The war was caused by the several provinces that refused the Port City of Tarith's call for allegiance. In defiance, they murdered Tarith's diplomats and declared Tarith as an arrogant province who abused their influence to force the other provinces to ally themselves to Tarith for fear of being destroyed if they refused. Therefore, the dissidents gathered ratified themselves with a new charter, declaring their alliance to each other and formation of the Legional State of Saulos. Tarith also did this, calling themselves the Monarchy. However, the Monarchy had all the rulers of the provinces as Regents and Generals of their combined army.
