When Emperor Youwang was on the throne, the court affairs were full of corruption. His people were not satisfied with his rule at all. Meanwhile, Zhou failed to defeat the rebellions then. Besides, Youwang awarded a woman - Bao Si as the empress and usually ignored the court affairs afterwards. As a result, the rebellion rose up to kill You Wang and the dynasty was over.
