Does the AI hate germans by default?

I must've put a good few thousand hours played into this game, and I'm currently working on my first real campaign as Germania. Previously I tried starting one at VH/VH after getting powerdrunk on playing the Brutii, but that proved hard if not impossible after a few years as I couldn't get enough money and population going no matter what. My new campaign is set on M/M, but so far I must say it's been all but medium...

Right at the start I decided to play it cooler than my previous campaign, trying to stay friendly with my neighbours and slowly expanding east and south by taking the rebel settlements. This worked for, well, perhaps two turns before the Gaul and the Britons decided to gang up on me. Luckily the germanian forces are some of the best in the game - by far the best barbarians - so I could push them back with ease, but seeing as my other borders were to hostile rebels I lost all forms of trade being at war with my western neighbours. Also what little populationgrowth I managed to get was put into retraining troops, and the poor rebel provinces I conquered didn't really provide enough income to supply the forces I needed to hold my western borders.

As time passed I grew weary of the constant attacks on my borders and decided to push westwards, and took Samobariva from the Britons and Alesia from the Gaul after some fierce battles. This did little to scare my friendly neighbourhood barbarians off though, and they both kept attacking me pretty much every turn. The Gaul had also managed to expand to Helvetia just south of my border and started sending large armies from Patavium against my soft underbelly. Reacting to that and taking that province and subsequently Patavium from the Gaul is what really started the problems...

Suddenly I didn't only have to face constant battles on my western borders, but the Dacians also attacked on the eastern front. Constantly. Not saying they sent any decent armies, but small forces of 1-10 units kept hitting my small eastern towns and took quite some defending to hold. In the south the Gaul fought desperately to take Patavium back, and if that wasn't enough suddenly huge armies of the Julii were at my doorstep. Of course they wouldn't fight the Gaul for anything in the world - they'd managed to only gain Segestica or whatever that little rebel settlement northwest of their startingposition is called - and started hammering Patavium with all they had, mounting up to 1 full army every other turn. And obviously the other romans decided to have a piece of the pie and declared war with me as well, all the factions.

Right now I'm having quite a blast defending each border and being at war with no less than seven factions (personal record by the way). Soon that'll be stretched to eight as I have ten units of thracian falxmen standing in my backyard waiting for... well, some queue to attack. My economy is not very stabile at all and relies heavily on me plundering a new town every five turns or so. Trading is close to zero with other factions as my only "friendly" border is my easternmost province against Scythia, and they have been nosing at my fortifications the last few rounds as well.

So, what I'm curious about is if anyone else is finding the germans to be this impopular? I can't recall having nearly this much opposition in any previous campaign, and no matter how many diplomats I send to offer sweet deals and how many of their armies I crush none of the seven factions will accept a ceasefire.

Kind regards
