In Europa Universalis II, Revolt risk is the chance that a city will have a rebellion each time it faces a rebellion check. Revolt risk is often abbreviated RR. Revolt risk is commonly used to label two different (though closely related) things. One is the net revolt risk for a city, as in, "The RR in Thrace was 20%!". The other is the specific revolt risk addition or subtraction caused by some specific cause (see below): "The event gave me +24 RR for 10 years!" This article refers to individual causes of revolt risk as "revolt risk"; we use "net revolt risk" for the per-city sum of individual RR factors.
