Wang Du

Wang Du, born Liu Yunlang, was a Chinese warlord during the early Five Dynasties and Ten Kingdoms period who ruled as the military governor of Yiwu around modern Dingzhou in Hebei. He seized control of Yiwu from his adoptive father Wang Chuzhi in a coup and subsequently ruled it semi-independently as a vassal of Jin and Jin's successor state Later Tang. In 928, the Later Tang emperor Mingzong, believing that Wang was about to openly rebel, ordered a general campaign against him and, after a lengthy siege, Wang killed himself and his family by self-immolation as his capital was falling.
