War aims of the First World War

The war aims of the First World War were formulated after the conflict began, reflecting the territorial, political, and economic objectives pursued by the belligerent states. Governments and public opinion often did not distinguish between war aims, causes of war, and the origins of the conflict. While some war aims, whether publicly declared or kept confidential, included extensive demands such as territorial annexations, these objectives alone do not fully explain the decision to enter the war. In certain cases, however, war aims and the casus belli overlapped, as seen with countries such as Italy, Romania, and Bulgaria.

During the First World War, additional war aims developed for the conflict, extending beyond the original casus belli. According to Professor Ernst Rudolf Huber, from the perspective of annexationist objectives, neither side can be accused of having entered the war to conduct a war of conquest. During and after the conflict, war aims and the question of responsibility were often seen as closely connected, although this association was largely superficial. War aims were also employed as instruments of warfare, particularly by the Western Allies.
