January 17, 1446, of the Holy Calendar, the Castel family declared war on the Bold family in the name of independence and the recovery of their legal territories.
January 18, the Bold family also declared war on the Castel family for the purpose of quelling rebellion and the lawful deprivation of titles.
Thus, the Castel-Bold War officially erupted.
At the same time, the Third Prince Philip, in his capacity as the Duke of Bold, assured the nobles of the Northern Land that this suppression was solely targeted at the Castel family.
As long as the Northern nobles remained neutral, they could avoid the spread of war, and their titles and lands would be preserved.
Furthermore, those who swore loyalty to the Bold family were offered numerous favorable conditions, including a reduction in the vassal contract tax.
