How did technological and industrial development revolutionize World War One? The tank, gas, flame throwers, submarines, barbed wire, flying Zeppelins were like nothing that had been experienced before. For this reason, World War I is the first global conflict that is globally acknowledged as a form of 'total war' - one in which everyone’s a target, any weapon is permitted, and the scope of the battlefield is unlimited. We’ll see a lot of historical firsts in WWI in terms of conducting war from the amount of devastation to the types of military technology used. And when a country is at total war, its economy must shift towards heavily focusing on the production of weapons, ammunition, and aid packages alongside more supplies that’ll aid troops abroad. To encourage intense and fervent nationalism while avoiding opposition that could hinder war efforts, governments resort to political propaganda, any art or media that promotes local support against a cause or enemy being degraded in such works. All of these elements are how WWI was waged and how millions of souls will be lost and changed forever.
