History of Dericania

The history of Dericania is primarily related to the history of Levantia as well as that of both Great Levantia and the Holy Levantine Empire, the latter of which originated out of and was based in Dericania. While being home to a diverse number of southern Levantine peoples and ethnic groups, much of the history of Dericania in recent centuries has dealt with questions of Derian identity, which became a primary driving factor in world history and was an underlying cause for both the Second Great War as well as the earlier establishment of Burgundie as an independent nation.

Pre-conquest Dericania
The historiographical term "pre-conquest Dericania" refers to the period prior to the arrival of the Adonerii and subsequent rise of Great Levantia.

Gallawa
Gallawa was a large confederation of Christianized Gaelic tribes and kingdoms that existed in the north of modern Dericania and south of modern Fiannria from the late 4th to 8th centuries AD. Gallawa was originally conceived as a loose alliance of Gaelic polities which had both broken into and settled Great Levantia from the north, those who had lived as foederati subjects in specific lands of Dericania, and a smaller number of mostly uncontacted tribes living in the hills and deep forested parts of northeaster Dericania. The alliance seems to have been intended as a means to consolidate Gaelic holdings in previously Great Levantine lands, but the alliance persisted beyond the latter's collapse. Gallawa supplanted Great Levantia as the major power in Dericania by around 450 AD, and its mandate switched from defensive to offensive, expanding its borders and incorporating other tribes under its sway by force of arms. Increasingly, the confederate nature of the alliance became centralized under the control of a family that would become known as the Conine dynasty, who were responsible for leading Gallawa through the collapse of the Levantines.

Gallawa experienced a major population boom at the end of the 7th century and began rapid and aggressive expansion, particularly against the Latin League and Hištanšahr, the latter with limited success. Following decades of skirmishing and raids, King Conchobar lead the armies of Gallawa west into the former heartlands of Great Levantia. Although initial successes by the Latin League under the leadership of Gaius Julius Cicurinus slowed Gallawa's advance, his replacement by the Latin League resulted in its complete destruction as Gallawa overcame most of the Latinic cities in the Valley. Following his peaceful seizure of Urceopolis, Conchobar reformed Gallawa into the Levantine Empire, which would be ruled by the Conine dynasty for the next century and a half.

Eastern Kingdom of the Levantines
In 917, upon the death of the Emperor Brian III, the Levantine Empire under the Conine dynasty was partitioned into three parts, roughly corresponding to modern day Urcea, Carna, and Dericania, with the latter portion known as the Eastern Kingdom of the Levantines. Passing from the Conine dynasty to the Leonine dynasty, King Leo, reformed the Holy Levantine Empire in 965 with his conquest of the Southern Kingdom of the Levantines, reunifying most of the realm and receiving subsequent recognition of the Pope. Historians debate when the name "Dericania" entered common use for the realm, but the "Eastern Kingdom" nomenclature was largely extinct by the late 11th century. The Kingdom of Dericania resulted from this shift, and would continue to exist until the end of the Empire in the 20th century.

High Medieval Dericania
While the Emperor of the Levantines used Dericania and its crown possession, Corcra, as a successful base of power from the 10th to the 14th century, the Kingdom mostly devolved into an area with the least central authority in the Empire by the 1400s. Several reasons are cited for the decline in crown power, but the fall primarily came the demise of the dependent on Imperial support and the rise of hundreds of varied dynastic estates made the Kingdom administratively unwieldy and difficulty to govern.

Renaissance Dericania
While several attempts at reform were made in the 1490s, lack of central authority was permanently established because of the. Despite its lack of tangible political authority, Dericania was by far considered the most prestigious of the constituent Kingdoms of the Holy Levantine Empire, and a majority of Emperors of the Levantines were elected from Dericania.

During the Great Confessional War, the lands of Dericania were ravaged by war. Significant outbreaks of disease and widespread famine were a result of the conflict, greatly weakening Dericania and making most of the Kingdom significantly poorer. Many nobles and lords lost their fiefs and significant amount of territory changed hands during the Dragonnades as Protestant families were displaced by those loyal to the victorious Holy League.

Early modern Dericania
During the 19th century, the rise of Burgundie and the First Fratricide lead to chaos and disorder in Dericania that would continue until its demise in the 20th century.

Deric Republic
The Deric Republic was a provisional formed during the first phase of the Second Great War in order to unite the various factions fighting for independence from the Holy Levantine Empire and establishment of a Derian state. Despite consistent infighting between the disparate factions that comprised the Republic, it successfully managed to unite much of the former Kingdom of Dericania's industry and militias into a coherent war effort. The Deric Republic began to descend into infighting in 19XX-19XX, and the faction of the Derian nationalists opened negotiations for a peaceful settlement with Urcea and the remainder of the Holy Levantine Empire. With the Royal and Imperial Army on the advance in the face of a rapidly deteriorating state, the Deric Republic agreed to dissolve itself as part of the Treaty of Corcra, the centerpiece of the peace ending the Second Great War in Levantia. Following the signing of the treaty, the territories of the former Kingdom of Dericania and Deric Republic descended into the Third Fratricide between pro- and anti-treaty forces, with the pro-treaty forces forming the Derian National Congress after the Republic's dissolution.

Post-War period
The Kingdom of Dericania was dissolved with the Emperor of the Levantines relinquishing authority over it in 1935, leading to a period of significant domestic tumult and infighting known as the Third Fratricide. Following the end of the Second Great War, the former parts of the Kingdom of Dericania reformed into the Deric States, a loose confederation of many former states of Dericania which had consolidated during the war.
