During the first world war technology became very important. The machine gun was one of the main technologies uses during the war. Machine guns and artillery like large mounted guns that hurled explosive shells, fired more accurately and more rapidly than earlier weapons. Steamships and railroads could speed the moment of troops and supplies.

Poison gas was used by both sides which sometimes resulted in devastating results during the War. The Germans pioneered the large-scale use of chemical weapons with a gas attack on Russian positions on January 31, 1915. The first successful use of chemical weapons occured in 1915, near Ypres, when the Germans sprayed chlorine gas from large cylinders towards trenches held by French colonial troops. Before long, the Allies were using poison gas also. Over the course of the war both sides resorted to increasingly insidious compounds to beat gas masks, which were another new invention.
