Knonfoda - as you see it worked

By just raising taxes you made extra 11K without effort. And that is full legion - good to send anywere you need. The pop decline is not a problem. Cities with very high taxes still can grow up to 30 000 or more population. And as long as the city is not going to rebel it is fine. That is why you need hapiness buildings - the more the better. Of course you must built cheap ones first. The garrison must be at most one general and one cheapest available to hire unit. If you need more garrison to pacify town - do not raise taxes, it is not worth it.
And Centrius is right - if you want to have historical wars - you better download this force diplomacy mini mod. Once comp starts war - it will not end it... However it will be less difficult than to fight on multiple sides and decide which way to expand

But since you enjoy historical expansion - it is a must for you then
