Anxi Protectorate established at Jiaohe
The Zizhi tongjian records establishing the Anxi Protectorate at Jiaohe City and leaving troops there.
What this does and does not establish
Juan 195, line 190, pinned revision 1554157. Jiaohe in the Gaochang oasis is the explicit site of the action. The preceding debate records Wei Zheng's opposition to annexation and the emperor's rejection of it.

- Kind of record
- Placed in a year. A source places this in one year. It is listed under that year; no day precision is invented.
How it is dated
- Date reference
- Tang Taizong, Zhenguan 14, ninth month, yimao
- How we use it
- Year-level placement is limited to the dated source entry.
The date reference is this project’s reading of the source’s date. It may give an era name, a reign or a calendar in a normalised form rather than in the source’s own words; the dating notes say what the source prints.
Dating notes from the research record
Read zztj195.wikitext lines 182–204. The ninth-month heading occurs earlier in line 190; the preceding surrender is dated guiyou under the eighth-month sequence. Calendar headers in sinica-639-12-31.html and sinica-640-12-31.html identify Julian 639-12-31 = Tang Taizong Zhenguan 13, 12/2, and Julian 640-12-31 = Zhenguan 14, 11/13. The ninth month follows explicit autumn eighth month and precedes intercalary month ten, placing it within Julian 640. The subsequent month-eleven jiazi/guihai new-moon dispute is outside this event's month.
File names and line numbers in these notes, and in the limits above, refer to the project’s retained copies of the cited sources. Names such as calendar_headers are the project’s calendar look-ups, and “the investigator” is the research step that prepared the record.
