Zhou people lived in the far west, blocked by mountains and rivers, and merchants called them Xiqi. The Zhou people submitted to the Shang Dynasty, and the oracle bones unearthed show that when the Zhou people sacrificed, they also paid homage to the merchant ancestors and the recently deceased Shang king.

After King Wen's death, his son King Wu of Zhou led a confederation of Western Turk tribes to the East, crossing the Yellow River and attacking the Shang capital. In February 1046 BC, the Xiqi Expeditionary Force engaged the merchants in full-scale war at the Shang suburb Makiye. King Shang burned himself to death, and Western Zhou was established.
