Early Buddhism

Early Buddhism refers to the teachings of Siddhartha Gautama, the historical Buddha, who lived and taught in the Ganges plain of northern India around the 5th century BCE. These teachings — the Four Noble Truths, the Eightfold Path, dependent origination, the three marks of existence — form the common foundation of every Buddhist tradition that followed.

The Historical Buddha

Born into a warrior-caste family in what is now southern Nepal, Siddhartha Gautama left home at 29 to seek a solution to suffering. After years of ascetic practice and study with various teachers, he sat beneath a tree in Bodh Gaya and, through sustained meditative inquiry, arrived at what he called awakening (bodhi). He spent the remaining 45 years of his life teaching a path he described as the "middle way" between indulgence and self-mortification.

Core Teachings

The Buddha's teaching was radical in its context: he rejected the authority of the Vedas, denied the existence of an eternal self (Atman), and insisted that liberation was available to anyone regardless of caste or birth. His core framework — suffering (dukkha), its origin in craving (tanha), the possibility of its cessation (nirodha), and the path leading to cessation (magga) — remains the structural foundation of all Buddhist traditions.

After the Buddha's death (c. 400 BCE), his teachings were preserved orally by communities of monks and nuns. Over the following centuries, disagreements about interpretation and monastic rules led to the formation of roughly eighteen early schools. Of these, only one survives intact: the Theravada, which preserves its teachings in the Pali language. The others contributed to the emergence of Mahayana Buddhism, which reinterpreted the Buddha's teachings through new philosophical frameworks while claiming to recover his deeper intent.

Why It Matters on This Map

Early Buddhism sits at the root of the Buddhist family tree. Every Buddhist tradition — Theravada, Mahayana, Vajrayana, Zen, Dzogchen — traces its lineage back to these original teachings, even as they interpret and elaborate them in vastly different ways. Understanding this common root illuminates both what unites Buddhist traditions and where they genuinely diverge.
