Mulan Khan (d.1466); was the Mongol Khan of the Northern Yuan Dynasty in Mongolia and he was the eldest son of Tayisung Khan; Emperor Taizong of Northern Yuan. Mulan Khan succeeded his younger brother Markorgis Khan in 1465; but due to lack of real power; he was killed by warring Mongol nobles who fought each other for dominance. After his death; the position of great khan remained vacant for nearly a decade as warring Mongol clans fought each other for power; and it was not until finally in 1475; that Manduul Khan (Manduyul) was finally crowned as the next khan.
