History
In 660, when a joint Silla-Tang alliance destroyed Baekje, the Tang dynasty established a protectorate named Ungjin Commandery in its stead. Furthermore, the Tang emperor offered to Munmu of Silla that he take over a proposed protectorate called the "Great Commandery of Gyerim", which was refused.

Following the offer Silla launched a surprise attack against the Tang forces and destroyed the Ungjin commandery. Over the course of several battles Tang forces would be driven north of the Taedong river by the Silla army.

In the south of Silla another administrative subdivision named Jimizhou was to be set up. Munmu of Silla was to be nominated as first "commander" After that the position was to be inherited by the line of rulers of Silla.
