The Road to War mod in Civilization IV: Beyond the Sword involves playing as one of 11 or 16 civs (this number was increased in patch 3.19) in one of three scenarios. They are Europe 1936, Europe 1939, and Pacific 1936. There are three historical options. Accurate events take place at the exact time they happened in history. Random events happen within a few months of when they actually happened. In open play players can declare war whenever they see fit.
