Deng () was a Chinese vassal state during the Shang and Eastern Zhou dynasties ruled by the Man (æÂ¼) family.
Sources conflict as to whether the State of Deng was situated in Dengzhou (é§å·Â/éÂÂå·Â), Henan Province or Xiangfan (è¥Âæ¨Â), Hubei Province.
Shang dynasty King Wu Ding (æÂ¦ä¸Â) (reigned 1250âÂÂ1192 BCE) conferred the lands of the State of Deng on his younger brother ZàMàn (Ã¥ÂÂæÂ¼) who passed it down to later generations. During the reign of Wú Là(å¾离) Deng became rich and powerful for a time but its influence declined with the rise of the hegemonies during the Spring and Autumn period.
In 688 BCE, King Wén of Chàhad to pass through the State of Deng in order to attack the State of ShÃÂn. Even though Dèng was the birthplace of Dèng Màn (éÂÂæÂ¼), one of the wives of King Wén's father King Wàof Chà(æ¥ÂæÂ¦çÂÂ), the State of Deng lay on the borders of the State of Chu such that its overthrow would prove convenient for the expansion of Chu. Three vigilant chancellors of the State of Deng, ZhuëshÃÂng (騠çÂÂ¥/éªÂçÂÂ¥), DÃÂnshÃÂng (èÂÂçÂÂ¥) and YÃÂngshÃÂng (é¤ÂçÂÂ¥/å »çÂÂ¥) urged their lord to kill King Wén. The Marquess of Deng did not listen. King Wén of Chu passed through the State of Deng and attacked the State of Shen. On his return the King attacked Deng.
In 678 BCE King Wén of Chu conquered State of Deng. With the annexation of the States of Shen and Deng, the State of Chu extended its territory into the Nanyang Basin. Afterwards its people adopted the surname Deng (é§/éÂÂ) which is still common today.
