The Developments of WWI refer to the significant political, military, social, and technological changes that occurred during the First World War from 1914 to 1918. This period saw the emergence of total warfare, where entire nations mobilized resources and populations for the war effort, resulting in unprecedented levels of destruction and loss of life. The conflict also led to major shifts in global power dynamics, technological innovations in warfare, and social changes that reshaped societies across Europe and beyond.
