Nonsense. She died in childbirth from a broken heart

Queen Genepil (1905-1938) the last queen of Mongolia.

She was executed in May, 1938, shot as part of the systematic purge/destruction of Mongolian culture, in which a vast amount of the population were killed, including almost all the shamans and Buddhist lamas.

Star Wars (the movie) took inspiration of course.
