After I conquer a province, I have to leave a lot of troops in that province for a while; OK but after some time, after the population gets used to the new ruler they should transfer to the new religion and let me move most of my troops out of the province. That doesn't happen some times (e.g. Portugal conquered with the Almohads) and I have to let in the province some 900-1100 soldiers. How do I get to convince the population to let me move my troops without getting a rebelion?
Thank you for your answers
