The savior of Theravada Buddhism: Bagan king Anarwatha

King Anawratha (Modern representation)

Theravada Buddhism nearly died in the 11th century and one king saved it.

By the year 1070, the oldest surviving Buddhist tradition was on life support.

 The Collapse: After decades of Chola invasions from South India, Sri Lanka—the beating heart of Theravada Buddhism—lay in ruins. The sacred city of Anuradhapura had fallen. Monasteries were abandoned. Worst of all, the ordination lineages were broken—the living transmission from the Buddha himself had been severed. Theravada was about to become a footnote in history books.

 The Unlikely Savior: Enter King Anawrahta (Aniruddha) of Bagan, in what is now Myanmar. While Sri Lanka burned, Anawrahta had spent decades building something extraordinary. He annexed the Mon kingdom of Thaton in 1057, imported entire libraries of Pali scriptures, and converted/unified his kingdom from esoteric Ari practices to orthodox Theravada under the monk Shin Arahan. He built the Shwezigon Pagoda and made Bagan a fortress of the faith.

Then, in 1071, King Vijayabahu of Sri Lanka sent an urgent request: Send monks. Our sangha is extinct.

Anawrahta didn't hesitate. He dispatched ordained monks and sacred relics across the Bay of Bengal. Those Burmese monks re-established the upasampada ordination in Sri Lanka, effectively resuscitating Theravada from the dead. It was a cross-cultural rescue mission that reversed the usual flow of Buddhism—from south to north, not north to south.

 The Forgotten Threat: Here's what makes this story even more dramatic. While all this was happening, the Khmer Empire—mighty, expansionist, and deeply committed to Hinduism —was pushing its influence across mainland Southeast Asia. Anawrahta spent his reign checking Khmer incursions and fortifying his eastern frontier, the annexion of the Mon was a way to block the Khmer progression to avoid the access to the terraserim . If Bagan had fallen, or if Anawrahta had embraced Khmer-style Hindu-Mahayana culture instead, Theravada would have had no safe harbor left in the region.

Imagine an alternate history: no Thai forest tradition, no Burmese vipassana movement, no Pali Canon preserved in Southeast Asia. The mindfulness practices millions rely on today would simply not exist.

 The Irony: The monks Anawrahta sent to save Sri Lanka would later help seed Theravada across Thailand, Laos, and Cambodia—the very regions where Khmer influence once dominated. What nearly died in the 11th century became the dominant spiritual path of half a billion people.

Next time you sit in meditation, remember: you're part of a tradition that was once a single kingdom away from extinction. History is fragile. Faith survives through solidarity, not isolation.
