Gautama Buddha, also known as Siddhārtha Gautama, Shakyamuni, or simply the Buddha, was a sage on whose teachings Buddhism was founded. He is believed to have lived and taught mostly in eastern India sometime between the sixth and fourth centuries BCE.

The word Buddha means “awakened one” or “the enlightened one”. “Buddha” is also used as a title for the first awakened being in a Yuga era. In most Buddhist traditions, Siddhartha Gautama is regarded as the Supreme Buddha (Pali sammāsambuddha, Sanskrit samyaksaṃbuddha) of our age. Gautama taught a Middle Way between sensual indulgence and the severe asceticism found in the śramaṇa movement common in his region. He later taught throughout regions of eastern India such as Magadha and Kosala.
