I just lost a town to my neighbor Isabella. I am Willem. Because he is creative, I never though this would be an issue. It also happened to me in a previous with a non-creative leader. Without going to war, what can be done to to regain the town? I'm in Caste System right now, so I was thinking of trying to generate a Great Artist by using a few specialists. The city in question is a commerce city. This is probably a basic question, one I rarely concerned myself with in past.
