Overview

All Under Heaven came out on 28 Oct 2025. It extended the map to China, Japan, and Southeast Asia and added a title tier above empire, the hegemony. Dev Diary 172 says China is the only hegemony in the start dates. Uniting India or restoring Rome can create others. The title is h_china, with its capital at Bianzhou.
The hegemony uses the Celestial government. Dev Diary 172 says it builds on the administrative government Roads to Power gave Byzantium. The game text calls Celestial a bureaucratic form in which the liege appoints governors of two kinds, civilian and military. Civilian posts go by appointment, and merit is the deciding factor.
The Dynastic Cycle moves the hegemony through stable, unstable, and chaotic eras. A dynasty that wins the civil war of a chaotic era takes the Mandate of Heaven and restores the hegemony. The top rank also carries the top domain limit: patch 1.20.1.2 gives a hegemon 5, against 4 for an emperor.

Starts
867
The Tang hold the hegemony. The emperor is Li Cui, Emperor Yizong, born in 833. On patch 1.20.1.2 the realm counts 330 counties, vassals included, the largest on the 867 map. Dev Diary 172 describes the Tang as a once expansive dynasty already in trouble by 867.
The Autumn of Virtue bookmark seats Huang Chao, a landless rebel, and four commandants and governors who are vassals of China. Huang Chao's rising, from 875, is the blow the dynasty did not survive.
1066
The Song hold the hegemony. The emperor is Zhao Shu, Emperor Yingzong. The realm counts 267 counties, still the largest on the map. Great Liao and Xia hold the northern border.
The Song of Splendor bookmark seats the poet Su Shi as prefect of Meizhou and Qin Guan with no county at all. Yingzong died in January 1067. Shenzong and the reformer Wang Anshi follow.
1178
The Song still hold the hegemony, now from the south. The emperor is Zhao Shen, Emperor Xiaozong. The Song count 181 counties. The Jurchen Jin empire of Wulu Wanyan, Emperor Shizong, counts 190 and holds the north the Song lost in 1127.
The Heaven in Turmoil bookmark seats the Song officials Xin Qiji, Zhang Shi, and Zhu Xi, the Xia ruler Renxiao, and a Jin intendant in Henan. On the steppe the same year, Temüjin is sixteen.

Later impact

The Tang fell in 907. The Five Dynasties and the Song reunification followed, and the 1066 card is the Song before the northern loss. In 1127 the Jin took Kaifeng, and the Song court moved south. The 1178 map shows that division.
Temüjin, the 1178 steppe start, became Chinggis Khan. The Mongols destroyed the Jin in 1234 and the Southern Song in 1279, and Khubilai's Yuan claimed all of China. That is the path the Dynastic Cycle models: a chaotic era, a civil war, and a new house with the Mandate of Heaven.
Celestial careers run on merit and education. Confucian Education adds learning and opinion between holders. Burdened cuts monthly merit and governor experience. Former Emperor pays prestige and influence each month. The trait pages list the exact numbers.
