How to stop rebelling city?

[Cardboard]

Every 2-3 turns this one city i took during a war that has now ended would rebel and i would within a turn level it with artillery then march troops in but i cant liberate it to the civilization that owned it and i dont wanna raze it incase the enemy countries just build a new city there or what happened to one of my other cities on that continent is just any city i build other than the first one would just instantly rebel in 3 turns for no reason. Anyone know what i can do other than level the city every few turns?

The other city i created that rebelled had me malding bec it was the most american town ever, it was called Miami, it was populated from americans from my capital, it was prodestant and within 3 turns it rebelled then instantly joined a saudi country's nation. How could the most american people ever just leave america for the opposite of america.
It was like building your wife a whole house in a nice neighbourhood then she turns around tries to stab you then says she loves the neighbour and you are some poohead that never really liked u or knew you xD

Rebellion is based on the loyalty mechanic. Every city exerts pressure on itself and nearby cities based on its population, and if the pressure from other civs exceeds the pressure from its own civ it loses loyalty. When that drops to zero, the city rebels.
There are some other factors that influence loyalty as well; happiness, governors, grievances of the founder against the current owner, and military garrisons during occupation are the big ones.

But once you've made peace and had the city ceded to you, you don't get a benefit from a garrison anymore. If that city you hold is taking overwhelming pressure from cities of that rival you didn't take, there's not much you can do. You'd need to go back in time and take more cities during the war to actually solve the problem.
A city you found right up against a rival's borders will also be overwhelmed and flip away rapidly. You're not taking a big hit from grievances in that case, but the population pressure dominates. Pay attention to those warnings in the settler lens; if it's showing "-20", you can't hold it.

When you take over a city do you leave a unit garrisoned there? And do you send a governor to raise loyalty right away?

Ive managed to get it to 3 turns and ive sent one of my military governors and i always keep a unit garrisoned. I mean i can absolutely keep taking the city and its ig free xp every few turns but imma see if the governor can do anything if he even arrives in time but the nearby cities are giving -20 loyalty so not much i can do. Ill keep occupying the city until i have to raze it incase of a war on the continent.

Governors apply their +8 loyalty benefit from the moment they're assigned; that doesn't wait until they're established.

So, -20 from population; that's the cap. If the city's ecstatic (+6) and has your founded religion (+3) and a governor (+8), you're still at -3. A monument gets you to -2. Still more needed, or it'll flip away in 25 turns. Maybe a couple policy cards, maybe Victor's tier 2 promotion (which requires him to be established).

It is possible to beat that -20, if you have all the positive modifiers working for you. But you need all of them, and no extra negative modifiers like that grievance penalty.

If you've got the space you coould try plunking a city or two of your own withing loyajty range of this city, but outside the other civs loyalty range.
