Transionia

Transionia is a term referring to the corridor-like region of Urcea east of the Ionian Mountains and west of the border of Dericania bounded on the south by Gassavelia and in the north by Ænglasmarch, consisting of the provinces of Eastvale and Burgundiemarch. These areas were historically outside the boundaries of Urcea and were considered integral parts of Dericania with small portions of this territory belonging to both Anglei and Gassavelia. Historically making up Dericania's western border with Urcea, the emergence of Urcea as the victor in the Third Caroline War lead to its annexation of these territories. The annexation was followed by waves of Ómestaderoi settling in the area, displacing large numbers of Derian people. Derian displacement was both state policy and incidental to war and conquest, creating large numbers of refugees who fled from Urcean rule. Consequently, the two provinces which make up Transionia today are largely populated by Urcean people and are relatively lightly populated compared to the rest of the country, but Eastvale does have the nation's largest minority of Derian people. The annexation of these territories by Urcea lead to a political crisis in the Kingdom of Dericania known as "le crise della dix" which precipitated the First Fratricide and establishment of Burgundie as an independent nation.
