What happened
Chandragupta Maurya founded the Maurya Empire. He defeated the Nanda dynasty in Magadha. He raised an army, defeated Greek governors, and took control of the eastern Indus Valley. He expanded into parts of the western Indus Valley and possibly eastern Afghanistan via a marriage alliance with Seleucus I Nicator. His reign lasted c. 320–298 BCE and centred in Magadha (present-day Bihar).
How we know it
The evidence comes from a single source: a modern descriptive text titled ‘Chandragupta Maurya’, which synthesises scholarly consensus and cites contested chronologies. It does not quote contemporary inscriptions, coins, or Greek or Indian primary sources like Megasthenes’ Indica or the Arthashastra directly — only references Chanakya via the later Sanskrit play Mudrarakshasa.
Why it went that way
His rise followed the power vacuum left by Alexander’s death in 323 BCE. The Nanda dynasty was unpopular. Chandragupta mobilised military force against both Indian rivals and Greek garrisons. His alliance with Seleucus — sealed c. 305–303 BCE — converted battlefield conflict into stable territorial exchange, enabling expansion without sustained war.
What is still contested
The exact chronology remains disputed: scholars debate whether Magadha fell c. 322–319 BCE or later (c. 311–305 BCE), and whether Punjab was conquered before or after Magadha. The extent of control in eastern Afghanistan is qualified as ‘possible’. The role and historicity of Chanakya rest solely on the much-later Mudrarakshasa, not contemporary evidence.
What it changed
It replaced fragmented regional rule with a centralised empire spanning Gujarat, Magadha, and the Indus Valley. It established an extensive network of cities and trade-routes. It created the first documented Indian state to negotiate a dynastic treaty with a Hellenistic ruler — shifting geopolitical alignment from post-Alexander fragmentation toward Indo-Western diplomacy.
Is it worth your time
Yes — because it marks the first verifiable consolidation of a pan-Indian imperial state, with clear geographic scope, documented military methods, and diplomatic mechanisms. Its scale, timing, and institutional novelty make it foundational for understanding South Asian state formation — but only if treated as a documented beginning, not a mythic origin.
