Historical Trajectory
Phase I: Rise
Chandragupta Maurya founded the empire around 321 BCE by overthrowing the Nanda dynasty in Magadha. Through military campaigns and diplomatic treaties, he extended control westward into Afghanistan below the Hindu Kush and southward into the northern Deccan. His consolidation relied on coinage, road-building, and administrative infrastructure, though penetration beyond core urban centers remained limited by prevailing technology.
Phase II: Zenith
Under Ashoka (c. 268–232 BCE), the empire reached its greatest extent, controlling major urban centers and trade arteries across the subcontinent except the deep south. The period produced significant achievements in art, architecture, and stone inscriptions. Trade flourished along road networks and rivers, supported by Buddhist and Jainist commercial ethics, coinage, and writing that facilitated complex economic transactions.
Phase III: Decline
After Ashoka's death the empire weakened through succession struggles and regional fragmentation. The peripheral territories, held together primarily by military commanders' loyalty rather than deep administrative integration, gradually broke away. The last Mauryan ruler, Brihadratha, was assassinated by his general Pushyamitra Shunga around 185 BCE, who founded the Shunga dynasty and ended Mauryan rule over Magadha.
