Inthawichayanon (Thai: อินทวิชยานนท์,,, in Thai pronounced as /in.tʰa.wí.tɕʰa.jaː.non/; Burmese: အရှင်ဣန္ဒဝိဇယာနန္ဒဘုရင်မင်းမြတ်, [[File:LN-King Inthawichayanon.png|125px]], c. 1817 – 23 November 1897) was the 7th Ruler of Chiang Mai and King of Lanna from 1870 until his death in 1897. His daughter, Princess Dara Rasmi of Chiang Mai became King Rama V's Princess Consort. During his reign, the ties of the previously independent tributary state with the central government in Bangkok were intensified, culminating in the creation of the Monthon Phayap in 1892, by which Lanna was formally annexed.[1]
Born on c. 1817 as Prince Inthanon (เจ้าอินทนนท์) to Phraya Maha Phrom Khamkhong (พระยามหาพรหมคำคง), lord viceroy of Chiangmai, and Princess Khamla (คำหล้า). He is a grandson of Prince Khamfan, the 3rd ruler of Chiangmai. He was concerned about the preservation of the mountain forests in the Thai highlands. Before he died, he ordered that his remains be kept at Doi Luang, the highest mountain of the Thanon Thong Chai Range, which was renamed Doi Inthanon after his death.[2]
In 1883, a rumour that Queen Victoria of Great Britain intended to adopt his daughter, Dara Rasmi, spread from Burma to Chiangmai and Bangkok, alarmed Siamese government of British desire in Lanna. The Siamese King sent his brother, Prince Bijitprijakara, to Chiangmai to forward the Grand Prince's proposal to Dara Rasmi.
He was only sovereign prince in history who awarded Knight of the Order of the Royal House of Chakri.
