In my current game as France, the biggest problem has been keeping my large, well educated, very militant population happy.
I have found that the French are the hardest population to control, much more so than the British, Prussians, and Russians, who I also have much experience with. This is historical, as France changed government through revolutions several times during this period.
Though most of the game, I have met the consumer demand for food, in great variety, and consumer goods 100 percent, and have provided two thirds, sometimes more of the demand for luxuries. I have also enacted every possible social reform as soon as it is available.
Whenever there were signs of trouble, I rushed troops to the province with high police values, such as cavalry divisions and Gendarmes.
Nevertheless, militancy kept rising, and trouble developed in Meuse, where the contentment level somehow fell to one. For over four years Meuse has been mostly beset by strikes and riots, making it a negative, with no production and goods destroyed by riots. About two years, later, the same thing happened in Champagne. Nothing really helped.
Then a year before my current turn, strikes and riots appeared in two other provinces, where the contentment level was in the forties,but militancy was in the nineties. I realized I had to find something different, or I would lose the services of so many provinces that the nation might collapse.
I carefully examined the high militancy provinces where there were no riots or strikes, and found that each of these provinces had a garrison, in a fort, in the city.
In horror, I looked at the troops I sent to the troubled provinces, and they were all in the countryside. So enlightenment hit... Put them in the city itself!
After the first turn of doing this, contentment started to rise in the two newly troubled provinces, and rose into the eighties within a few turns. The riots and strikes lasted a few turns, then disappeared.
Alas, Meuse and Champagne were too far gone, and while contentment has risen from one to five or six, the riots and strikes have continued, mostly, though both provinces had a few turns of demonstrations, which are far less serious. Maybe they will get better in a few years, maybe not.
But now, in addition to everything else I was doing, I monitor the contentment level of my provinces. If it drops below seventy, I send in the gendarmes or cavalry, placing them right into the city. Within a turn or two, contentment is rising, and the danger of having more provinces ruined is gone.
I can hardly believe I made the mistake of putting the troops in the countryside, instead of the city, but I did. Now I know better.
Fascinating game!
