Mobilizing, equipping, recruiting, and training the military stretched over the nineteen months of America’s engagement in the war. Congress declared war on April 6, 1917, and enacted the draft for men one month later. Eventually over four million men and women served in the military during the conflict. Social welfare organizations also expanded to provide essential services.
