Question

How did Buddhism grow and change after the Buddha died?

Answer 1

here is your answer

After Siddhartha Gautama passed away, the community he founded slowly evolved into a religion-like movement and the teachings of Siddhartha became the basis ofBuddhism. ... Archaeological evidence for Buddhism between the death of theBuddha and the time of Ashoka is scarce; after the time of Ashoka it is abundant.


Three months after the Buddha’s death, his disciples convened a council in order to resolve these matters and to preserve and protect the Buddha’s percepts. The first Buddhist council was thus held at Rajagaha under the patronage of King Ajatasattu at Rajagaha. This council saw the compilation of two of the three Buddhist Pitakas – Vinaya Pitaka (monastic rules) and Sutta Pitaka (sermons of the Buddha).

After Buddhism’s initial proliferation, the first schism within the Buddhist sect occurred, one hundred years after the first council. Convened at Vaisali under the patronage of King Kalasoka, the Second Buddhist council which gathered to resolve some controversies on the Vinaya ended up being divided into two groups, Sthaviravada (school of elders/traditionalists), Mahasanghika (greater sangha)
