World War Ⅱ and Its Impact (1939–1960)

Module Introduction

As the Great Depression hit Europe, several new leaders rose to power under the new political ideologies of Fascism and Nazism. Mussolini in Italy and Hitler in Germany were both proponents of Fascism, using dictatorial rule to achieve national unity. Still, the United States remained focused on the economic challenges of its own Great Depression. It soon became clear, however, that Germany and Italy’s alliance was putting democratic countries at risk. Roosevelt first sought to support Great Britain and China by providing economic support without intervening directly. However, when Japan, an ally of Germany and Italy, attacked Pearl Harbor, catching the military base unaware and claiming thousands of lives, America’s feelings toward war shifted, and the country was quickly pulled into the global conflict.

The brunt of the war’s damage occurred far from United States soil, but Americans at home were still greatly affected by the war. Women struggled to care for children with scarce resources at their disposal and sometimes while working full time. Economically, the country surged forward, but strict rationing for the war effort meant that Americans still went without. New employment opportunities opened up for women and ethnic minorities, as white men enlisted or were drafted. These new opportunities were positive for those who benefited from them, but they also created new anxieties among white men about racial and gender equality. Race riots took place across the country, and Americans of Japanese ancestry were relocated to internment camps. Still, there was an overwhelming sense of patriotism in the country, which was reflected in the culture of the day.

Upon entering the war, President Roosevelt believed that the greatest threat to the long-term survival of democracy and freedom would be a German victory. Hence, he entered into an alliance with British prime minister Winston Churchill and Soviet premier Joseph Stalin to defeat the common enemy while also seeking to lay the foundation for a peaceful postwar world in which the United States would play a major and permanent role. With the aid of the British, the United States invaded North Africa and from there invaded Europe by way of Italy. However, the cross-channel invasion of Europe through France that Stalin had long called for did not come until 1944, by which time the Soviets had turned the tide of battle in eastern Europe. The liberation of Hitler’s concentration camps forced Allied nations to confront the grisly horrors that had been taking place as the war unfolded. The Big Three met for one last time in February 1945, at Yalta, where Churchill and Roosevelt agreed to several conditions that strengthened Stalin’s position. They planned to finalize their plans at a later conference, but Roosevelt died two months later.

Using the strategy of island hopping, the United States was able to get within striking distance of Japan. Only once they adopted this strategy were the Allied troops able to turn the tide against what had been a series of challenging Japanese victories. The war ended with Japan’s surrender. The combined Allied forces had successfully waged a crusade against Nazi Germany, Italy, and Japan. The United States, forced to abandon a policy of nonintervention outside the Western Hemisphere, had been able to mobilize itself and produce the weapons and the warriors necessary to defeat its enemies. Following World War Ⅱ, America would never again retreat from the global stage, and its early mastery of nuclear weapons would make it the dominant force in the postwar world.

Joy at the ending of World War Ⅱ was quickly replaced by fears of conflict with the Soviet Union. The Cold War heated up as both the United States and Soviet Union struggled for world dominance. Fearing Soviet expansion, the United States committed itself to assisting countries whose governments faced overthrow by Communist forces and gave billions of dollars to war-torn Europe to help it rebuild. While the United States achieved victory in its thwarting of Soviet attempts to cut Berlin off from the West, the nation was less successful in its attempts to prevent Communist expansion in Korea. The development of atomic weapons by the Soviet Union and the arrest of Soviet spies in the United States and Britain roused fears in the United States that Communist agents were seeking to destroy the nation from within. Loyalty board investigations and hearings before House and Senate committees attempted to root out Soviet sympathizers in the federal government and in other sectors of American society, including Hollywood and the military.

In 1953, Dwight D. Eisenhower became president of the United States. Fiscally conservative but ideologically moderate, he sought to balance the budget while building a strong system of national defense. This defense policy led to a greater emphasis on the possible use of nuclear weapons in any confrontation with the Soviet Union. Committed to maintaining peace, however, Eisenhower avoided engaging the United States in foreign conflicts; during his presidency, the economy boomed. Young Americans married in record numbers, moved to the growing suburbs, and gave birth to the largest generation to date in U.S. history. As middle-class adults, they conformed to the requirements of corporate jobs and suburban life, while their privileged children enjoyed a consumer culture tailored to their desires.

Young Americans in the postwar period had more disposable income and enjoyed greater material comfort than their forebears. These factors allowed them to devote more time and money to leisure activities and the consumption of popular culture. Rock and roll, which drew from African American roots in the blues, embraced themes popular among teenagers, such as young love and rebellion against authority. At the same time, traditional forms of entertainment, such as motion pictures, came under increasing competition from a relatively new technology, television.

After World War Ⅱ, African American efforts to secure greater civil rights increased across the United States. African American lawyers such as Thurgood Marshall championed cases intended to destroy the Jim Crow system of segregation that had dominated the American South since Reconstruction. The landmark Supreme Court case Brown v. Board of Education prohibited segregation in public schools, but not all school districts integrated willingly, and President Eisenhower had to use the military to desegregate Little Rock’s Central High School. The courts and the federal government did not assist African Americans in asserting their rights in other cases. In Montgomery, Alabama, it was the grassroots efforts of African American citizens who boycotted the city’s bus system that brought about change. Throughout the region, many white southerners made their opposition to these efforts known. Too often, this opposition manifested itself in violence and tragedy, as in the murder of Emmett Till.(2)
