Technology during World War I
Technology during World War I (1914–1918) reflected a trend toward industrialism and the application of mass-production methods to weapons and to the technology of warfare in general. This trend began at least fifty years prior to World War I during the American Civil War of 1861–1865; this continued through many smaller conflicts in which soldiers and strategists tested new weapons.
