Buddhism is an ancient Indian religion, which arose in and around the ancient Kingdom of Magadha (now Bihar, India). It is based on the teachings of Gautama Buddha, who lived in the 6th or 5th century BCE and was deemed a "Buddha" or an "Awakened One". Buddhist records in the Theravada tradition list Gautama Buddha as the fourth Buddha of our kalpa, while the next buddha will be Maitreya Buddha. Buddhism spread outside of Northern India beginning in the Buddha's lifetime.
In the 3rd century BCE and during the reign of the Mauryan Emperor Ashoka, the Buddhist community split into two schools: the Mahāsāṃghika and the Sthaviravāda, each of which spread throughout India and grew into numerous sub-schools. In modern times, three major branches of Buddhism exist: the Theravada in Sri Lanka and Southeast Asia, and the Mahayana in the Himalayas and East Asia, and the Vajrayana throughout Asia and specifically in Tibet, Nepal, and Bhutan.
