Town · Dai Viet under Ly Cao Tong · as at first light, 1 January 1200

Duy Tinh (Thanh Hoa)

The campaign board's seat of the Thanh Hóa circuit under the Ly, on the coastal plain near Hậu Lộc rather than at the modern city.

Thanh Hóa is the second country of the kingdom: its own rice plain, its own aristocracy and its own soldiers, and it produces dynasties (board). Lý Thường Kiệt governed it for over twenty years from 1082 and left inscriptions to prove it (board; the Linh Xung stele of 1126 is the best documentary anchor). We could not fix the name Duy Tinh or the seat in any source we could open.
