World War I was considered the war to end all wars. The war brought technological advances on and off the battlefield and produced weapons that were deadlier than ever before. Developments in engineering, chemistry, and metalworking created unmerciful conditions and saw a transition from animal power to machine power as the primary means of victory. The techniques and knowledge in the field of medicine improved and adapted to the mass destruction of war. Outside the war zone, the home front proved to be a vital artery in the war effort through its sacrifices and undying support of patriotism. In all, the war became an unprecedented catastrophe that affected people around the globe and shaped the modern world.
This is a recurring event.
