Origins and Spread of the Stupa Form

The stupa's dome shape descends from pre-Buddhist South Asian burial mounds, earthen tumuli raised over the remains of the dead, a form the earliest Buddhist community adapted to house relics of the Buddha after his death and cremation, distributed according to tradition among several communities that each built a stupa over its share.

The Mauryan emperor Ashoka, who converted to Buddhism in the third century BCE and became its most consequential royal patron, is credited with a vast stupa building program across the Indian subcontinent, opening earlier relic stupas and redistributing their contents into many new ones as part of his effort to spread the faith. From this South Asian base the stupa traveled with Buddhism itself along trade and pilgrimage routes: south to Sri Lanka, where it developed into the large hemispherical dagoba; east along the Silk Road into Central Asia and China, where the dome flattened and multiplied into the tiered pagoda; and into Southeast Asia, where it appears both as a freestanding monument, as at the vast stepped stupa of Borobudur in Java, and as the crowning chedi of a temple compound. Despite this wide geographic range and considerable variation in scale and elaboration, the underlying logic never changed: a stupa marks or contains something sacred and is approached by moving around it rather than into it.
