I have a thing with controversy. What is controversy? It was always 0 for me, then I suddenly realized it's 65 (after I have been a marshall). Can someone explain?
You gain controversy by:
Losing a vassal
Leaving soldiers behind
Joining in or starting arguments with other vassals
Betraying someone
As Marshall: Any loss, such as having a village raided, caravan destroyed, peasants attacked, a lord losing a battle, a castle captured, or town captured will add to controversy in often large measures. If you face war on multiple fronts or have a large kingdom to defend, you can expect to reach near 100 controversy very quickly. The only solution is to give up being marshall in that case.
The more controversy you have, the higher the chance the soldiers will desert you and lower the chance vassals will join you. High controversy will prevent your king or queen from awarding you a fief. Very high controversy for a marshall makes it likely that the marshall will be replaced.
Controversy can be lost over time or you can win against an enemy vassal to lower your controversy. Also ending arguments between your vassals lowers it as well.
