• Key Themes: This period saw rising Imperialism, the Spanish-American War, the flourishing of Progressivism, the complexities of World War I, the economic turmoil of the Great Depression, World War II, and significant changes in Postwar Diplomacy.

US Foreign Policy 1890–1945

  • The United States transitioned into a global power largely due to its industrial might, technological advancements, and military growth. By the end of the 19th century, American industries were producing goods at an unprecedented rate, which prompted the need for new markets.

  • Initial motivations for overseas involvement encompassed:

    • Economic Access: Seeking new markets for surplus goods and sources for raw materials.

    • Military Strategy: Establishing naval bases and coaling stations to extend influence and military presence.

    • Ideological Spread: Promoting American values and influence globally, often under the guise of benevolence and democracy.

    • Fear of Rivals: Competing against European powers for territory and influence heightened the urgency for expansion.

Imperialism Debates

  • There was a rising tension between imperialism and isolationism following President Washington's advice advocating for self-determination. The legacy of the Civil War, especially its aftermath, spurred debates on America’s proper role as a burgeoning power on the world stage, prompting varied opinions about expansionism and interventionism. Key figures expressed concerns about moral implications and the impact on national identity.

Spanish-American War (1898)

  • Causes: American intervention was spurred by several factors: strong interest in Cuban independence from Spain, the rise of jingoism (extreme patriotism), pervasive yellow journalism inflating public sentiment, and reports on Spanish atrocities, which molded public opinion against Spain.

  • Key Events:

    • The sinking of the USS Maine in Havana Harbor ignited a war hysteria.

    • The De Lome Letter, which criticized President McKinley, intensified calls for intervention.

    • Public pressure, fueled by sensationalist media, led Congress to authorize military action.

  • Outcomes: Following the war, the Treaty of Paris was signed, granting Cuba independence and ceding Puerto Rico, Guam, and the Philippines to the United States. This marked a significant expansion of American territories and influence, resulting in debates over the future governance of these territories.

Progressivism (1900-1920)

  • This reform movement sought to address political corruption, social injustices, and economic inequalities. Progressives aimed to harness government to improve society and initiated several key changes, culminating in four significant constitutional amendments:

    • The Sixteenth Amendment: Instituted a federal income tax.

    • The Seventeenth Amendment: Allowed for the direct election of Senators, empowering the electorate.

    • The Nineteenth Amendment: Granted women the right to vote, marking a significant victory for the women's suffrage movement.

    • The Eighteenth Amendment: Instituted prohibition, reflecting social concerns about alcohol consumption. This era also saw the rise of influential figures like Theodore Roosevelt and Woodrow Wilson championing progressive reforms.

WWI (1914-1918)

  • Initially, the US maintained a stance of neutrality, heavily influenced by strong economic ties with Allies and widespread Pacific isolationism. However, several provocations changed public sentiment:

    • The sinking of the Lusitania, killing American passengers, and unrestricted submarine warfare committed by Germany.

    • The Zimmerman Telegram, where Germany proposed a military alliance with Mexico against the US, galvanized American support for entering the conflict.

  • The US declared war in 1917, entering on the side of the Allies to protect democracy and ensure peace. The war effort saw significant mobilization of resources, women's participation in the workforce, and the establishment of government agencies for military production.

The Great Depression (1929)

  • The stock market crash triggered a decade of economic despair. Contributing factors included:

    • Overproduction in industries, leading to surplus.

    • High tariffs stifling international trade.

    • Uneven income distribution, where wealth was held by a small minority while many struggled.

  • Effects: Unemployment soared to unprecedented levels, leading to mass migration and the collapse of businesses across the nation. Societal despair was reflected in widespread protests, dust bowl conditions in the Midwest, and significant socio-political shifts seeking governmental intervention, culminating in Franklin D. Roosevelt's New Deal.

WWII (1939-1945)

  • The US entry into WWII was catalyzed by the surprise attack on Pearl Harbor in December 1941. The mobilization for war was extensive, with government taking a leading role in directing the economy and resources.

  • Key military strategies included:

    • Island Hopping in the Pacific: A strategy to capture strategically important islands while bypassing heavily fortified ones, enabling Allied progress towards the Japanese mainland.

    • Collaborative efforts in the European theater, where the D-Day invasion at Normandy constituted a pivotal moment in the Allied victory and subsequent defeat of Axis powers.

Postwar Diplomacy

  • The aftermath of WWII saw the formation of the United Nations, aimed at fostering international cooperation and preventing future conflicts. The rise of tensions with the Soviet Union led to the Cold War, characterized by ideological competition, the arms race, and proxy wars.

  • America transitioned from a policy of isolationism to one of global leadership, engaging in international politics and shaping global policies, notably in Europe and Asia, as it contested with the USSR’s contrasting ideologies.

Conclusion

  • The period from 1890 to 1945 marked a profound transformation in the identity of the United States, as it evolved from a regional power to a principal global player, navigating the complexities of imperialism, the impacts of war, and a redefined role in international diplomacy, which set the stage for future global relations.
