See it on the World Religions map →What it is
Tradition says Siddhartha was born a prince of the Shakya clan at Lumbini, in today's Nepal. At 29, shaken by seeing old age, sickness and death, he left home and spent six years in extreme fasting before choosing a 'middle way'. Meditating under a tree at Bodh Gaya, he reached enlightenment, then taught for some 45 years across the Ganges plain, founding an order of monks and nuns. He died at about 80 at Kushinagar.
Why it matters
His teaching on suffering and its end now guides about 320 million Buddhists, and it spread from India across Asia, reaching Korea in AD 372.
Life, legacy and sources
The Pali Canon and other scriptures, written down centuries later; Ashoka's pillar at Lumbini (about 249 BC) marks it as his birthplace. Most scholars accept that he was a real person.
Questions and debates
His dates: traditionally 563–483 BC, but most scholars now place his death around 400 BC. Many details of his life story are legend.

Connections (6)
▸Siddhartha Gautama, the Buddha founded BuddhismMostly agreed by scholars
The connection
After his enlightenment, the Buddha gathered disciples, starting with five former companions at Sarnath, and created the sangha, an order of monks and later nuns with rules for shared life. His teaching, memorized and chanted by followers, became the Dharma that Buddhism preserves. After his death, tradition says, councils met to agree on it.
When and where
Northeast India, about 445–400 BC by scholarly dating; tradition says the First Council met at Rajagriha soon after his death.
How do we know?
Early texts in several languages, and Ashoka's inscriptions within about two centuries, confirm an established community claiming his teaching. The details come from tradition.
Questions and debates
How much of the scripture records the Buddha's own words, and whether the First Council happened as described, remain open questions.
▸Siddhartha Gautama, the Buddha attained enlightenment at Bodh Gaya, site of the Buddha's enlightenmentFaith & scripture
The connection
Buddhist tradition teaches that Siddhartha, after six years of austerity, sat beneath a fig tree by the Niranjana River and resolved not to rise until he understood suffering. Through the night he resisted the tempter Mara, recalled past lives, and at dawn became the Buddha. The tree became the Bodhi, or 'awakening', tree.
When and where
Uruvela, now Bodh Gaya in Bihar, India; traditionally 528 BC, about 445 BC by scholarly dating, when he was 35 according to tradition.
How do we know?
The enlightenment itself is a matter of faith. That this spot was revered as its site is documented by Ashoka's shrine and early pilgrims' accounts.
Questions and debates
Early texts give differing accounts of what the Buddha realized that night, and Buddhist schools understand enlightenment in different ways.
▸Siddhartha Gautama, the Buddha taught Four Noble TruthsMostly agreed by scholars
The connection
In his first sermon, 'Setting in Motion the Wheel of the Dharma', the Buddha told his five former companions that there is a middle way between indulgence and self-torment, and laid it out as four truths about suffering. One of them, Kondanna, understood at once and became the first disciple.
When and where
The Deer Park at Sarnath, near Varanasi, some weeks after the enlightenment; about 445 BC by scholarly dating.
How do we know?
The sermon appears in the Pali Canon and in parallel Sanskrit, Chinese and Tibetan versions, suggesting it goes back to the earliest community.
Questions and debates
Whether the first sermon really used this exact four-part form, or later tradition framed his teaching that way, is unresolved.
▸Siddhartha Gautama, the Buddha challenged the Brahmin priests of Vedic religionMostly agreed by scholars
The connection
The Buddha rejected the authority of the Vedas and the value of animal sacrifice, and taught that spiritual worth comes from conduct, not birth into the Brahmin class. He reused Vedic-era terms like karma and dharma but gave them ethical meanings, part of a wider challenge from wandering ascetics called shramanas.
When and where
The Ganges plain of northeast India, in kingdoms like Magadha and Kosala, about the 5th century BC; Mahavira, founder of Jainism, mounted a parallel challenge.
How do we know?
Early Buddhist texts, such as the Pali Canon, record debates with Brahmins, including discourses on who is a 'true Brahmin'.
Questions and debates
How far the Buddha reacted against Vedic religion versus drew on it, and how dominant Brahmin priests were in his region then, is debated.
▸Siddhartha Gautama, the Buddha first preached near Varanasi (Kashi), holiest Hindu cityMostly agreed by scholars
The connection
After his enlightenment, the Buddha walked about 250 kilometers west from Bodh Gaya to the Deer Park at Sarnath, about 10 kilometers from Varanasi, already a famous holy city. There he gave his first sermon. Sarnath became one of Buddhism's four great pilgrimage sites, a Buddhist landmark beside Hinduism's holiest city.
When and where
Sarnath (ancient Isipatana), near Varanasi in Uttar Pradesh, about 445 BC by scholarly dating; Ashoka later raised a pillar there.
How do we know?
Ashoka's pillar and lion capital, the Dhamek Stupa and monastery ruins excavated since the 1830s confirm Sarnath's early sacred status.
Questions and debates
Tradition says he chose Sarnath because his former companions were there; what religious role the site had before Buddhism is unclear.
▸Mahavira was a contemporary of Siddhartha Gautama, the BuddhaMostly agreed by scholars
The connection
Mahavira and the Buddha taught in the same region, Magadha and neighboring kingdoms, at roughly the same time, and both came from the shramana movement of wandering renouncers who rejected Vedic sacrifice. Both taught karma, rebirth and liberation, but the Buddha rejected Mahavira's extreme austerity as one-sided.
When and where
Bihar, northeast India, about 500–400 BC; both traditions say King Bimbisara of Magadha and his court supported their teacher.
How do we know?
The Pali Canon names Mahavira as Nigantha Nataputta and describes debates with his followers; Jain sources describe the same kings and towns.
Questions and debates
They probably never met. Their exact dates are uncertain, and which died first is disputed; Buddhist texts say Mahavira did.
