The Haber-Bosch process was developed largely because of Germany's need for explosives in World War I. Ammonia gas is converted to nitric acid, which, in turn, is used in making sodium and potassium nitrate, major components of explosives. Fritz Haber believed that it was his patriotic duty to contribute to the German war effort in whatever way he could, which led to his development of a new method for making ammonia.

  the Haber-Bosch Process was developed for explosives production during war, but is also in peaceful applications like agriculture/farming.
