King Youwang Tricks Regional Lords-Ending
Youwang became so fond of Baosi that he made her the queen and her son the crown prince, after deposing Queen Shen and her son Prince Bofu. Upon learning this news, the queen's father, who ruled the fief of Shen, rose up in collaboration with Quanrong against the king. In 771 BC, Quanrong warriors besieged Haojing. The panicking king ordered fires lit at the signal towers. However, remembering the king's earlier dirty trick, no one came to his rescue. Sparsely defended, Haojing was soon overrun by invaders.
Youwang fled to the foot of Lishan Mountain, where he was killed. When they realized that the attack was real this time, the regional lords rushed to the capital, but it was too late. They had to negotiate with the lord of Shen and enthroned Yiju, son of Youwang, who was known as King Pingwang.
Pingwang moved the capital city to Luoyi(today's Luoyang, Henan Province), marking the end of the Western Zhou, and the beginning of the Eastern Zhou Dynasty (770-256 BC). The Eastern Zhou Dynasty was divided into the Spring and Autumn Period (770-476 BC) and the Warring States Period (476-256 BC), during which feuding states contended with each other against the backdrop of a weak central authority.
The Spring and Autumn Period was characterized by unrelenting wars and drastic social changes. It was said that there were over 140 states at the beginning of this period. After years of battles and annexation, only a handful of powerful states survived. These major powers continued to fight against each other for dominance. The five regional rulers who eventually established dominance were known as the "Five Overlords of the Spring and Autumn Period."
One version of the list of Overlords is: Duke Huangong of the Qi State, Duke Xianggong of the Song State, Duke Wengong of the Jin State, Duke Mugong of the Qin State, and King Zhuangwang of the Chu State. Another version is: Duke Huangong of the Qi State, Duke Wengong of the Jin State, King Zhuangwang of the Chu State, King Helu of the Wu State, and King Goujian of the Yue State.
