The Santegian Rebellion was a war that lasted from 1617 to 1619 in the continent of Asul. In the beginning, it involved the Principality of Evreux and two noble Houses that opposed its rule: House de Savin and House de Castro. Following the declaration of war, a military alliance was formed between the Kingdom of Santegia (formerly the Duchy of Savinia and Barony of Castrov) and the majority of the world’s nations; collectively known as the Second Axionite Coalition. The Principality of Evreux was supported by the Holy Orenian Empire.
In 1618, the Holy Orenian Empire began their offensive on the Duchy of Savinia in a small town of Castell, where the Coalition was victorious. Small skirmishes occurred in the proximity of both capitals for a year before the Coalition launched a siege to the County of Trier in 1619.
The war concluded in a peace treaty signed following the Siege of Trier. The Holy Orenian Empire agreed to issue a formal apology, give 70k mina to the Coalition, and cede the entire Principality of Evreux to the Kingdom of Savinia.
The Rebellion altered political domains in Asul. The Kingdom of Santegia increased their land to cover the County of Trier and the former capital Aleksandria, along with the rest of Evreux and strengthened their status in the world. The Principality of Evreux was dissolved and their ruling noble House of Halcourt established themselves in the Crownlands in Tahn.
The beginning of the conflict was overshadowed by a crossfire between House de Castro and House Baden that had lasted for years before the war began. As Courland dissolved into the Principality of Evreux in 1615, a year after Holy Orenian Empire reformed, many noble Houses were left with uncertainty as their loyalty was put to a test. The newly founded Principality of Evreux expected noble Houses within its lands to swear fealty to it, while the Duchy of Savinia sought to overthrow the new Halcourt regime.
Abdes de Savin and Elias de Castro were summoned to the palace of Aleksandria to discuss their vassalization to Evreux. A heated argument took place that resulted in blades being drawn. This incident then led to the death of many Evreuxian guards as well as Frederick Staunton-Baden. The De Savins and de Castros attempted to coup the city, although abandoning said endeavor in the process
Following the attempt of a coup, The Principality of Evreux denounced both Houses for rebellious actions, and thus the Emperor of Oren, John V, ordered them to relinquish their titles within Evreux and leave their land before the Imperial army would arrive to deal with the matter. As de Savin and de Castro resisted this order, a stage for war was set.
