Today I started a game playing as a count in the Byzantine Empire. I thought it would be fun to try and start as a small count and attempt to eventually become Emperor but I've run into some trouble already. The Empire has Medium CA which means I can't declare war on any of the other counts so I can't expand that way. I thought I could still expand through marriage but there's no countesses available that will accept a regular marriage.
Any tips?
