During the Gojoseon–Yan War, which occurred in the late 4th century BC, the Yan feudal state invaded the Gojoseon kingdom.[1] The Yan military campaign was led by General Qin Kai.[1] The invasion resulted in Yan's conquest of the Liaodong Peninsula from Gojoseon.[1]
Around 323 BC, Yan attempted to invade Gojoseon to strengthen the authority of its king and to obtain human and material resources.[2] However, Gojoseon was able to frustrate these plans through military and diplomatic actions.[2] Yan was weakened by civil war since 316 BC, which had affected the balance of power between Gojoseon and Yan.[2] Gojoseon applied political and military pressure on Yan during the period.[2] This escalated the tension between the two states, which would ultimately lead into the outbreak of the war.[2]
