What Is Spring and Autumn Period?
Spring and Autumn Period (770 BC — 403 BC) was also the first half of the Eastern Zhou Dynasty (770 BC — 256 BC) when kings of the Zhou Empire gradually lost power, land, and lords of vassal states kept competing for hegemony.
This was also an era of great minds when many great philosophers formed their theories, such as Lao Zi, the founder of Taoism and writer of Tao Te Ching; Confucius, the founder of Confucianism; Mozi, the founder of Mohism; Sun Zi, the writer of The Art of War.

Why Is It called Spring and Autumn?
This period is named after a historical book, the Spring and Autumn Annals that Confucius wrote.
Spring was the season of planting and holding sacrifice ceremonies, and Autumn was about harvest and wars.
Therefore, the most important events in ancient China happened in the spring and autumn.

Brief History of the Spring and Autumn Period
After Ji Gongsheng lost the original Zhou capital and departed, the Western Zhou Empire stepped into another stage. Many vassal states fought against each other and nomadic tribes to occupy more land and people.
Lv Xiaobai, the Duke Huan of State Qi, flourished his realm and became the first mighty overlord in this period. After his tragic death, Lord Ji Chonger, the Duke Wen of State Jin, gained hegemony over the nation.
Decades later, some other ambitious overlords gained supremacy, while large numbers of small states were annexed, and bigger ones started to declare independence from the Zhou Court.
