Kanishka and the Kushan Empire: Saka Era of 78 CE, Fourth Buddhist Council, Gandhara and Mathura Art, and the Silk Road

The Kushans built an empire that linked India with Central Asia, China and the Roman world along the Silk Road. Their greatest king, Kanishka, patronised Buddhism, gave his name to an era that is still the basis of India's national calendar, and presided over a flowering of art in Gandhara and Mathura. This guide arranges the Kushan story for competitive exams.

From the Yuezhi to an empire

The Yuezhi were pushed westward by the Xiongnu in the 2nd century BCE and settled in Bactria (northern Afghanistan). One of their five clans, the Kushana, united the others under Kujula Kadphises in the 1st century CE. He extended rule into Kabul and Gandhara. His successors, Vima Takto and Vima Kadphises, pushed into the Indian plains. Vima Kadphises issued abundant gold coins, many with the figure of Shiva and the bull, showing his devotion to Shaivism.

The Rabatak inscription, written in Bactrian using Greek letters, gives the family tree of Kanishka and names the cities under his control, from Afghanistan to Pataliputra and Champa in the Gangetic plain.

Kanishka's empire

Kanishka ruled a vast realm stretching from Central Asia and Afghanistan through Gandhara, Kashmir and Punjab to Mathura and possibly as far east as Varanasi. His statues, coins and inscriptions show him as a powerful warrior-king — the headless statue of Kanishka at Mat near Mathura, wearing a long coat and boots, is one of the best-known Kushan sculptures.

Chinese sources record wars between the Kushans and the Chinese general Ban Chao in Central Asia; the Kushans controlled important stretches of the Silk Road, profiting from trade between China, India and Rome.

The Saka era (78 CE)

The era that began with Kanishka's accession in 78 CE is known as the Saka era (Shaka Samvat). It was later used widely by Saka and other rulers, which explains the name.

The Indian National Calendar, adopted in 1957 on the recommendation of the Calendar Reform Committee headed by Meghnad Saha, is based on the Saka era. Its first month is Chaitra, beginning on 22 March (21 March in leap years).

Kanishka and Buddhism

Scholars at his court

Scholar Known for
Ashvaghosha Buddhacharita, a poetic life of the Buddha

Charaka Charaka Samhita, a classic of Ayurveda; by tradition Kanishka's physician

Kushan art: Gandhara and Mathura

The Kushan period saw the first images of the Buddha in human form, made in two great schools:

Feature Gandhara school Mathura school
Region North-west (Peshawar, Taxila, Swat) Mathura, Uttar Pradesh
Influence Greco-Roman (Hellenistic) Indigenous Indian
Material Grey or blue-grey schist, stucco Red spotted sandstone
Buddha's appearance Wavy hair, heavy folded robes, spiritual calm Shaven or snail-shell curls, smiling, energetic
Themes Mostly Buddhist Buddhist, Jain and Hindu

A third school, Amaravati, flourished in the Andhra region under the Satavahanas around the same time.

Coinage and economy

The Kushans issued the largest number of gold coins in ancient India up to their time, many matching the weight of the Roman aureus. Coins carried deities of many traditions — Greek (Helios), Iranian (Mithra, Ardochsho), Indian (Shiva/Oesho) and the Buddha (Boddo) — reflecting a multicultural empire. Trade with Rome brought gold into India, a fact noted in Roman complaints about the drain of Roman wealth to the East.

Decline

After Huvishka and Vasudeva I (whose name shows Indian influence), Kushan power declined in the 3rd century CE, squeezed by the Sasanian Persians in the west and regional Indian powers. The Guptas later rose in the Gangetic plain.
