The uprising in the occupied city! (Sid Meier's Civilization 6)

Good time of day. The problem is this:
Captured the city which is the capital, but did not want to become a part of my state. Every 5-6 turns, and it rises and a new grip, the uprising, and again so. What to do mind I will not put. In part 5 it was necessary to build the court, what is there to do?
Something simple for the stupid.In this series I play one week and only a couple of days in a 6 part began
Thank you!!!
