Devanampriya (Devanagari: देवानंप्रिय or देवानम्प्रिय), also called Devanampiya (Brahmi script: 𑀤𑁂𑀯𑀸𑀦𑀁𑀧𑀺𑀬, Devānaṃpiya), was a Pali honorific epithet used by a few Indian monarchs, but most particularly the 3rd Mauryan Emperor Ashoka The Great (r.269-233 BCE) in his inscriptions (the Edicts of Ashoka).
It is often used by Ashoka in conjunction with the title Priyadasi, which means "He who regards others with kindness", "Humane".
[4][5] Prinsep in his study and decipherment of the Edicts of Ashoka had originally identified Devanampriya Priyadasi with the King of Ceylon Devanampiya Tissa of Anuradhapura.
However, in 1837, George Turnour discovered Sri Lankan manuscripts (Dipavamsa, or "Island Chronicle" ) associating Piyadasi with Ashoka: "Two hundred and eighteen years after the beatitude of the Buddha, was the inauguration of Piyadassi, .... who, the grandson of Chandragupta, and the son of Bindusara, and was at the time Governor of Ujjayani.
Both the lowly and the exalted must be told : "If you act thus, this matter (will be) prosperous and of long duration, and will thus progress to one and a half."
