I took a slightly different approach to setup a game - but all the principles around governors, amenities, are still very useful for making sure you lose loyalty when the time comes. Your best bet is to work on rapid expansion while staying in a golden age for the time being. Switching to Deity and it varied from 2-4. When playing on Immortal difficulty, I only had 1 city rebel each time. This achievement is a bit trial and error. It will not count towards the achievement. 2 rebel on entry turn and 2 rebel after). They cannot rebel throughout a Dark Age (ex. All 4 cities must rebel at the same time entering a Dark Age. I believe this increases the chance for rebellion as the 4 cities that rebelled had that issue.

Avoid upgrading those cities and try to have an amenity problem. I noticed that monuments can sometimes prevent a city from rebelling due to the +1 loyalty boost. Do not build monuments in your cities that are on the edge of your empire. Cities with no governor rebel more often than those without. Do not disregard the other mechanics as loyalty factors do come into play. If this occurs, I suggest restarting and focusing on settlers for the first 100 turns. This means you will have to keep up close to the mid-end of an era tree before they get into theirs for a chance to not go into a dark age before you have 10 or more cities established. This was entirely due to the Deity AI tech and culture rush. This achievement popped when I entered the Modern Era in 1490AD. The 4 cities that rebelled were on the edge of my empire and not central. (Not sure if this affects the game mechanic or not). I built about 10 cities, 4 of which were on another continent. Your points do not carry over and you will actually lose those benefits in the next era. However, try to not go over the limit, (ex.

Starting off, focus on filling your golden age meter through exploration and fighting barbarians. The Cree are relatively peaceful so you do not have to worry much about your military, however, they will research and culture rush you into new eras due to Deity AI boosts.

I played as Russia and removed all players except the Cree I did unlock this on Deity as it seems difficulty affects how many cities rebel. I am unsure if I am the first to unlock this but this is how I got it. This achievement can be a bit rough if you do not know the Civilization VI mechanics too well.
