Final answer:
World War I transformed the relationships between governments and their citizens, as the war helped expand the influence of public opinion and drove significant societal changes, such as women's suffrage and increased control of industrial output through legislation.
Step-by-step explanation:
World War I significantly altered the relationship between the government and citizens as nations demanded a total war effort from their populations. The war provided unique opportunities for societal groups, such as women and African Americans, who filled essential roles in the workforce previously dominated by white men. This participation helped push the suffrage movement and opened discussions about civil rights. Public opinion became more influential, as journalism spurred patriotic fervor that impacted both the war's inception and the trajectory of the home front. Governments ramped up control over industrial output and public sentiment through new legislation to manage the war's demands, while at the same time, more democratic structures ensured citizens' voices were considered.
The war's aftermath was characterized by exhaustion and division among Americans, with returning soldiers facing trauma and Americans at home debating the United States' role in international affairs. Societal trends developed as many yearned for a return to 'normalcy,' signaling a conflict between societal progression made during the war and traditional values. In essence, World War I did not resolve international tensions; rather, it created new societal dynamics and exposed the devastating power of modern warfare.
