Arthurian Civil War

The Arthurian Civil War was a major single-theater civil war in the Continent that erupted in the wake of the death of Emperor Lancelot. In essence, the war was fought against the forces of the usurper Emperor Mordred against those who want to return Guinevere back to her rightful place on the throne.

Meanwhile, with the attention of the Empire diverted, Algar, High King of the Empire of Saxonia, seizes the opportunity to gain territory from the Arthurian Empire.

The Coup
Upon Lancelot Arthur's death, his heir apparent, Princess Guinevere, takes the throne. However, her younger brother, Prince Mordred, leads a well-planned coup and takes the throne for himself, forcing Guinevere to flee. Mordred sees himself as the rightful heir by right of gender, despite being second to Guinevere in the lawful line of succession, and sealed his right by either bribing or assassinating his sister's supporters in the capital city of Camelot. Despite losing the capital city and the eastern portion of the Arthurian Empire, Guinevere managed to band the duchies of the western portion to side with her, sparking a civil war to take back her throne.

Defeat within the months
During the first month of the war, Emperor Mordred made the wise decision to create an Imperial Army, one loyal to the Emperor, in order to destroy the old feudal system's disorganization. During months after, Mordred and his cohorts manage to inflict some damage to the rebels forces due to the effectiveness of the Imperial Army and the many wealth he acquired to turn duchies against the Empress, the royalist forces were able to conduct many victories upon the rebel forces in many battles and sieges.

Within only a few months, the forces of Empress Guinevere were pushed right back to the south-west border of the Arthurian Empire, with the last stronghold before achieving complete victory is the city of Guinevere. Mordred, under his council's advisement, decided to wait it out in order to get his sister to properly recognize him as the true ruler of the Arthurian Empire. Despite this, Guinevere's dark and light elven allies conducted many guerrilla raids against Mordred's forces.

When Saxonian troops were spotted across the border, Mordred turned the majority of his forces to push back the Saxonians, leaving half a million troopers to guard the western portion. Algar's forces were stopped from going further from Lake Merlin, in between the Saxonian Empire and the Kingdom of Jorvik, and were brought to a bloody stalemate.
