What happened

After Ashoka's death in 232 BCE, the Maurya Empire passed through roughly fifty years of weaker rulers who steadily lost control over the empire's outlying territories. Regional governors and local elites reasserted independence as the centralized system Chandragupta and Chanakya had built began to fragment. In 185 BCE, Brihadratha, the last Mauryan ruler, was assassinated by his own commander-in-chief, the Brahmin general Pushyamitra Shunga, during a military parade, and Pushyamitra seized the throne to found the Shunga dynasty. With the Mauryan collapse, the Khyber Pass and India's northwestern frontier were left without a strong central defender, opening the way for the Greco-Bactrian king Demetrius to push into Afghanistan and northwestern India within a matter of decades, founding the Indo-Greek kingdoms that followed.

Why it matters

The Mauryan collapse ended the subcontinent's first experiment in pan-Indian centralized rule and reopened its northwestern frontier to outside powers, setting up the sequence of Indo-Greek, Scythian, and eventually Kushan rule that would follow over the next several centuries. It also shows how quickly a highly centralized administrative state, dependent on strong rulers at the center, can unravel once that leadership weakens.

How we know

The assassination of Brihadratha and Pushyamitra's founding of the Shunga dynasty are recorded in Puranic dynastic lists and corroborated by later Buddhist sources, which, being hostile to Pushyamitra, also describe him persecuting Buddhist institutions after taking power.
