Reality and illusion, 1945–1980 – Truman and Post-war America, 1945–1952:…

The idea

In 1945, the US emerged from the Second World War as a superpower, shaped by the conflict's legacies. The presidency, strengthened by Roosevelt, wielded unprecedented executive power. The political landscape featured a fragile Democratic coalition of Southern conservatives and Northern liberals, opposing Republicans who championed limited government. Post-war prosperity was fuelled by wartime savings and the GI Bill, creating an affluent society. However, this wealth highlighted regional, ethnic, and social divisions. The South remained segregated under Jim Crow laws, while the North faced racial tensions. Socially, women faced pressure to return to domestic roles, and ethnic minorities experienced discrimination despite wartime service.

What earns the marks

• Evaluate the extent to which the Second World War expanded the powers of the presidency.
• Analyse the ideological differences and internal divisions within the Democratic and Republican parties in 1945.
• Assess the economic factors that contributed to post-war prosperity, such as the GI Bill and accumulated wartime savings.
• Examine the regional disparities between the segregated South and the industrial North.
• Discuss the social and ethnic divisions, including the experiences of African Americans, women, and other minority groups post-1945.

Common mistakes and how to put them right

• Assuming the Democratic Party was uniformly liberal.

  Put it right: Recognise the deep divide between Northern liberals and Southern 'Dixiecrat' conservatives.

• Overstating the universality of post-war prosperity.

  Put it right: Acknowledge that economic benefits were unevenly distributed, often excluding ethnic minorities and rural populations.

• Believing the presidency had unlimited power.

  Put it right: Understand that while executive power grew during the war, it remained constrained by Congress and the Supreme Court.

Exam tips

• Use the GI Bill as a concrete example of how government policy stimulated post-war prosperity and social mobility.
• When discussing political parties, always highlight the fragility of the New Deal coalition to explain future political shifts.
• Contrast the de jure segregation of the South with the de facto segregation of the North to provide a nuanced view of regional divisions.
