I think it's from revolting, but maybe to monarchy? To get some AI to know Poly in time is easy in this game. To get anybody research CoL would have been quite a risk...What I find more intriguing is pondering the reason for Ivan's drop in culture rate between turns 40 and 50
Possible reasons could include revolt (? philo -> trade for either poly or CoL and free govt tech) or less likely either losing capital or shifting capital (not suggested by their territory graph). If we make a successful sling shot we should revolt in the following 10 turns which Klarius hasn't, so perhaps they missed / didn't attempt slingshot.

It was rather to road that tile, not connect the horses. I wanted a connection of our towns in the east - But it might not be the most pressing task maybe...Havnt looked at save yet, but from your pics I wonder at the plan to road the horses near GG. How do you plan to get them in our cultural control?
