Kanishka the Great: Kushan Emperor, Buddhist Patron, and Conqueror

Kanishka I (reigned c. 127–150 CE) was the greatest Kushan emperor, expanding the empire from Central Asia to northern India and patronizing Buddhism's Mahayana transformation.

Key Achievements

• Buddhist patronage: Convened Fourth Buddhist Council (Kashmir/Jalandhar) — codified Mahayana texts, commissioned Gandharan art (Greco-Buddhist synthesis).
• Coinage: Bilingual (Greek/Bactrian); first to depict Buddha in human form; Zoroastrian, Hellenistic, Indian deities — reflects religious pluralism.
• Infrastructure: Cities, monasteries, stupas (Kanishka Stupa, Peshawar — tallest ancient structure).
• Calendar: Kanishka era (Saka era) — year 1 = 78 CE; still used in Indian national calendar.
