In 589BC, Qi was defeated by Jin. In 579BC, the four great powers of Qin (west), Jin (center), Chu (south) and Qi (east) met to declare a truce and limit their military strength. In 546BC, a similar four-power conference recognized several smaller states as satellites of Qi, Jin and Qin.

Warring States period - Tian Qi

Early in the period, Qi annexed a number of smaller states. Qi was one of the first states to patronize scholars. In 532BC, the Tian clan destroyed several rival families and came to dominate the state. In 485BC, the Tian killed the ducal heir and fought several rival clans. In 481BC, the Tian chief killed a puppet duke, most of the ruler's family, and a number of rival chiefs. He took control of most of the state and left the Duke with only the capital of Linzi and the area around Mount Tai. In 386BC, the House of Tian fully replaced the House of Jiang as rulers of Qi. In 222BC, Qi was the last of the warring states to be conquered by

, thereby putting an end to the wars and uniting China under the Qin Dynasty.

'', there were nine distinct cultural regions of China, which are described in detail in this book. The work focuses on the travels of the titular sage, Yu the Great, throughout each of the regions. Other texts, predominantly military, also discussed these cultural variations. One of these texts was ''The Book of Master Wu'', written in response to a query by Marquis Wu of

on how to cope with the other states. Wu Qi, the author of the work, declared that the government and nature of the people were reflective of the terrain of the environment in which they inhabited. Of Qi, he said: While visiting Qi, Confucius was deeply impressed with perfection of performance of Shao music 韶 therein.Analects, 17 ("Shu er"):14. During the Warring States period, Qi was famous for its capital's academy Jixia, renowned scholars of the era from all over China visited the academy.

The state of Qi was known for having well organized cities that were nearly rectangular in shape, with roads that were neatly knit into a grid-like pattern. The palace was strategically positioned facing the south. To the left (eastwardly direction) of the palace resided the

, to its right (westward) the temple of the gods, both one hundred paces away. This ensured that balance was achieved. In front of the palace was the court also one hundred paces away and to the back of the palace was the city. This type of layout influenced greatly the way cities were designed in subsequent generations. Smaller cities known as ''chengyi'' (城邑) were abundant throughout Qi. They typically stretched 450 meters from south to north and 395 meters from east to west. The perimeter was usually surrounded by a wall with the living headquarters situated within and a nearly perfect square-shaped courtyard occupying the center.
