Siddhārtha Gautama (Sanskrit; Pali: Siddhattha Gotama) was a spiritual teacher in the northern region of the Indian subcontinent who founded Buddhism. He is generally seen by Buddhists as the Supreme Buddha (Sammāsambuddha) of our age. The time of his birth and death are uncertain: most early 20th-century historians date his lifetime from c. 563 BCE to 483 BCE; more recently, however, at a specialist symposium on this question, the majority of those scholars who presented definite opinions gave dates within 20 years either side of 400 BCE for the Buddha's death, with others supporting earlier or later dates.

Gautama, also known as Śākyamuni or Shakyamuni ("sage of the Shakyas"), is the key figure in Buddhism, and accounts of his life, discourses, and monastic rules are believed by Buddhists to have been summarized after his death and memorized by his followers. Various collections of teachings attributed to Gautama were passed down by oral tradition, and first committed to writing about 400 years later. Early Western scholarship tended to accept the biography of the Buddha presented in the Buddhist scriptures as largely historical, but currently "scholars are increasingly reluctant to make unqualified claims about the historical facts of the Buddha's life and teachings."

Life

The primary sources of information regarding Siddhārtha Gautama's life are the Buddhist texts. The Buddha and his monks spent four months each year discussing and rehearsing his teachings, and after his death his monks set about preserving them. A council was held shortly after his death, and another was held a century later. At these councils the monks attempted to establish and authenticate the extant accounts of the life and teachings of the Buddha following systematic rules. They divided the teachings into distinct but overlapping bodies of material, and assigned specific monks to preserve each one. From then on, the teachings were transmitted orally. From internal evidence it seems clear that the oldest texts crystallized into their current form by the time of the second council or shortly after it. The scriptures were not written down until three or four hundred years after the Buddha's death. By this point, the monks had added or altered some material themselves, in particular magnifying the figure of the Buddha.

The ancient Indians were generally not concerned with chronologies, being far more focused on philosophy. The Buddhist texts reflect this tendency, providing a clearer picture of what Shakyamuni may have taught than of the dates of the events in his life. These texts contain descriptions of the culture and daily life of ancient India which can be corroborated from the Jain scriptures, and make the Buddha's time the earliest period in Indian history for which substantial accounts exist. According to Michael Carrithers, there are good reasons to doubt the traditional account, though the outline of "birth, maturity, renunciation, search, awakening and liberation, teaching, death" must be true.
