The History of Buddhism

Era I · c. 1500–600 BCE

Before the Buddha

Ancient India before Buddhism

The Buddha emerged from a world already filled with competing religious and philosophical traditions. Vedic ritual culture existed alongside wandering ascetics, philosophers and seekers who questioned sacrifice, rebirth, suffering and the nature of existence.

Era II · c. 5th century BCE

The Life of the Buddha

Buddhist tradition remembers Siddhartha Gautama leaving the life expected of him in search of an answer to suffering. His awakening and subsequent teachings gave rise to the community that would eventually become Buddhism.

The exact dates of Siddhartha Gautama's life remain debated. Traditional Buddhist chronologies and modern scholarly reconstructions differ considerably, so this timeline treats his life as belonging to approximately the 5th century BCE. Modern reconstructions often place him somewhere around the 6th–5th centuries BCE, but the chronology is not certain.

Era III · c. 5th–3rd centuries BCE

The Early Sangha

After the Buddha's death, generations of monks and nuns preserved his teachings primarily through oral transmission. As communities spread, questions about doctrine, discipline and interpretation gradually produced different Buddhist schools.

Era IV · 3rd century BCE

The Age of Ashoka

Buddhism entered a dramatically different phase during the reign of the Mauryan emperor Ashoka. Royal patronage, inscriptions and missionary traditions helped transform Buddhism from a primarily regional movement into a religion spreading across much larger territories.

Ashoka ruled approximately 268–232 BCE.

Era V · c. 3rd century BCE–1st century CE

Buddhism Begins to Spread

Merchants, monks, pilgrims, rulers and trade networks carried Buddhism beyond its early Indian heartland. Different environments gradually reshaped Buddhist art, institutions and practice.

Era VI · c. 1st century BCE–5th century CE

New Buddhist Traditions Emerge

Buddhist thought continued evolving. New scriptures, philosophical movements and ideals expanded the ways Buddhists understood enlightenment and the path toward it.

Era VII · c. 1st–6th centuries CE

Buddhism Reaches China

As Buddhism entered China, translators and teachers faced an enormous challenge: explaining Indian Buddhist concepts within a civilization possessing its own ancient philosophical traditions. Buddhism gradually became deeply rooted in Chinese religious life.

Era VIII · 4th–9th centuries CE

Buddhism Across East Asia

Buddhism moves from China into Korea and Japan while each society develops distinctive traditions, institutions, art and relationships between Buddhism and political authority.

Era IX · c. 7th–13th centuries CE

Vajrayāna and the Himalayan World

Esoteric forms of Buddhist practice develop in India and become particularly influential throughout the Himalayan world. Their transmission into Tibet eventually creates one of Buddhism's most distinctive intellectual and ritual civilizations.

Era X · c. 5th–15th centuries CE

Buddhism in South and Southeast Asia

Theravāda Buddhism becomes deeply rooted throughout Sri Lanka and later across significant portions of mainland Southeast Asia, interacting with kingdoms, local cultures and earlier religious traditions.

Era XI · c. 8th–13th centuries CE

The Decline of Buddhism in India

Buddhism gradually loses much of its institutional presence in the land where it began. No single invasion, ruler, religion or event caused this. Over centuries, changing royal patronage, institutional and economic change, a transforming religious landscape, interaction and competition with other traditions, political instability and the disruption of major monasteries all played a part.

Era XII · c. 10th–17th centuries CE

Great Buddhist Cultures

Buddhist history no longer has a single centre. Across Asia, distinct Buddhist civilizations develop side by side, each with its own schools, institutions, art and relationship to power.

Era XIII · 18th–early 20th centuries

Buddhism Meets the Modern World

Colonialism, industrialization, modern science, Christian missionary activity, nationalism and new forms of scholarship profoundly alter Buddhist societies. Buddhists respond not merely by defending tradition, but by reforming and reinterpreting it.

Era XIV · 20th century

Buddhism Becomes Global

Migration, scholarship, war, colonial collapse and global communication bring Buddhist traditions into sustained contact with societies far beyond Asia.

Era XV · 21st century

Buddhism Today

Buddhism today exists simultaneously as ancient religious traditions, living monastic cultures, philosophical systems, meditation practices, diaspora identities and global spiritual movements.
