See it on the World Religions map →What it is
Buddhist teaching holds that life is marked by suffering, impermanence and 'non-self' (no fixed, permanent soul), and that craving keeps beings cycling through rebirth. Following the Eightfold Path leads to nirvana, the end of that cycle. Buddhists 'take refuge' in the Three Jewels: the Buddha, the Dharma (teaching) and the Sangha (community). There are three main branches: Theravada in Sri Lanka and Southeast Asia, Mahayana in East Asia, and Vajrayana in Tibet and Mongolia.
Why it matters
About 320 million followers, roughly 4% of humanity. Spreading from India, it shaped art, writing, architecture and monastic life from Sri Lanka to Korea and Japan.
Sources and history
Scriptures in Pali, Sanskrit, Chinese and Tibetan; Ashoka's inscriptions; ancient stupas and monasteries; and the travel accounts of Chinese pilgrims such as Faxian and Xuanzang.
Questions and debates
What the earliest teaching looked like before it was written down, and why Buddhism almost disappeared from India by about 1300.

Connections (5)
▸The Axial Age includes BuddhismDebated by scholars
The connection
Karl Jaspers counted the Buddha among the Axial thinkers who, between about 800 and 200 BC, turned religion inward toward ethics and personal transformation. Buddhism fits the pattern: it set aside Vedic sacrifice, offered liberation regardless of birth, and arose amid new cities and trade in the Ganges valley, alongside Jains and other renouncers.
When and where
The Ganges plain of northeast India, about 500–400 BC. Jaspers proposed the Axial Age in his 1949 book The Origin and Goal of History.
How do we know?
Buddhism's timing and themes fit, but the 'Axial Age' is a modern interpretive category, not an event, so the link is a scholarly framework.
Questions and debates
Critics say the Axial Age lumps together unrelated developments; others tie it to new wealth and cities. Later dating of the Buddha also stretches its window.
▸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.
▸Mahayana Buddhism grew out of BuddhismMostly agreed by scholars
The connection
Mahayana did not break away as a separate church. It grew inside existing Buddhist monasteries as monks and laypeople embraced new sutras teaching the bodhisattva path. Its followers came to call earlier schools 'Hinayana' (lesser vehicle), a term now avoided as derogatory. Mahayana monks often kept the same monastic code as their neighbors.
When and where
Northwest and south India, about 100 BC–AD 100; Chinese pilgrims around AD 400–700 still found Mahayana and other monks sharing monasteries.
How do we know?
Early Mahayana sutras in Gandhari and in Chinese translations from the AD 170s; inscriptions; and Faxian's and Xuanzang's descriptions of mixed monasteries.
Questions and debates
Where and among whom Mahayana began is unsettled, as is why it took centuries to appear clearly in Indian inscriptions.
▸Adi Shankara and Advaita Vedanta argued against and, legend says, helped eclipse BuddhismDebated by scholars
The connection
Shankara criticized Buddhist philosophy, especially its denial of a lasting self, in his commentaries. Later legends say he defeated Buddhist monks in debates across India and revived Vedic religion. Buddhism did fade in India, but it lasted centuries after him, under Pala kings, until monasteries like Nalanda were sacked around 1200.
When and where
India, 8th century in his writings; the debate legends come from Shankara biographies (Digvijayas) written from about the 1300s onward.
How do we know?
His critiques of Buddhist schools are in his Brahma Sutra commentary. His role in Buddhism's decline rests mainly on these late legends, not contemporary evidence.
Questions and debates
Most historians credit Buddhism's decline to lost royal patronage, absorption into Hindu devotion and Turkic raids. Ironically, critics accused Shankara of being a 'hidden Buddhist'.
▸Ambedkar leads Dalits to Buddhism revived Indian BuddhismHistorical record
The connection
Buddhism had largely vanished from India by about the 1200s, outside the Himalayas. Ambedkar's mass conversion launched Navayana, 'new vehicle', Buddhism, which reads the Buddha's teaching as a path of social liberation. His 'The Buddha and His Dhamma' (1957) is its key text. India's census counts about 8.4 million Buddhists, most Ambedkarite.
When and where
Deekshabhoomi, Nagpur, October 14, 1956; Burmese monk U Chandramani gave the vows; Ambedkar died December 6, 1956.
Historical evidence
India's census shows Buddhists jumping from about 181,000 in 1951 to 3.25 million in 1961 and 8.4 million in 2011.
Questions and debates
Some Buddhists question Navayana's departures from traditional doctrine on karma and rebirth, and census counts may undercount converts.
