Joseph Stalin was the leader of the Soviet Union. Stalin and Hitler agreed not to attack each other. This allowed Hitler to attack other countries. Germany formed an alliance with Italy and Japan. These nations were called the Axis Powers.
4World War IIBritain and France formed an alliance called the Allied Powers or Allies. They tried to stop Germany by signing an agreement with Hitler. The Allies would allow Hitler to keep the land his armies had already taken if Hitler stopped attacking other countries.
5World War IIIn 1939, Hitler broke his promise. Germany attacked Poland. The Allies declared war on Germany. Then Italy and Japan declared war on the Allies. By the end of 1941, Germany controlled most of Europe.But, Germany did not control Britain. The Germans bombed Britain many times. U.S. President Franklin D.

6America Enters the WarJapan wanted to control other Asian countries. Japan invaded China and planned to invade other Asian nations too. But, the Japanese knew that the U.S. Navy could stop this plan. In 1941, the Japanese attacked the U.S. Navy at Pearl Harbor, Hawaii. Thousands of Americans died. The next day, Congress declared war on Japan. The United States joined the Allies and entered World War II.
7The Home FrontThe U.S. armed forces grew weaker in the 1920s and 1930s. The U.S. military was not ready for a war when Japan attacked Pearl Harbor in The United States needed to mobilize for war. Mobilize means to get ready to fight.The military needed soldiers. The soldiers needed guns, uniforms, airplanes, and tanks. More than 15 million Americans joined the armed forces, including 100,000 women. Some were drafted.
8The Home FrontThe government spent billions of dollars in supplies. It paid businesses to make the supplies. Factories hired millions of new workers. Many of them were African Americans and women. The nickname “Rosie the Riveter” was given to the many women who worked in jobs that only men had held before. Some factories stopped making consumer goods to make military supplies. U.S. factories made more war supplies that the other nations. American scientists made better helicopters and airplanes.
9At Home in WartimeThe military needed lots of food for the soldiers. Meat, sugar, and gasoline were rationed. Many families planted gardens to grow their own food. American culture changed. Many people knew someone fighting in the war.
10At Home in WartimeMany people were afraid Japanese Americans would help Japan during the war. The government forced over 100,000 Japanese Americans to move to internment camps, a place where prisoners are held during wartime. Most of these people were American citizens. Some Italian Americans and German Americans were sent to internment camps. Thousands of Japanese Americans fought for the United States.
11Winning the War Battles in North Africa and Europe German and Japanese victories surprised the Allies, but they fought back. The Allies defeated Germans and Italians in North Africa.

This mass murder is called the Holocaust.
14The Cold WarThe U.S. and the Soviet Union worked together to win World War II. Differences between the countries pushed them apart after the war.The countries had different ideas about economics and government. Americans live under capitalism. We have a market economy and a democratic government. A democratic government is where the people vote for their leaders.Soviets live under communism. Under communism, the government controls production of goods, and owns the nation’s natural and capital resources. Their leader was a dictator. Joseph Stalin was the Soviet Union’s dictator. His government arrested people who spoke out against communism.
15The Cold WarBy 1947, the Soviet Union and the United States were in a Cold War. This was a war of words and ideas. When World War II ended, the Allies shared control of Germany. The Soviet Union controlled the eastern half and the U.S., Britain, and France controlled the western half. The capital city was divided. The Soviets controlled East Berlin and the Allies controlled West Berlin.
16The Cold WarThe Soviet Union created communist governments in Eastern Europe. Winston Churchill, leader of Britain, said an “iron curtain” divided Europe. The curtain was not real. It was a symbol of differences between communist and non-communist countries.In 1949, the United States, Canada, Britain, and most of the non-communist European countries formed the North Atlantic Treaty Organization, or NATO. It wanted to keep the Soviets from forcing nations to be communist.
17Conflicts in Europe Grow Soviets blocked the roads and railroads to West Berlin in The U.S. and Britain broke this blockade. Airplanes took food and supplies to people trapped in West Berlin. This was called the Berlin Airlift.Many people from East Berlin escaped to West Berlin during the 1950s. In 1961, the Soviets began to build a wall. It divided East Berlin and West Berlin. It was called the Berlin Wall.
18Communism SpreadsAmericans worried that Soviets would spread communism everywhere. The Soviets helped a communist army in China. China became communist. Now two of the biggest nations in the world were communist.In 1949, the Soviet Union built an atomic bomb. U.S. leaders wanted their military to be stronger than the Soviets’. An arms race began. People worried that this race would lead to a nuclear war. Joseph McCarthy was an anti-communist who claimed that communists worked in the U.S. government.During the 1950s, anti-communism grew in the U.S. Some anti-communists believed communist spies were everywhere. Many government workers were fired. A few spies were found. But most people were innocent.
19Cold War ConflictsAfter World War II, the Allies formed the United Nations (UN). More than 50 countries joined the UN to try to keep peace in the world.In 1950, North Korea was communist. South Korea was not. North Korea invaded South Korea. The Soviets supported North Korea. The UN defended South Korea. The United States sent the most soldiers.
