HTF are you supposed to conquer another continent around medieval/renaissance era? There's a continent with a rival empire on it, I land lots of crossbows and pikemen on it, take a city.. "rebels in 3 turns". Fine, I try something else, I raze that city, and 2 more cities, building my own cities instead with settlers. "rebels in 11 turns". And I already have the "war guy" governor there, the military-card that gives +2 loyalty for garrisoned cities, the green-card with +2 loyalty for cities with governors, AND I bought a monument (+1 loyalty). And it's my own city that I established, no conquered penalty. Literally no matter what you do, it is impossible to stack enough loyalty to keep a city,. That makes no sense.
