The page you are looking for most likely concerns King Devanampiyatissa, the third-century BCE monarch whose reign reshaped Sri Lanka's religious, cultural, and political identity. The name "Dwaniatisa" appears to be a phonetic variant of Devānampiya Tissa — a Pali honorific meaning "Beloved of the Gods" — and the two names refer to the same historical figure.
Who was King Devanampiyatissa?
Devanampiyatissa ruled the ancient kingdom of Anuradhapura from around 247 BCE to 207 BCE. He was the son of King Mutasiva and is widely regarded as one of the most consequential rulers in Sri Lankan history — not primarily for military conquest, but for the civilisational transformation that took place during his reign.
Contemporary and near-contemporary accounts of his life appear in the Mahavamsa, the Pali chronicle composed by the monk Mahanama around the 5th or 6th century CE. The chronicle treats Devanampiyatissa's reign as the beginning of a new era for the Sinhalese people.
How did Buddhism arrive in Sri Lanka under Devanampiyatissa?
The defining event of the reign was the arrival of the Buddhist missionary Arahat Mahinda on Mihintale Hill, near Anuradhapura, in approximately 247 BCE. Mahinda was the son — or, in some accounts, the spiritual emissary — of the Mauryan Emperor Ashoka of India, who had made the propagation of the Dhamma a cornerstone of his imperial policy.
According to the Mahavamsa, Devanampiyatissa encountered Mahinda while hunting on Mihintale. After a brief doctrinal exchange that demonstrated the king's readiness to receive the teaching, Mahinda delivered a sermon on the Cullahatthipadopama Sutta. The king was converted, and with him the royal court and, eventually, much of the island's population.
Arahat Mahinda's sister, the nun Sanghamitta, subsequently brought a sapling of the sacred Bodhi Tree from Bodh Gaya to Anuradhapura. That tree — the Jaya Sri Maha Bodhi — survives to this day and is venerated as the oldest historically documented tree in the world.
What monuments did Devanampiyatissa build?
The king directed the construction of several structures that defined Anuradhapura's sacred landscape for centuries:
- Thuparamaya Dagoba — traditionally regarded as the first stupa built in Sri Lanka, said to enshrine the right collarbone relic of the Buddha.
- Mahavihara Monastery — the great monastic complex that became the headquarters of Theravada Buddhism on the island and shaped the tradition's development across Southeast Asia.
- Isurumuniya Rock Temple — a rock-cut monastery adjoining a royal pleasure garden, still an active site of worship today.
- Mihintale Monastery — established at the site of Mahinda's arrival, now a major pilgrimage destination. The stupas built there remain among the most visited sacred monuments in the country.
The king also designated a protected zone around Anuradhapura — sometimes described as an early precursor to the concept of a wildlife sanctuary — reflecting the Buddhist principle of non-harm toward living beings.
What was the relationship between Devanampiyatissa and Emperor Ashoka?
The Mahavamsa records a warm diplomatic relationship between the two rulers predating the arrival of Mahinda. Devanampiyatissa and Ashoka exchanged gifts and envoys, and both were coronated in roughly the same period. Ashoka sent Devanampiyatissa royal regalia, including a crown and other insignia, as a gesture of fraternal recognition between Buddhist kingdoms.
This connection gave Sri Lanka a direct link to the Mauryan imperial network and positioned Anuradhapura as a significant node in the early Buddhist world — a status the city retained for more than a millennium.
Where did Devanampiyatissa rule, and what remains today?
Devanampiyatissa ruled from Anuradhapura, the first of Sri Lanka's great ancient capitals, located in the North Central Province. The city flourished as a capital for roughly 1,400 years before political power shifted — eventually settling in Polonnaruwa in the 10th century CE.
Anuradhapura today is a UNESCO World Heritage Site. Visitors can walk among the ruins of the Mahavihara, see the living Bodhi Tree, explore Thuparamaya and the other great dagobas, and climb to Mihintale Hill to stand at the very spot where the island's Buddhist history is said to have begun. The site is well-connected by road and rail from Colombo.
Why does Devanampiyatissa matter to Sri Lankan culture today?
Sri Lanka is a majority Theravada Buddhist nation, and that religious identity traces directly to the events of Devanampiyatissa's reign. The Esala Perahera Festival held annually in Kandy — one of the largest religious processions in Asia — is a living expression of the Buddhist culture he helped establish. The Pali canon preserved and transmitted through the Mahavihara tradition he founded remains the scriptural foundation for Theravada Buddhism worldwide.
His reign also marks the beginning of a tradition of Buddhist kingship in Sri Lanka, in which rulers understood the protection of the Sangha (monastic community) as a core royal duty — a principle that influenced statecraft on the island for over two thousand years.
How is the name "Devanampiyatissa" sometimes spelled or misread?
The name appears in several transliterated forms across colonial-era texts, travel accounts, and online sources: Devanampiya Tissa, Devanampiyatissa, Devānampiyatissa, and occasionally phonetic approximations such as Dwaniatisa, Dvaniatissa, or Dewanampatiya Tissa. All refer to the same ruler. If you encountered the name "King Dwaniatisa" in a travel itinerary or guidebook, it is almost certainly a rendering of this same king's title.
Is there a dedicated site I can visit to learn more about this king?
Mihintale, roughly 12 kilometres east of Anuradhapura, is the most historically resonant place to begin. A series of stone steps — traditionally counted at around 1,840 — leads to the summit shrine and the Aradhana Gala (Meditation Rock) where Mahinda preached to the king. The site also holds the Kantaka Cetiya stupa, a hospital ruin, and a refectory, giving a good sense of monastic life as it existed from the 3rd century BCE onward.
Anuradhapura's Archaeological Museum holds artefacts, inscriptions, and scale models that contextualise the monuments. A half-day visit to Mihintale combined with a full-day tour of Anuradhapura's sacred city gives a thorough introduction to the world Devanampiyatissa created.
