City garrison: How do they affect happiness?

[Owen]

This thread is a result of my newbie mistake in my first and current RTW game of not enslaving or exterminating the population of Carthage when capturing it as the Julii. As a result, I am finding it hard to keep it happy with a population of about 18000 (IIRC), even at low tax and what I thought was a large garrison but turns out to still get nowhere near the maximum. I realise part of the problem is culture difference (difficult to deal with easily when part of the solution is to destroy an Awesome Temple of Baal), along with the possibility of spies inciting unrest.

Here's what I know:
- There is a hardcoded 80% maximum happiness from garrison
- The larger your population, the more troops you need for the same percentage effect. Whether this is linear with the exact population value or whether it steps with city size, I do not know

Here's some possible other factors that I just thought up off the top of my head:
- Garrison effect is reduced by wrong culture
- Garrison effect increases when you upgrade your governor's building
- Your governor's rating in command, management and/or influence
- Garrison effect depends on distance to capital
- Garrison effect depends on some inherent value of different troops types
- Garrison effect depends on how long the armies have been in place
- Garrison effect depends on any one of a long list that would make this post long and boring

So, does anyone have any thoughts, or just a link to a previous thread?

Thanks

No matter. In case anyone else was wondering, thanks to this handy post (https://forums.totalwar.org/vb/showthread.php?p=599476#post599476) by therother, I found my answer. :)

It is worth remembering that only the number of men in the garrison counts, so don't use your Urban Cohorts as garrison - peasants do just as well.

1 unit of peasants will keep 1000 people happy. since you are Roman peasants are the only unit you can have that is large enough to do that. Just about all other factions or all of them at least have a semidecent unit that is the same size as a peasant unit.

So to keep the city in order you need 18 units of peasants.

Your culture penalty is due to the Carthiginian buildings in that town. Build all that you can. If there is nothing left to build you can raze carthiginian buildings and build Roman ones.

Since it sounds like the problem is only going to get worse heres what I'd do.
Jack the taxes to very high let them revolt and boot you out. Then retake the city extermianate them and that should buy you the time to improve the city. Carthage is an easy city to hold if you can kill the culture penalty

Besides, I think Carthage has the highest growth rate in the game. If it's not the highest, I bet it's one of the top three. You can exterminate it and it will be back where it was before in record time.

Yep.

The greater bulk of the growth rate comes in the form of "Food Imports" (Grain in sacks on the Pop growth area in settlement details) and a strong base level farming upgrade.

Basically Syracuse, Carthage, Memphis and Alexandria. All have Grain as a trade resource, and this gets exported to your other lands to help growth... As well as being consumed at home. This where the squalor gets out of control, because even at Very High Taxes with a full garisson your going to have it tight keeping a lid on the growth rate and public order.

Essentially having both Syracuse AND Carthage will make your situation worse as the Food Exports from both will Cause your Population Growth to expand rapidly...

Grain is why Syracuse and Carthage are such a popular target... it is also the reason why Egypt always develops into a superpower.
