An empire strives for stability, influence, and its people. All of these resources must be managed for your empire to run like a well-oiled machine. Balancing these is no easy task, especially when it comes to Stability.
Each city has its stability and numerous factors can influence this level. Depending on your Stability, it will provide a bonus based on the percentage of stability that it has. The worse your Stability gets, the more our city will suffer. If your Stability gets too low, you may be facing a revolt.

Should your people revolt, a portion of your population may separate from the city and become independent people who may try to take the city for themselves. To prevent this, you can take measures against your Stability from getting too low. One of these ways is to build. Military Structures, Landmarks, and Defensive Infrastructures will all improve Stability.
In addition to these, you can also hold Ceremonies to increase Stability. On occasion, some Narrative Events, Tenets, or Civics will also increase your Stability. These can also influence the ideology of your empire which adds another factor to consider. As a result, you are faced with choosing between your beliefs and your city.
