During both World Wars, women's roles in the workforce significantly expanded as they filled jobs traditionally held by men. With many men enlisted in military service, women took on roles in factories, agriculture, and other essential sectors, contributing to war efforts. In World War I, women worked in munitions factories, while in World War II, they became part of the workforce in greater numbers, often symbolized by "Rosie the Riveter." This shift not only demonstrated women's capabilities beyond domestic spheres but also laid the groundwork for future advancements in gender equality, as the wars challenged traditional gender norms and expectations.
