BharatNotes What is Kushan Empire and Kanishka?
The Kushan Empire was a major power of the early centuries CE, built by the Kushans, one branch of the Yuezhi — a nomadic, probably Tocharian (Indo-European) people who migrated from northwestern China (Gansu/Xinjiang) into Bactria. There, Kujula Kadphises united the Yuezhi tribes in the 1st century CE and became the first Kushan emperor. The empire's most celebrated ruler was Kanishka I, whose reign is now generally dated to begin around 127 CE (per Harry Falk's research, replacing the older 78 CE estimate) and lasted roughly 23 years.
Rulers and Coinage
| Ruler | Significance |
|---|---|
| Kujula Kadphises | Founder; united the Yuezhi in Bactria; followed Greco-Bactrian/Iranian iconography |
| Vima Kadphises | First to introduce gold coinage (alongside copper/silver); gold largely from Roman trade |
| Kanishka I (c. 127 CE) | Greatest ruler; empire at its zenith; patron of Buddhism and art |
| Vasudeva I (c. 191–225 CE) | Last of the "Great Kushans"; decline followed Sasanian invasions |
The Rabatak inscription (found in northern Afghanistan, in the Bactrian language) records Kanishka's titles Maharajadhiraja ("King of Kings") and Devaputra ("Son of God") and his control over much of northern India, south to Ujjain and east beyond Pataliputra. The twin capitals were Purushapura (modern Peshawar) and Mathura.
Kanishka, Buddhism and Art
Kanishka is remembered above all as a great patron of Mahayana Buddhism. He is traditionally credited with convening the Fourth Buddhist Council in Kashmir, a turning point associated with the consolidation of Mahayana doctrine. His court hosted eminent scholars:
- Ashvaghosha — author of the Buddhacharita
- Nagarjuna — Mahayana philosopher
- Vasumitra and Parsva — Buddhist scholars
- Charaka — celebrated authority on Ayurveda (court physician)
The Kushan period saw two great schools of sculpture flourish: the Gandhara school, which produced the first images of the Buddha in human form and shows strong Greco-Roman influence, and the indigenous Mathura school, carved in red sandstone. The Kushans' position on the Silk Road made them central to Indo-Roman trade and the transmission of Buddhism into Central Asia and China.
Decline
After Vasudeva I, the empire weakened. The rise of the Sasanians of Persia (from around 240 CE onward) led to the establishment of the Kushanshahs (Indo-Sasanians) in the northwest, while in India Gupta expansion — including pressure from Samudragupta — finished off the surviving Kushan remnants.
UPSC Angle
For Prelims, anchor the high-yield facts: Yuezhi origin, Kujula Kadphises as founder, Vima Kadphises as the first gold-coin issuer, Kanishka and the Fourth Buddhist Council, and his court scholars. For GS1 art-and-culture and Mains, link the Kushans to the Gandhara–Mathura artistic synthesis, the spread of Mahayana Buddhism, and Silk Road trade — a foundation concept underpinning several ancient-history question families.
