"Yongzhou" in Chinese characters
|Literal meaning||Harmonious Province|
From the Western Zhou dynasty to the Western Jin dynasty, the name Yongzhou was applied to the area around the imperial capital, whether it was the Wei Valley (also known as Guanzhong) or the territory around Luoyang. When Emperor Wu of the Western Han dynasty created the 13 inspectorates (刺史部; cishi bu), the western part of Yongzhou became part of Liangzhou Inspectorate (凉州刺史部) and its eastern part was governed by the Colonel-Director of Retainers (司隶校尉).
When Emperor Wu of Han relocated the Han capital to Luoyang, he briefly established a formal Yong Province. However, he abolished it soon after.
In AD 194, the Eastern Han government established a Yongzhou Inspectorate overseeing the commanderies of Wuwei, Zhangye, Jiuquan, Dunhuang, and Xihai (西海) west of the Liang River. The inspectorate seat was at Guzhang (姑臧). In the year 213, the Liangzhou Inspectorate was eliminated and the commanderies of the Three Guardians (三輔, sanfu) were absorbed as part of Yongzhou Inspectorate.
In 220, amid the Three Kingdoms Era, the Wei government reconstituted the Liangzhou Inspectorate from the eight commanderies of Yong Province west of the Liang River. Yong Province was established as an inspectorate to the east of Liangzhou and the Yellow River, near the commanderies of the Three Guardians near the capital of Chang'an, with the inspectorate seat at Chang'an.[clarification needed]
Former Qin provinceEdit
Southern & Northern geographical regionsEdit
During the time of rival dynasties in the Southern and Northern Dynasties period, the Northern Wei, Western Wei and Northern Zhou dynasties in the north referred to Yongzhou as to the environs of Chang'an with its government seat at Chang'an, while the Eastern Jin dynasty and the Southern Dynasties in the south referred to Yongzhou as the environs of Xiangyang.
After the reunification of China by the Sui dynasty, Yong Province's administrative centre was permanently set at Chang'an. During the Sui administrative reforms in 607 to transform the provincial system into a commandery system, Emperor Yang renamed Yong Province to Jingzhao Commandery (京兆郡).
