What I mean is are there any factions that you always help and leave alone? Mine would have to be the Swiss. Being nice to them comes in handy when your facing the a Golden Horde army 30,000 strong and they send over 10,000 units of swiss armoured pike-men and swiss halberids to aid in your battle(yes,it happened to me). Also since they start out so small I'm there to protect them. That damn HRE is so mean to them. So, what is your favorite faction you always allie with every game and help out?
