It is advisable to be somewhat careful with your conquering. After you conquer a province, you will want a large garrison there for about a full year, as peasants are naturally distrustful of a new Daimyo.

Insufficient garrison in a newly conquered province is the #1 reason for revolts. Plus, if one revolt happens, the next one will be even worse, and if a revolt SUCCEEDS then the damn thing's gonna snowball into neighboring provinces.. it can get messy, especially in the expansion.

All I can say is monitor your loyalty level in all your provinces. If it's below 100%, there is a chance of revolt. Be concerned if it's below 90%. Take decisive action if it's below 80%. Bust your a$$ is it's below 60%.

This is a critical factor in the game. Gothmog also listed some key factors in loyalty.
