Final answer:
Major conflicts such as WWI and WWII brought forth liberal and progressive ideas, leading to new opportunities and societal changes for groups like women and African Americans. These changes impacted the social and political landscape significantly, with the influence of war experiences on society continuing long after the conflicts ended.
Step-by-step explanation:
The question relates to the significant social and political changes that occurred during and after major conflicts, particularly World War I and World War II. The war served as a catalyst for exposure to more liberal and progressive ideas, leading to changes in the status quo. During this period, there was an expansion of opportunities for various groups, including organized labor, women, and African Americans. The new opportunities born from war included women working outside the home for the first time, African American men being eligible for jobs previously reserved for White men, and African American women finding employment beyond domestic services.
After the war, these newfound freedoms and roles challenged the prewar norms. Societal shifts, the New Left, and feminist movements exemplified the continued impact of these wartime experiences. The intersection of war, social change, and political movements underscored how deeply wartime experiences could reshape societal views.
