The royal family of Mengjiang was the family of Prince Demchugdongrub, the puppet ruler of Mengjiang, a part of Inner Mongolia controlled by the Japanese during the Second Sino-Japanese War. While Mengjiang was a de-jure military dictatorship, the state was a de-facto monarchy. Prince Demchugdongrub was a descendant of the Borjigins, the clan to which Genghis Khan also belonged.
