The history of Buddhism can be traced back to the 5th century BCE. Buddhism arose in Ancient India, in and around the ancient Kingdom of Magadha, and is based on the teachings of the ascetic Siddhārtha Gautama. The religion evolved as it spread from the northeastern region of the Indian subcontinent throughout Central, East, and Southeast Asia. At one time or another, it influenced most of Asia. The history of Buddhism is also characterized by the development of numerous movements, schisms, and philosophical schools, among them the Theravāda, Mahāyāna and Vajrayāna traditions, with contrasting periods of expansion and retreat. Shakyamuni Buddha (5th cent. BCE) Siddhārtha Gautama (5th cent. BCE) was the historical founder of Buddhism. The early sources state he was born in the small Shakya (Pali: Sakya) Republic, which was part of the Kosala realm of ancient India, now in modern-day Nepal. He is thus also known as the Shakyamuni (literally: "The sage of the Shakya clan"). The Early Buddhist Texts contain no continuous life of the Buddha, only later after 200 BCE were various "biographies" with much mythological embellishment written. All texts agree however that Gautama renounced the householder life and lived as a sramana ascetic for some time studying under various teachers, before attaining nirvana (extinguishment) and bodhi (awakening) through meditation. For the remaining 45 years of his life, he traveled the Gangetic Plain of north-central India (the region of the Ganges/Ganga river and its tributaries), teaching his doctrine to a diverse range of people from different castes and initiating monks into his order. The Buddha sent his disciples to spread the teaching across India. He also initiated an order of nuns. He urged his disciples to teach in the local language or dialects. He spent a lot of his time near the cities of Sāvatthī, Rājagaha and Vesālī (Skt. Śrāvastī, Rājagrha, Vāiśalī). By the time of his death at 80, he had thousands of followers. Early Buddhism After the death of the Buddha, the Buddhist sangha (monastic community) remained centered on the Ganges valley, spreading gradually from its ancient heartland. The canonical sources record various councils, where the monastic Sangha recited and organized the orally transmitted collections of the Buddha's teachings and settled certain disciplinary problems within the community. Modern scholarship has questioned the accuracy and historicity of these traditional accounts. The first Buddhist council is traditionally said to have been held just after Buddha's Parinirvana,
