In the first half of the Eastern Zhou dynasty, the Spring and Autumn periods were the names given to times before war was rampant. The Annals of Spring and Autumn was a chronicle of the time of Lu, an influential cultural epistle.
The period was known as Chunqiu (Spring and Autumn). In this time, the familial relationship among the nobles was gradually diluted and perhaps this enabled the enmity between states to fester. The Spring and Autumn, Chunquiu period existed from about 771 until 476 BC
The spring and autumn period of the ancient China refers to the period between 771 to 476 BC. It corresponds to the first half of Eastern Zhou dynasty. This time period is named after a book called the spring and Autumn Annals, which was a chronicle of the state of Lu. This period preceded the warring state period of the latter half of Eastern Zhou dynasty.
The tradition at the time was associated with Confucius. It was a time of turbulence and change in the economy, politics and military affairs. China’s feudal system of fengjian became irrelevant.
