The Mahāsāṃghika was a major division (nikāya) of the early Buddhist schools in India. They were one of the two original communities that emerged from the first schism of the original pre-sectarian Buddhist tradition. This schism is traditionally held to have occurred after the Second Buddhist council, which occurred at some point during or after the reign of Kalashoka. The Mahāsāṃghika nikāya developed into numerous sects which spread throughout ancient India.
