Theory of War
The Theory of War is an ideology of what is acceptable in the context of war which covers aspects of war including reasonable cause, treatment of prisoners, what kind of tactics are aloud, and so. All of these are split in to two different categories; with one being the right to go to war, and the conduct of war. Many influences of the Theory of War include many Christian ideals which can reflect religions impact on the world.
Some of the first known ideas that relate to the Theory of War date back to 400 BCE with the Mahabrarata, an Indian epic which doesn't directly establish war theory but lays down some of the principles of war theory in concern with how war should be conducted. In the epic there is a talk amongst a bunch of brothers who contemplate if war is ever justified.

In book 3 of De jure belli ac pacis libri tres, Grotii insists that everyone involved are forced to act according to the conduct of war even if the cause of the war is justified or not. This show restraint and maybe a bit of sophistication by both sides in a situation that my not deserve such an agreement.
We can use history and take a look at it through the Theory of War to see if some of the wars were really all that just not only in the aspects of how they started, but also with how all sides conducted themselves during the war. The main cause for World War 1 starting was that Serbia wanted freedom from the Austria-Hungary Empire so a Yugoslav nationalist assassinated the heir to Austria-Hungary; resulting in Austria Hungary attacking Serbia, which crossed with a whole...
