The situation in Dailamy wasn't caused by the civil war--not exactly. What starting it was a coup.
A military general or something seized the throne and tried to kill all the successors. One of the children managed to run away, however, although their whereabouts were unknown. Thus, a conflict between those who were loyal to the crown and those who stood behind the general ensued.
Normally, people were prone to side with those opposing monarchy, because it was a symbol of oppression. But what difference would it be if the new reign oppressed the people even more? Quite a few aristocrats stood against the General, even if they did it for their own benefit. Rallying with Marchioness Indria as the lead, they fought with the one supporting the dirty crown, while looking for the lost royal blood.
