Qin dynasty
Note: King Zhaoxiang of Qin (秦昭襄王) had already been ruling Qin for 51 years when Qin annihilated the Zhou dynasty; however the other six warring states were still independent regimes. Some Chinese historiographers thus used the next year (the 52nd year of King Zhaoxiang of Qin) as the official succession from the Zhou dynasty.

Liaodong came under the rule of the Gojoseon kingdom which emerged in the region. In the late 4th century BC, the Chinese State of Yan invaded and conquered this region from Gojoseon.
