In Europa Universalis II, Events are changes in the game state that are made under the direction of special scripts that the game has. The scripting language includes the ability to pop up a dialog for the player's consideration, allowing multiple choices with different effects. For modders, event coding is the easiest and most accessible part of the game to modify. Many mods exist which add a variety of events to many countries which have few or no events in the vanilla version of the game.
