在游玩游戏的全过程中经常会发生事件。事件可以对一个国家造成正面的、负面的或者是双重的效果。它们会以弹出窗口的形式出现在屏幕上，可能会允许玩家在多个选项之间进行选择，或者只是提醒玩家本事件已经发生，并让他们知道其结果。If the player has not chosen an option after four months on the same date, the first choice gets autoselected.
Triggered-only events are events that occur as a result of a character's actions. The events can happen to that same nation or to another nation altogether. The needed trigger can be as simple as one character choosing a particular option in an event or complex as taking over a certain county, thereby enabling an event at another character. The events are usually fired immediately or within a short amount of time from being triggered.
Pulse events
Pulse events are random events that happen within regular intervals of time. One of their main purposes is to provide interactions and a sense of randomness within the game. That being said, while the events are to happen they are still based on player's actions and the general state of the world; for example, for an religious event to fire, the player needs to have the required religion.
The events are grouped together into different sets depending on their purpose (regular gameplay or mechanic related) and assigned weights within their respective sets. Each set is programmed to fire in regular time intervals. The time intervals range from yearly intervals and up-to 5 year intervals. It is important to note however that there are several same-year intervals and it does not mean they'll fire at the same date. When the interval arrives an event is picked at random from within the set and fired. Events with higher weights have higher chances to fire than the lower ones. Having certain modifiers, lifestyle, counties etc. can increase or decrease some events' weights. Most pulses also have a weight for getting no event at all.
