History has proven that wars are either of political or of religious nature. Wars of religious nature push for a particular ideology, particularly that which is dictated by the constructs of their religion or god.

Religious wars include the Crusades in the Dark Ages and the Jihad. Political wars, on the other hand, are motivated by the need to control a particular government or group. It can be said that religious wars are also of political nature, as whoever it is who has control over religion ultimately has control over a majority.
