Kingdom of Dericania

The Kingdom of Dericania was a constituent Kingdom of the Holy Levantine Empire, and for much of the Empire's existence it was the seat of the Emperor of the Levantines in Corcra, where the Imperial Diet and Collegial Electorate met. Characterized by dozens, sometimes hundreds of principalities, the Kingdom of Dericania drove many of the political concerns within the Empire during the through the , including during the Great Confessional War, the Caroline Wars, and finally during the Second Great War, where various nationalists, liberals, and socialists attempted to achieve Derian nationhood, beginning the first phase of the conflict. These groups formed the Deric Republic to replace the ancient Kingdom apparatus with a unified wartime state.

Nomenclature
The Kingdom as a distinct entity began as the "Eastern Kingdom of the Levantines", which remained the official name of the entity from its establishment in 917 until the late 11th century. During this time, it was popularly referred to in Urcea and elsewhere by Gaelic people as the "thoir" land, or the eastern land. By about 1000, the Kingdom was said to be "thoiric", or "eastern", which developed by 1050 into the term for the region "Toricania" and eventually "Dericania" as a derivative. The Kingdom was officially referred to this name by about 1100 onwards, though the "Eastern Kingdom" title would remain in limited use until about 1300.
