Around the fifth century BCE in the Ganges plain of northern India, Siddhartha Gautama, the Buddha, taught the Four Noble Truths and the Eightfold Path as a discipline for ending suffering through ethical conduct, meditation and insight. The teaching spread through monastic communities (the sangha) and lay patronage, dividing into Theravada, Mahayana and later Vajrayana traditions. Carried along trade routes, it reached Sri Lanka, Central Asia, China, Korea, Japan and Southeast Asia. It became one of the world's major religious and philosophical systems.
Buddhism reshaped the ethics, monastic institutions, art and learning of much of Asia for more than two millennia, and its monasteries and stupa-and-temple complexes anchored towns and pilgrimage centres across the continent.
