Siddhārtha Gautama (Sanskrit: सिद्धार्थ गौतम; Pali: Siddhattha Gotama) was a spiritual teacher who founded Buddhism.[1] In most Buddhist traditions, he is regarded as the Supreme Buddha (P. sammāsambuddha, S. samyaksaṃbuddha) of our age, "Buddha" meaning "awakened one" or "the enlightened one." [note 1] The time of his birth and death are uncertain: most early 20th-century historians dated his lifetime as c. 563 BCE to 483 BCE,[2] but more recent opinion dates his death to between 486 and 483 BCE or, according to some, between 411 and 400 BCE.[3][4] By tradition, Gautama is said to have been born in the small state of Kapilavastu, in what is now Nepal, and later to have taught primarily throughout regions of eastern India such as Magadha and Kośala.[5][6]
