Schism (religion)
In Buddhism, the first schism was set up by Devadatta, during Buddha's life. After Buddha's passing away, the early Buddhist schools developed various schisms. In the old texts, 18 or 20 early schools are mentioned. Later, there were the Mahayana and Vajrayana movements, which can be regarded as being schismatic in origin. There are now perhaps thousands of different Buddhist sects.
