What happened
Roughly two decades after the First Council, disagreement over ten specific points of monastic discipline produced Buddhism's first major split. According to the standard account, the Sthaviravada school insisted on strict observance of the disputed rules, which the majority of the assembled monks rejected. The result was a division: either the Sthaviravada left the wider community, or the majority distanced themselves from the Sthaviravada and began calling themselves Mahasanghika, "the great assembly." World History Encyclopedia is direct that every later Buddhist school traces back to this rupture: "All the later schools then developed from this first schism."
Why it matters
The Second Council's split is the root from which Theravada, Mahayana, and eventually Vajrayana Buddhism all descend, and it established a recurring pattern in Buddhist history: disagreements over monastic discipline and doctrine producing new, self-identified schools rather than being resolved by central authority, since Buddhism has never had an equivalent of a single pope or council with binding power over all its adherents.
How we know
The Second Council is recorded in later Buddhist chronicles from multiple textual traditions, and modern scholars note the surviving accounts do not fully agree on the details, which is why historians describe the episode's specifics, though not the fact of the schism itself, as debated.
