King Wu defeated the Shang ruler in a decisive war in Muye. He founded the unified Western Zhou Dynasty (1046-771 BC) and became the common ruler of vassal states. When his successor, King Cheng, took the throne at an early age, Duke Zhou assisted him in governing the empire. Survivors from the capital of the Shang were relocated. A new capital was constructed at the location considered "the center under heaven". The new capital of Luoyi, also called "Chengzhou" or "Xinyi", was grand in scale and had a neatly-designed layout. The king predominantly resided here, receiving officials and vassals and hosting significant events such as sacrificial rites, title conferrals, and war announcements. Luoyi stood as another pivotal center of royal authority alongside Fenghao, the official capital of the empire.
