Duke Jian of Qin (Chinese: 秦簡公; pinyin: Qín Jiǎn Gōng; 428–400 BC), personal name Ying Daozi, was from 414 to 400 BC the duke of the Qin state.[1][2]
Duke Jian was the younger son of Duke Huai and the uncle of his predecessor Duke Ling. When Duke Ling died in 415 BC, the throne was passed to Duke Jian instead of Duke Ling's son, the later Duke Xian.[1][2]
During Duke Jian's reign, the Qin state was defeated several times by the Wei state, then a major power of the Warring States period.[3]
Duke Jian reigned for 15 years and died in 400 BC, aged 28. He was succeeded by his son, Duke Hui II.[1][2]
