The Fourth Buddhist Council was held at Kundalavan in Kashmir during the 1st-2nd century CE (1st century A.D.) under the patronage of Kushan ruler Kanishka. This council led to the division of Buddhism into Hinayana (Theravada) and Mahayana schools. The first council was at Rajagriha, second at Vaishali, and third at Pataliputra - but these were all much earlier (pre-1st century BCE).
