Sukkasem na Chiengmai

Sukkasem na Chiengmai, Prince Uttarakan Koson (; 1880 – 20 March 1913), was a member of the royal family of Chiang Mai, and the first child of Kaeo Nawarat and Chamariwong.

Biography Sukkasem was the first child of Kaeo Nawarat and Chamariwong of Chiang Mai. He had two full siblings, Princess Buathip na Chiengmai and Wongtawan na Chiengmai, Prince Ratchabut. He attended St. Patrick's School in Moulmein, British Burma.

Biographer Prani Siridhara na Badalung wrote in his book that Sukkasem loved Ma Mya (Mamia), a young Mon lady of Burmese citizen in Moulmein, but this love was unrequited. Apart from the biography book, no further proof of this affair was found so far.

There have been suggestions that Prince Sukkasem and Ma Mya had to part ways because Ma Mya was under British jurisdiction, raising concerns of potential international political issues. However, scholars have researched this claim and concluded that it lacks foundation. As evidence, the marriage between Prince Inthanon of Chiang Mai and Princess Sukantha of Kengtung did not cause any political issues.

Sukkasem married Princess Buachum of Chiengmai in 1905, but they had no children. He became an alcoholic and lacked responsibility. As a result, he was appointed only as "Chao Uttarakan Kosit", a position without the right to ascend the throne, as it did not carry the status of the "Five-Tiered Umbrella Prince". Sukkasem died from chronic nerve disease on March 20, 1913, at the age of 33 (according to the modern calendar, this corresponds to 1914). His funeral took place on August 31 of the same year.
