World War II

Grade 8 · History · Free lesson

Hi there! I'm Studyfin, and today we will explore how World War II started, how it was fought on multiple fronts, and its major global impacts.

World War II began because of aggressive actions by dictators in Germany, Italy, and Japan. The United States entered the war in December 1941 after Japan launched a surprise attack on the U.S. naval base at Pearl Harbor in Hawaii.

The United States had to fight a war on multiple fronts, which means fighting in different parts of the world at the same time. American troops fought the Axis powers in Europe and also battled Japanese forces across the Pacific Ocean.

During the war, we also saw terrible human rights tragedies. The Holocaust was the systematic murder of six million Jews and millions of others by the Nazi regime, while in the U.S., fear led to the unfair internment of over 120,000 Japanese Americans in relocation camps.

✏️ Worked example

Explain how the concept of 'fighting on multiple fronts' applied to the United States during World War II, using the Pacific and European theaters as your evidence.

  1. Identify the definition of 'fighting on multiple fronts.' This means a nation must split its military forces, resources, and attention to fight enemies in completely different geographic regions at the same time.
  2. Locate the first front. In the European theater, the United States sent troops, planes, and ships across the Atlantic Ocean to fight Germany and Italy in Europe and North Africa.
  3. Locate the second front. In the Pacific theater, the United States sent forces across the Pacific Ocean to fight the expansion of the Japanese Empire.
  4. Analyze the challenges of this strategy. The U.S. had to produce massive amounts of supplies, build two separate navies, and manage supply lines that stretched across two different oceans.
  5. Conclude with a clear explanation. By dividing its forces between Europe and the Pacific, the United States successfully fought on multiple fronts to defeat the Axis powers simultaneously.
