Hey Guys

i started of as Lord in the Vale, after o couple of years, i managed to get more provinces and final overtake a Highlordship from my liege.

I tough taht the highter new titel woud raise the maximum of own Provinces, but it stayed one. So from my three provinces i had to give away two to vassals.

How can raise the max amount of my own land?

You need higher stewardship, or you can change your succession laws (Gavelkind I believe increases your demesne more than Primogeniture). Mostly just increase stewardship, though.
