Fall of the Western Zhou
Nomads sack the capital, and the Zhou move east to Luoyi

The Quanrong tribes, allied with disaffected nobles, took Haojing and killed King You. His heir moved the capital east to Luoyi (Luoyang). The Eastern Zhou kings became figureheads, and the Spring and Autumn period began, when rival states effectively ran the country.
