Demchugdongrub

Demchugdongrub, also known as Prince De, courtesy name Xixian (希賢), was a Qing dynasty Mongol prince descended from the Borjigin imperial clan who lived during the 20th century and became the leader of an independence movement in Inner Mongolia. He was most notable for being the chairman of the pro-Japanese Mongol Military Government (1938–39) and later of the puppet state of Mengjiang (1939–45), during the Second Sino-Japanese War. In modern day, some see Demchugdongrub as a Mongol nationalist promoting Pan-Mongolism while others view him as a traitor and as the pawn of the Japanese during World War II.
