Imperator: Rome tasks its players with maintaining the Roman Imperium over the course of decades and centuries, and though the first thing that comes to mind is, perhaps, aggressive expansionism, it's just as important to avoid any sort of internal strife, too.
Imperator: Rome Stability is a measure of your Imperium's internal stability and tranquility, and dictates various aspects of your control over the country. Down below, you're going to find out what those aspects are, and how to approach a desired increase in Stability.
How to Maintain Stability in Imperator: Rome?
Imperator: Rome Stability is the direct measure of how effective your Imperium's internal political structure is. It is dictated by the health of your nation, and the performance of your institutions, so it's a very handy tool for checking how well you're doing in regard to internal policy. Furthermore, Stability also determines your taxation rates, your popularity and legitimacy, and a wealth of other important features. Clearly, you're going to want to keep it as high as possible.
Stability can sink or rise on a scale of -3 all the way to +3, and the rule of thumb if higher being necessarily better definitely applies. To bolster your Stability rating, you're going to have to spend Religious Points via the game's Religion Menu, but you're also going to have to avoid antagonising both your citizens, and the surrounding nations.
With all of that in mind, you're going to have to balance between being a war-hawk and a lame duck when it comes to outward policy, as well as keeping a semblance of peace and tranquility within your borders. All we've got to add is - good luck.
