Think about this question and I bet you can come up with the answer. There is a huge war effort in motion. A draft was instituted to get men into the armed services, and many men volunteered for duty as well. By the end of World War I, around 2 million men had volunteered for service and nearly 3 million more had been drafted into service. With all those men being deployed into military roles, who would be left to fill the need for civilian workers? Can you guess it? That's right, the demand for workers was filled by women.
The wartime efforts of women in the United States contribute much to the movement for advancing women's rights and opportunities in this country. In 1920 (not long after World War 1 ended), for the first time in US history, women were given the right to vote in national elections.
