Jizhou District was known as Wuzhong, Yuyang and Jizhou in ancient times. According to "Taiping Huanyu Ji": In the 18th year of Kaiyuan, the three counties of Youzhou were divided into Yuyang County, Sanhe County and Yutian County and were established in Jizhou. The ancient Jimen Pass was named after the state. In the Qin Dynasty, Wuzhong County was established and belonged to Youbeiping County. In the Tang Dynasty, Yuyang County was transferred to Wuzhong County (Yutian). In the second year of the Republic of China (1913), Jizhou was renamed Jixian and belonged to Shuntian Prefecture. In 1973, it was placed under Tianjin City. In 2016, Ji County was abolished and Jizhou District was established.
