The Sosphene Crusade (Eufez)

Cornelia became a principality of the Baden Empire and received significant gils in payment, protection insurance, tax relief, and access to the Empire's bank reserves. Cornelia was also allowed any amount of naval support to secure its maritime borders, and the empire provided extensive training to its officers and soldiers in preparation for possible conflicts with neighboring countries. The arrangement was ultimately largely financial, and allowed a declining Cornelia to enter another renaissance of prosperity and growth. The transitionary process was slow and cautious; it took until 1344 to officially bring the entirety of Cornelia major into the empire. Cleber IV visited Cornelia and was welcomed by Cornelians with much fanfare, and Cornelia became a part of the Baden Empire's "New West". With the addition of the eastern provinces, the Baden Empire again became the largest nation on Eufeza.

Cornelia was unable to secure the support of the Sosphenes, and therefore the nation was divided upon joining the empire. Some Sosphenes expressed interest in joining the rest of Cornelia in its decision. Sosphena at this time was not recognized by the official Cornelian government, and was largely seen as a land of savages.

These tensions ultimately erupted when Cornelia attempted to force Sosphene to join the principality in 1473. A war broke out between the Dukedom and the Sosphene throne. The war resulted in Sosphena being absorbed into a unified Cornelian kingdom.
