The Five Hegemons of the Spring and Autumn Period

In the early Spring and Autumn Period (770 - 476 BC) the Zhou Kingdom was divided into over 100 vassal states, all squabbling over land and population. Strong states annexed weak ones and contended for hegemony over all the others. During this period, Duke Huan of Qi, Duke Xiang of Song, Duke Wen of Jin, Duke Mu of Qin and King Zhuang of Chu became the hegemons in succession, and were called the "Five powers of the Spring and Autumn Period".

Some historians rank the "five powers" as Duke Huan of Qi, Duke Wen of Jin, King Zhuang of Chu, King Helu of Wu and King Goujian of Yue.
