Haedong Province

Haedong Province (Zhenian: 해동도) is a Zhenian province located east of Zhenia's Danguk Peninsula. It consists of the Haedong Islands and surrounding islands, and is separated by Zhenia's Gyeongcheon and Gwandong provinces via the Strait of Chungmu. "Haedong", the name of the province, literally means "land east of the city", a term reflecting its location as the easternmost province of Zhenia and a separated entity from the Zhenian mainland. It spans over an area of 39,595 square kilometers (15,287.6 square miles), with the eight major islands of the Haedong Islands constituting around 95.5% of the province's total land area.

Having been populated by a mix of Dan Zhenians and the Haedong people since 3,500 years ago, what is now Haedong Province retained a separate history from the mainland, islands being ruled by a set of chiefdoms until they were unified under the Kingdom of Haedong in 104 AC. The Kingdom of Haedong maintained tributary relations with kingdoms in the Danguk Peninsula, being granted autonomy in exchange of their monarch being installed by that of the Eastern Zhen, Daehwa and later Shindan, confirmed by records in which Haedongese princes attended the Shindanese royal court in 931, in exchange of. Haedong fell into the Shindanese sphere of influence following the suppression of the Revolt of Jinhaegwan in 944, while it was formally annexed into Shindan under King Munjong in 986. Haedong has since remained within centralized Zhenian rule, its importance as a key gateway to the east spurring its growth over the years. While the Haedong ㅡMandate was temporarily established by the Allied High Command following Zhenia's defeat in the Second Great War, it was returned into Zhenian control in 1546.
