The Great War
The First World War started in the summer of 1914 because of a single, violent event in a small corner of Europe. A young man killed a prince named Archduke Franz Ferdinand, who was supposed to be the next leader of the Austro-Hungarian Empire. While this might have stayed a local problem, Europe at the time was full of secret “friendship deals” called alliances. These deals meant that if one country got into a fight, its friends had to jump in to help. Because of these promises, a small argument between two countries quickly pulled in all the world’s biggest powers, including Great Britain, France, Russia, and Germany. Everyone thought the fighting would be over in just a few months, with soldiers home by Christmas, but they were tragically wrong.
Instead of a quick victory, the war turned into a giant, muddy stalemate. On the Western Front in France and Belgium, both sides dug thousands of miles of deep ditches called trenches. Soldiers lived in these cold, wet holes for years, facing off against the enemy across a patch of destroyed land filled with barbed wire. It was a terrifying time because new inventions like tanks, airplanes, and poison gas were being used for the first time. These weapons were much more powerful than the old-fashioned ways of fighting, which led to a massive loss of life without either side moving very far. For three long years, the war stayed stuck in the mud, and millions of people suffered while the world’s resources were used up.
The year 1917 changed everything. In the East, Russia was so exhausted and hungry that its people started a revolution and quit the war entirely. This gave Germany a chance to move all its soldiers to the West for one last big attack. However, at almost the same time, the United States decided to join the fight on the side of Britain and France. Germany had been using submarines to sink American ships, which finally pushed the U.S. to send millions of fresh soldiers and huge amounts of food and supplies. This gave the tired Allied armies the energy they needed to finally push the German army back toward its own borders.
By late 1918, Germany and its partners were completely worn out. Their people were starving at home, and their soldiers were tired of fighting a war they couldn’t win. On November 11, 1918, both sides agreed to stop the shooting. A few months later, they signed a peace treaty that blamed Germany for everything and made them pay a lot of money. While the “Great War” was finally over, it left the world in a very messy state. New countries were created and old empires disappeared, but the harsh feelings from the peace deal meant that true peace wouldn’t last forever. It was a war that changed how people saw the world, leaving behind a sadness that would eventually lead to another big fight twenty years later.
World War II
World War II began in 1939 because the peace from the first war didn’t last as long as everyone hoped. After the first war, Germany was left poor and angry, which allowed a leader named Adolf Hitler and his Nazi party to take power by promising to make the country strong again. Hitler started breaking international rules by building a massive army and taking over neighboring lands. For a while, other countries like Britain and France tried to keep the peace by letting him have small pieces of land, hoping he would eventually stop. This was called “appeasement,” but it didn’t work. When Hitler’s tanks rolled into Poland on September 1, 1939, Britain and France realized they had to fight back, and the biggest war in history officially began.
In the first few years, it looked like Germany and its partners, Italy and Japan (called the Axis Powers), might actually win. Germany used a terrifyingly fast way of fighting called “Blitzkrieg,” or lightning war, using planes and tanks to overwhelm countries in just weeks. They quickly conquered France and began bombing London every night. Meanwhile, on the other side of the world, Japan was busy taking over islands and countries in Asia to get more resources. Everything changed in 1941 when two massive events happened. First, Hitler made the huge mistake of attacking the Soviet Union, which pulled a massive Russian army into the fight. Second, Japan launched a surprise attack on a U.S. Navy base at Pearl Harbor in Hawaii. This brought the United States, with all its factories and fresh soldiers, into the war to help Britain and the Soviet Union (the Allied Powers).
The middle years of the war were a giant, violent tug-of-war. The Allies began to push back in three main areas. In the freezing winters of Russia, the Soviet army finally stopped the Germans at the Battle of Stalingrad. In the Pacific Ocean, the U.S. Navy won a huge battle at Midway, stopping Japan’s progress. Then, in the summer of 1944, the Allies pulled off the biggest invasion in history, known as D-Day, landing thousands of ships on the beaches of France to start driving the German army back home. As the Allied soldiers moved toward Germany, they discovered the terrible secret of the Holocaust, where the Nazis had built camps to murder millions of innocent people, mostly Jews. This discovery showed the world just how evil the regime they were fighting truly was.
By 1945, the Axis Powers were trapped and defeated. Hitler took his own life in an underground bunker as the Soviet and American armies met in the middle of Germany, and the fighting in Europe ended in May. However, the war in the Pacific against Japan continued for a few more months. To end the war quickly and avoid losing millions more soldiers in a ground invasion, the United States used a new and terrifying weapon: the Atomic Bomb. They dropped two of these bombs on the Japanese cities of Hiroshima and Nagasaki. The destruction was so massive that Japan surrendered in August 1945. The world was finally at peace, but it was a different world than before. The United Nations was created to help countries talk out their problems instead of fighting, but a new kind of “cold” tension was already starting between the two biggest winners, the U.S. and the Soviet Union.
Cold War
The Cold War began almost immediately after the celebration of the Second World War ended in 1945. Even though the United States and the Soviet Union had been partners against Hitler, they didn’t actually like or trust each other. They had completely different ideas about how a country should be run. The United States believed in “Capitalism,” where people could own their own businesses and vote for their leaders. The Soviet Union believed in “Communism,” where the government owned everything and controlled every part of life. Because both sides now had powerful nuclear weapons, they knew that a real “hot” war with bullets and bombs would likely end the world. Instead, they entered a forty-year “staring contest” where they competed to see who was stronger without ever actually shooting at one another directly.
Europe was quickly split in two by what people called the “Iron Curtain.” The Soviet Union took control of the countries in the East, while the U.S. and its friends stayed in the West. The city of Berlin in Germany became the most famous symbol of this divide when the Soviets built a massive concrete wall right through the middle of it to stop people from escaping to the West. While they weren’t fighting with guns, the two sides fought in other ways. They had a “Space Race” to see who could get to the moon first, and they used thousands of secret spies to steal each other’s technology. They also got involved in “proxy wars” in places like Korea and Vietnam, where they supported opposite sides in local fights just to make sure the other superpower didn’t gain too much influence.
The scariest moment of the entire Cold War happened in 1962 during the Cuban Missile Crisis. The Soviet Union put nuclear missiles on the island of Cuba, which was very close to the United States. For thirteen days, the whole world waited in fear, thinking a nuclear war was about to start. Luckily, the leaders of both countries realized how dangerous the situation was and talked it out. The Soviets agreed to take the missiles away, and the U.S. promised not to invade Cuba. This event showed everyone just how close they were to disaster, and for a while afterward, both sides tried to be a little bit more careful with how they treated each other.
By the 1980s, the Soviet Union was starting to run into big trouble. Their government was spending too much money on weapons and not enough on food or clothes for its people. A new leader named Mikhail Gorbachev tried to fix the system by giving people more freedom to speak their minds and own small businesses. However, once the people got a little bit of freedom, they wanted it all. In 1989, the famous Berlin Wall was torn down by happy crowds, and the Soviet government didn’t try to stop them. By 1991, the Soviet Union officially broke apart into fifteen different countries, and the Cold War finally came to an end. It was a long era of fear and tension that shaped the modern world, leading to many of the technologies and alliances we still see today.
