Xiang Yu, born Xiang Ji, was the Ba Wang or Hegemon-King of Western Chu during the Chu–Han Contention period of China. A noble of the Chu state, Xiang Yu rebelled against the Qin dynasty and became a prominent warlord. He was granted the title of "Duke of Lu" by King Huai II of the restoring Chu state in 208 BC. The following year, he led the Chu forces to victory at the Battle of Julu against the Qin armies led by Zhang Han. After the fall of Qin, Xiang Yu was enthroned as the "Hegemon-King of Western Chu" and ruled a vast area covering modern-day central and eastern China, with Pengcheng as his capital. He engaged Liu Bang, the founding emperor of the Han dynasty, in a long struggle for power, known as the Chu–Han Contention, which concluded with his eventual defeat at the Battle of Gaixia and his suicide.
