Ji Chang is an important figure on the Xiqi side of Investiture of the Gods and one of the founders of the political cause that develops into the Zhou dynasty. Later honored as King Wen of Zhou, he is remembered for benevolent rule and for becoming the leading western lord during the final years of the Shang.
Under King Zhou, Ji Chang falls under suspicion and is imprisoned at Youli. After his release, he returns to Xiqi, continues strengthening his territory, and gathers capable people around him.
When Jiang Ziya is fishing by the Wei River, Ji Chang recognizes his ability and receives him with great respect. By bringing Jiang Ziya into the Zhou cause, Ji Chang helps establish the political and strategic foundation from which Xiqi grows into a serious rival to the Shang.
After Ji Chang’s death, his son Ji Fa inherits the cause and ultimately leads the campaign against the Shang. Ji Chang is not primarily a martial character, but his connections to Jiang Ziya, Ji Fa, and the entire Xiqi camp make him a central political node in the Investiture narrative.
