Bayan of the Baarin (Mongolian: Баян; 1236 – January 11, 1295), or Boyan (Chinese: 伯顔; pinyin: Bóyán), was an ethnic Mongol general of the Yuan dynasty of China. He was known to Marco Polo as "Bayan Hundred Eyes" (probably from a confusion with Chinese: 百眼; pinyin: Bǎiyǎn).[1] He commanded the army of Kublai Khan against the Southern Song dynasty, ushering in the Southern Song collapse and the conquest of southern China by the Yuan dynasty.
"Bayan" literally means "rich" in the Mongolian language.
