World War II Key Facts for SAT Prep: Essential Events and Figures to Know

Explore key World War II events and figures that are critical for SAT high school preparation.

World War II was a monumental global conflict that reshaped the political, social, and economic landscapes of the world. Spanning from 1939 to 1945, it involved over 30 countries and resulted in significant changes that are still felt today. For high school students preparing for the SAT, a thorough understanding of the pivotal events and influential figures of this era is essential. This comprehensive guide delves into the critical aspects of World War II, providing detailed insights to enhance your historical knowledge and exam readiness.

The Causes of World War II

Understanding the roots of World War II is crucial for grasping the complexities of the conflict. Several interrelated factors set the stage for this global war.

Treaty of Versailles and Economic Turmoil

The Treaty of Versailles, signed after World War I, imposed harsh penalties on Germany, including significant territorial losses, military restrictions, and hefty reparations payments. These terms led to severe economic hardship and national humiliation in Germany. The global economic downturn during the Great Depression further exacerbated these issues, causing widespread unemployment and poverty.

Rise of Totalitarian Regimes

The economic instability allowed totalitarian leaders to rise to power by promising revival and national greatness. In Germany, Adolf Hitler and the Nazi Party capitalized on public discontent, promoting ideologies of nationalism and racial superiority. Similarly, Benito Mussolini established a Fascist regime in Italy, and militarists gained control in Japan, seeking expansionist policies.

Failure of Appeasement and the League of Nations

The policy of appeasement adopted by Britain and France, notably at the Munich Conference in 1938, allowed Hitler to annex territories without facing military opposition. Additionally, the League of Nations proved ineffective in enforcing peace, lacking the authority and military power to prevent aggression.

These factors combined created a volatile environment ripe for conflict, demonstrating how political decisions and economic conditions can lead to war—a key concept for SAT history sections.

Major Theaters of War: Europe and the Pacific

World War II was fought across multiple continents, but two primary theaters defined the conflict: the European Theater and the Pacific Theater.

European Theater

In Europe, the war began with Germany's invasion of Poland on September 1, 1939. This act of aggression led Britain and France to declare war on Germany. Significant events in this theater include:

• Battle of Britain (1940): A crucial air campaign waged by the German Luftwaffe against the United Kingdom, aiming to achieve air superiority but ultimately failing due to British resilience and radar technology.
• Operation Barbarossa (1941): Germany's invasion of the Soviet Union, which opened the Eastern Front and led to some of the war's largest and deadliest battles.
• D-Day (June 6, 1944): The Allied invasion of Normandy marked a turning point, leading to the liberation of Western Europe from Nazi control.

Pacific Theater

The Pacific conflict primarily involved the United States and Japan. Key events include:

• Attack on Pearl Harbor (December 7, 1941): Japan's surprise attack on the U.S. naval base prompted America's entry into the war.
• Battle of Midway (June 1942): A decisive naval battle that shifted the balance in favor of the Allies.
• Island Hopping Campaign: The U.S. strategy of capturing strategic islands, moving closer to Japan's mainland.

Understanding these theaters is essential for appreciating the global scale of the war and the strategies employed by both the Allies and the Axis powers.

Key Figures of World War II

The war was shaped by influential leaders whose decisions had profound impacts on its course and outcome.

Allied Leaders

• Franklin D. Roosevelt (U.S.): The 32nd President who led the nation through the Great Depression and most of World War II, advocating for the "Arsenal of Democracy" and establishing the Lend-Lease program to support Allies.
• Winston Churchill (U.K.): The British Prime Minister known for his inspirational speeches and steadfast leadership, rallying the British people during the Blitz and maintaining opposition to Nazi Germany.
• Joseph Stalin (Soviet Union): The General Secretary who transformed the Soviet Union into a world superpower, his Red Army playing a crucial role in defeating Germany on the Eastern Front.

Axis Leaders

• Adolf Hitler (Germany): The Führer whose aggressive expansionism and genocidal policies led to the war and the Holocaust, promoting Aryan supremacy and anti-Semitism.
• Benito Mussolini (Italy): The Fascist leader who sought to recreate a Roman Empire, aligning with Germany but facing military defeats that led to his downfall.
• Hideki Tojo (Japan): The Prime Minister and military leader who advocated for Japanese expansion in Asia, orchestrating the attack on Pearl Harbor.

These leaders' ideologies, policies, and military strategies are critical for understanding the motivations behind the war's key events.

Significant Battles and Turning Points

Certain battles during World War II were pivotal in changing the war's direction.

Battle of Stalingrad (1942-1943)

This battle marked a turning point on the Eastern Front. The Soviet Union's successful defense of Stalingrad halted the German advance and began pushing German forces westward. The battle was characterized by brutal urban warfare and high casualties on both sides.

D-Day Invasion (June 6, 1944)

Known as Operation Overlord, the invasion involved over 156,000 Allied troops landing on the beaches of Normandy. This operation established a Western front against Germany, leading to the liberation of France and weakening German forces.

Battle of Midway (June 1942)

A critical naval battle in which the U.S. Navy, using intelligence breakthroughs, ambushed and sank four Japanese aircraft carriers. This victory halted Japanese expansion and shifted the momentum in the Pacific Theater.

Understanding these battles helps students grasp how strategic decisions and military tactics influenced the war's outcome—a vital component for SAT essay and multiple-choice questions.

The Holocaust and Human Rights Violations

The Holocaust was one of the most heinous atrocities in human history, orchestrated by Nazi Germany.

Systematic Genocide

• Persecution of Jews: Implemented through discriminatory laws, ghettos, and mass deportations.
• Concentration and Extermination Camps: Facilities like Auschwitz, Treblinka, and Sobibor where millions were murdered.
• Other Victims: Included Romani people, disabled individuals, political dissidents, homosexuals, and others.

International Response

• Nuremberg Trials: Post-war military tribunals held to prosecute Nazi war criminals for crimes against humanity.
• United Nations Universal Declaration of Human Rights (1948): Established to prevent future atrocities.

Studying the Holocaust is essential for understanding the consequences of unchecked hatred and the importance of human rights—a topic frequently explored in SAT critical reading and writing sections.

The Role of Technology and Intelligence

Technological advancements and intelligence operations significantly impacted the war's progression.

Technological Innovations

• Radar and Sonar: Improved detection of enemy aircraft and submarines, crucial for defensive strategies.
• The Atomic Bomb: Developed under the Manhattan Project, leading to the bombings of Hiroshima and Nagasaki in August 1945. This introduction of nuclear warfare had profound ethical and geopolitical implications.

Intelligence Efforts

• Codebreaking: The Allies' ability to decrypt Axis communications, such as Germany's Enigma code and Japan's Purple code, provided strategic advantages.
• Espionage: Use of spies and double agents to gather intelligence and mislead enemy forces.

Understanding these elements highlights the interplay between technology, intelligence, and warfare—an interdisciplinary topic relevant to SAT subject areas.

The Home Front: Civilians and the War Effort

The war had significant impacts on civilian life and societal structures.

Economic Mobilization

• War Production: Factories shifted from consumer goods to military equipment, boosting employment and ending the Great Depression in the U.S.
• Rationing: Governments controlled the distribution of scarce resources like food, fuel, and rubber.

Social Changes

• Women's Roles: Women entered the workforce in large numbers, exemplified by figures like Rosie the Riveter, leading to shifts in gender roles.
• Internment Camps: In the U.S., Executive Order 9066 led to the internment of Japanese Americans, raising questions about civil liberties.

These changes demonstrate how war can accelerate social transformation, a concept that can be analyzed in SAT essay prompts.

The Formation of the United Nations

In response to the failures of the League of Nations and the devastation of World War II, the United Nations was established.

Objectives

• Preventing Future Conflicts: Aimed to facilitate cooperation in international law, security, economic development, and human rights.
• Promoting Peace: Provided a platform for dialogue and conflict resolution.

Structure

• General Assembly: All member nations have equal representation.
• Security Council: Responsible for maintaining international peace, with five permanent members wielding veto power.

Understanding the UN's formation is critical for grasping post-war international relations—a topic often covered in SAT social studies passages.

The Aftermath and the Beginning of the Cold War

The end of World War II set the stage for new geopolitical tensions.

Division of Europe

• Iron Curtain: The ideological and physical boundary dividing Europe into two separate areas: the democratic West and the communist East.
• Marshall Plan (1948): The U.S. program providing aid to Western Europe to rebuild economies and prevent the spread of communism.

Nuclear Arms Race

• Soviet Atomic Bomb (1949): The USSR's successful test ended the U.S. monopoly on nuclear weapons, initiating an arms race.
• Containment Policy: The U.S. strategy to prevent the spread of communism worldwide.

These developments are essential for understanding the origins of the Cold War, a frequent topic in SAT history questions.
