First Schism of Buddhism
IndiaAfter an initial period of unity, divisions in the sangha or monastic community led to the first schism of the sangha into two groups: the Sthavira (Elders) and Mahasamghika (Great Sangha). Most scholars agree that the schism was caused by disagreements over points of vinaya (monastic discipline). Over time, these two monastic fraternities would further divide into various Early Buddhist Schools.
