How did zhou a frontier state most affect the Shang Dynasty?

Zhou, originally a frontier state during the Shang Dynasty, significantly impacted the Shang through its military and cultural exchanges. The Zhou gradually gained power and influence, eventually leading to their rebellion against the Shang. The Zhou's ideological promotion of the "Mandate of Heaven" helped justify their overthrow of the Shang, framing it as a moral and divine right. This shift not only ended Shang rule but also laid the foundation for the Zhou Dynasty's governance and philosophy.
