In the 8th century BC, power became decentralized during the Spring and Autumn period, named after the influential Spring and Autumn Annals. In this period, local military leaders used by the Zhou began to assert their power and vie for hegemony. The situation was aggravated by the invasion of other peoples from the northwest, such as the Qin, forcing the Zhou to move their capital east to Luoyang. This marks the second major phase of the Zhou dynasty: the Eastern Zhou. The Spring and Autumn period is marked by a falling apart of the central Zhou power. In each of the hundreds of states that eventually arose, local strongmen held most of the political power and continued their subservience to the Zhou kings in name only. Some local leaders even started using royal titles for themselves. China now consisted of hundreds of states, some of them only as large as a village with a fort.
As the era continued, larger and more powerful states annexed or claimed suzerainty over smaller ones. By the 6th century BC most small states had disappeared from being annexed and just a few large and powerful principalities dominated China. Some southern states, such as Chu and Wu, claimed independence from the Zhou, who undertook wars against some of them (Wu and Yue). Many new cities were established in this period and Chinese culture was slowly shaped.
Once all these powerful rulers had firmly established themselves within their respective dominions, the bloodshed focused more fully on interstate conflict in the Warring States period, which began when the three remaining élite families in the Jin state – Zhao, Wei and Han – partitioned the state. Many famous individuals such as Lao Zi, Confucius and Sun Tzu lived during this chaotic period.
The Hundred Schools of Thought of Chinese philosophy blossomed during this period, and such influential intellectual movements as Confucianism, Taoism, Legalism and Mohism were founded, partly in response to the changing political world. The first two philosophical thoughts would have an enormous influence on Chinese culture.
