Second Buddhist council

The Second Buddhist council took place approximately in 334 BCE, seventy years after the Buddha's parinirvāṇa. The Second Council resulted in the first schism in the Sangha, probably caused by a group of reformists called Sthaviras who split from the conservative majority Mahāsāṃghikas. After unsuccessfully trying to modify the Vinaya, a small group of "elderly members", i.e. sthaviras, broke away from the majority Mahāsāṃghika during the Second Buddhist council, giving rise to the Sthavira sect.

Regarding this matter, L. S. Cousins writes, "The Mahāsāṃghikas were essentially a conservative party resisting a reformist attempt to tighten discipline. The likelihood is that they were initially a larger body, representing the mass of the community, the mahāsaṃga."

The Śāriputraparipṛcchā contains an account in which an old monk rearranges and augments the traditional Vinaya, consequently causing dissention among the monks that required the king's arbitration and eventually precipitating the first schism. As stated in the Śāriputraparipṛcchā:

He copied and rearranged our Vinaya, developing and augmenting what Kāśyapa had codified and which was called "Vinaya of the Great Assembly" (Mahāsāṃghavinaya). [...] The king considered that [the doctrines of the two parties represented] were both the work of the Buddha, and since their preferences were not the same, [the monks of the two camps] should not live together. As those who studied the old Vinaya were in the majority, they were called the Mahāsāṃghika; those who studied the new [Vinaya] were in the minority, but they were all Sthaviras; thus they were named Sthavira.
