📖 ~13 min read 🏺 Ancient Indian History

Introduction

Following the Mauryan Empire's decline (c. 185 BCE), India fragmented into several regional kingdoms — some indigenous (Shunga, Kanva, Satavahana), others founded by successive waves of Central Asian invaders (Indo-Greeks, Shakas, Parthians, Kushanas) — until the rise of the Gupta Empire restored large-scale political unity in the 4th century CE.

Significance of the Post-Mauryan Period

  • Despite political fragmentation, this era saw vibrant cultural syncretism — Indo-Greek, Persian, and Central Asian influences blended with indigenous traditions, especially visible in the Gandhara school of art (Greco-Buddhist sculpture).
  • Flourishing Indo-Roman trade, especially under the Satavahanas, with Roman gold coins found across South India.
  • Mahayana Buddhism emerged as a distinct school during the Kushana period, introducing Bodhisattva worship and idol veneration of the Buddha — a major shift from earlier aniconic traditions.
📌 Saka Era: Kanishka's Saka Era (started 78 CE) remains in official use in India today as one of the two calendars (alongside the Gregorian) for government purposes — the Indian national calendar.
