Question concerning rebellions

Hello Medieval Total War fans, players! I'm very interested in this game, but have a few difficulties on my current campaign with Almohads, normal level, early age. I ask your help. Here are my questions: Why do sometimes the peasants revolt, even when the loyalty is 200% (taxes are set to automatic, because I've conquered nearly half of Europe and it takes a lot of time to adjust them manually)? How to avoid this? Does the presence of King's army in separate areas has an effect towards rebellions and unloyality? Thank you for your advices. Good luck!

If you have plenty of money, set taxes to low ,put spies in your territories&build borderforts to disable enemy spies.

You will keep the threat of rebellions since there's a (lame) mechanism in the game which increases the chance of it happening with every territory you capture...

Just make sure you have large centralised armies which can strike quickly...
