE.

It was created by the Kushans, one branch of the Yuezhi, a nomadic people who had migrated from the borders of China into Bactria after displacing the Greco-Bactrian kingdom. Around 30 CE the Kushan leader Kujula Kadphises united the Yuezhi tribes into a single confederation and led them in the conquest of territories across Afghanistan and into northern India, founding the empire. At its height the Kushans controlled a vast domain stretching from Central Asia through modern Afghanistan and Pakistan into the Gangetic plain of northern India, straddling the crucial overland trade routes of the Silk Road. This position made the empire enormously wealthy and a great hub of commerce and cultural exchange, connecting Rome, Persia, India, and Han China. The empire reached its zenith under Kanishka the Great (reigned c. 127–150 CE), who is celebrated for his patronage of Buddhism. Under Kanishka, Mahayana Buddhism flourished and spread from Gandhara across the mountains into Central Asia and China, and the era produced the magnificent Gandhara and Mathura schools of art, which fused Hellenistic, Persian, and Indian styles and created some of the earliest iconic images of the Buddha. The Kushans were notably tolerant and cosmopolitan, with coinage depicting Greek, Iranian, Hindu, and Buddhist deities, and they used multiple languages and scripts. From the third century the empire declined under pressure from the rising Sassanid Empire to the west, which reduced the western Kushans to vassals, and from emerging Indian powers to the east, fragmenting into smaller states before being absorbed by the expanding Gupta Empire and later the Hephthalites.
