[How to stop famous rebellions?]

• Keep the crown authority positive or at least at zero.
• Try to avoid opinion drops as negative opinions will lead to low stability.
• Try to keep wars short and effective. Long wars lead to war exhaustion which will reduce stability across your kingdom for a long time.
• Rapid expansion can lead to kingdom instability. Provinces that follow a different religion/culture or are loyal to other kingdoms will always be unhappy if you take over. Make sure to gain the foreign province's loyalty before you siege the city.
• Use Clerics' "Commit to Charity" skill to directly increase stability.
• Make sure to destroy the rebels as soon as the spawn. Leaving rebellions unhandled can lead to them becoming famous rebels that can even hold cities across several kingdoms.
• Certain Kingdom Traditions can increase stability.
