The ancient Chinese chariot () was used as an attack and pursuit vehicle on the open fields and plains of ancient China from around 1200 BCE. Chariots also allowed military commanders a mobile platform from which to control troops while providing archers and soldiers armed with dagger-axes increased mobility. They reached a peak of importance during the Spring and Autumn period, but were largely superseded by cavalry during the Han Dynasty. History Traditional sources attribute the invention of the chariot to the Xia dynasty minister Xi Zhong,<ref>{{cite book |title=Shiben |chapter-url=https://zh.wikisource.org/wiki/%E4%B8%96%E6%9C%AC#%E5%A4%8F_3 |chapter=Chapter on Inventions (作篇) - Xia (夏) |quote="奚仲作車。"}}</ref> and say they were used at the Battle of Gan (甘之戰) in the 21st century BCE. However archeological evidence shows that small scale use of the chariot began around 1200 BCE in the late Shang dynasty. Contemporary oracle bone inscriptions of the character depict a chariot-like two wheeled vehicle with a single pole for the attachment of horses. Chariots reached their apogee and remained a powerful weapon until the end of the Warring States Period (471–221 BCE) when increasing use of the crossbow, massed infantry, the adoption of standard cavalry units and the adaptation of nomadic cavalry (mounted archery) took over. Chariots continued to serve as command posts for officers during the Qin and Han Dynasties while armored chariots were also used by the Han Dynasty against the Xiongnu Confederation in the Han–Xiongnu War, specifically at the Battle of Mobei in 119 CE. General Wei Qing's army, setting off from Dingxiang, encountered the Xiongnu Chanyu's army of 80,000 cavalry. Wei Qing ordered his troops to arrange heavy-armored chariots in a ring formation, creating mobile fortresses. With changes in the nature of warfare, as well as the increasing availability of larger breeds of horses, during the Qin and Han Dynasties (221 BCE – 220 CE) the chariot was replaced by cavalry and infantry, and the single-pole chariot became less important. At this time the double shaft chariot developed as a transport vehicle which was light and easy to handle. During the Eastern Han (25–220 CE) and later during the Three Kingdoms Period (220–280 CE), the double shaft chariot was the predominant form. This change is seen in innumerable Han Dynasty stone carvings and in many ceramic tomb models. Over time, as society evolved, the early chariot of the Pre-Qin period gradually disappeared.
