So, I just started a run as Matilda di Canosa, Duchess of Tuscany. After a successful plot to steal the duchy of Lombardy and another plot to steal Verona, I formed the Kingdom of Italy (and then the emperor gave me a couple vassals to make me happier to get me out of the independence faction. He shouldn't have bothered since I wanted to be able to form E_italia as soon as I got independence, but it made getting the territory easier. My problem is that I forgot to switch to Primogeniture before forming k_italy, so now I have to spend inordinate years waiting to increase my crown authority so I can go primogeniture. Any suggestions?
