When the United States entered World War II in 

1941

 , millions of men entered the military. This created a need for workers in many jobs, including those dealing with 

 . Millions of women stepped forward to fill these jobs. This may not seem like a major situation today, but back then factor work was not available to most women. They were expected to do things like 

 or not work at all. But during the war, it was extremely that they be put into more 

 -type work.
The U.S. government began an 

 campaign in 1942 to encourage 

 to hire women an to encourage women to apply for those jobs. They used the image of a woman in a blue work uniform rolling up her sleeves, and reminding women “We can do it!” Of course, “Rosie” was a 

 character, created specifically for this war effort. However, her impact was very real. Millions of women did enter the workforce, making planes, tanks, 

 , and many other things needed for the war effort. Thanks to them, the U.S. troops had enough weapons to defeat the 

 powers- Germany, Italy, and Japan- by mid-

1945
