Overview
Silk Road facilitators; Gandhara art and Buddhism patronage
Kushan dynasty
Imperial dynasty founded by Kujula Kadphises who united the five Yuezhi tribes in Bactria. The Kushans built a vast Silk Road empire spanning Bactria, Gandhara, and the upper Gangetic plain, peaking under Kanishka I (c. 127-150 CE). Greatest royal patrons of Mahayana Buddhism and the Gandhara art school. Ended under pressure from the Sassanids in the west and the Guptas in the east.
Territory Phases
Kushan Empire (Founding)30 BCE – 95 CE
Founding phase under Kujula Kadphises, who united the five Yuezhi tribes in Bactria around the 1st century CE. Inherited the former Greco-Bactrian and Indo-Parthian territories. Early Kushan coins imitated Greek Hellenistic styles; administration combined Iranian and Indian practices.
Kushan Empire (Expansion)90 CE – 120 CE
Expansion under Vima Kadphises — extended Kushan rule deep into northwest India (Gandhara, Punjab, Sindh). Introduced gold coinage based on the Roman aureus standard, indicating intensifying Silk Road trade. Displaced the last Indo-Parthians (Pahlavas) from Gandhara.
Kushan Empire (Kanishka Peak)115 CE – 170 CE
Peak Kushan Empire under Kanishka I (c. 127-150 CE) and immediate successors. Maximum extent spans Bactria, Sogdiana, Gandhara, Punjab, and the upper Gangetic plain as far east as Varanasi. Capital at Purushapura (Peshawar) with Mathura as a second imperial center. Kanishka convened the Fourth Buddhist Council and was the greatest royal patron of Mahayana Buddhism. The Gandhara art school flourishes — synthesizing Greek, Iranian, and Indian forms.
Kushan Empire (Huvishka-Vasudeva)165 CE – 230 CE
Mature Kushan period under Huvishka (c. 150-190 CE) and Vasudeva I (c. 190-230 CE). Continued vast territorial extent with slight contraction at the eastern Gangetic edge. Coinage diversifies with Hindu deities (Shiva, Vishnu) alongside Buddha and Iranian gods. Silk Road trade peaks; Kushan envoys reach Han China and Rome.
Kushan Empire (Sassanid pressure)224 CE – 275 CE
Under pressure from the rising Sassanid Persian Empire (Ardashir I and Shapur I). Bactria and eastern Iran fall to Sassanid invasions; the western Kushan territories become the Kushano-Sasanian (Kushanshahs) vassal kingdom. Indian territories continue under 'Eastern Kushan' rulers.
Kushan Empire (Late / Eastern)270 CE – 375 CE
Late Kushan period — reduced to Gandhara and the upper Indus region. Lost most of Bactria to the Sassanids. Survived as a local power in northwest India until absorbed by the rising Gupta Empire and the Kidarite Huns in the late 4th century CE.

Key Events
Rabatak inscription of Kanishka I127 CE
Rabatak, Afghanistan
Bactrian-language inscription in Greek script discovered 1993 at Rabatak, Afghanistan. Records Kanishka I's genealogy (listing Kujula Kadphises, Vima Takto, and Vima Kadphises), his conquests as far as Pataliputra and Champa, and his patronage of Buddhist sanctuaries. First published by Sims-Williams & Cribb 1996. The single most important primary source for Kushan chronology.
Fourth Buddhist Council under Kanishka127 CE
Kashmir
Buddhist council convened by Kanishka I in Kashmir, traditionally regarded as a landmark event in the codification and spread of Mahayana Buddhism. Attended by 500 monks under the presidency of Vasumitra; commentaries on the Abhidharma were reportedly engraved on copper plates. The historicity of the council is debated but the tradition is well-attested in Chinese pilgrim accounts (Xuanzang).
Death of Kanishka I150 CE
Purushapura (Peshawar)
Kanishka I died c. 150 CE. Chinese sources (Hou Hanshu) report he was killed by his own officers during a military campaign. His death marked the end of the Kushan Empire's most dynamic phase of expansion and Buddhist patronage.
Sassanid conquest of Bactria230 CE
Bactra (Balkh)
The Sassanid Empire under Ardashir I and later Shapur I conquered Kushan Bactria, establishing the Kushano-Sasanian vassal kingdom. This split the Kushan Empire into a western half under Sassanid suzerainty and an eastern remnant in Gandhara and the Punjab.
