Naratheinkha
Naratheinkha (, ; 1141–1174) was king of Pagan dynasty of Burma (Myanmar) from 1171 to 1174. He appointed his brother Narapati Sithu heir apparent and commander-in-chief. It was the first recorded instance in the history of the dynasty that the king had given up the command of the army. The king was assassinated by Aungzwa, one of Sithu's servants, after the king had raised one of Sithu's wives to queen.
According to G.H. Luce, there is no inscriptional evidence that Naratheinkha or any kings between 1165 and 1174 ever existed. Other historians such as Htin Aung do not agree with Luce's "conjecture".
