Korean War

The Korean War (25 June 1950 – 27 July 1953) was a big fight on the Korean Peninsula. North Korea and South Korea were the main sides. North Korea had help from China and the Soviet Union. South Korea was helped by the United Nations, mostly the United States. This war happened during the Cold War, a time when countries did not fight each other directly but supported other nations instead.

After World War II ended in 1945, Korea was divided into two parts along the 38th parallel. In 1948, each part formed its own government, and problems between them grew. On 25 June 1950, North Korea invaded South Korea, which started the war. The United Nations decided to help South Korea, and many countries sent soldiers to support them.

There were many big battles and the control of land changed often during the war. The war did not end with a peace treaty but with an armistice in 1953. This created a Demilitarized Zone (DMZ) between the two countries. Even today, North and South Korea are separate, and the world watches closely to help keep the peace.

Names

In South Korea, the war is often called the "625 War" because it began on June 25. In North Korea, it is known as the "Fatherland Liberation War." In the United States, it was sometimes called a "police action" because the country never officially declared war.

People in many English-speaking countries called it "The Forgotten War" because it did not get as much attention as World War II or the Vietnam War.

In China, the part of the war after their troops got involved is called the "War to Resist America and Assist Korea," while the part before that is called the "Korean Civil War." The term "Chosŏn War" is also sometimes used.

Background

Japanese colonization (1910–1945)

Main article: Korea under Japanese rule

Korea was ruled by the Empire of Japan from 1910 to 1945. Japan took control after winning wars against China and Imperial Russia. Many Korean nationalists left during this time. After World War II ended in 1945, Japan gave up control of Korea.

Division of Korea (1945)

Main article: Division of Korea

When World War II ended, Korea was split into two parts along the 38th Parallel — a line chosen by American officers. The Soviet Union controlled the area north of the line, and the United States controlled the area south of it. This split led to the creation of two separate governments: North Korea in 1948 and South Korea later that same year.

Joint US-Soviet occupation (1945–1948)

From 1945 to 1948, both the United States and the Soviet Union occupied different parts of Korea. Efforts to create one government failed, leading to separate elections. South Korea became a nation in 1948, and North Korea also became a separate nation that same year.

Chinese Civil War (1945–1949)

After Japan’s defeat, the Chinese Civil War resumed between the Communists and Nationalists. North Korea supported the Communists, giving them supplies and safe areas. Many Korean veterans who fought for the Chinese Communists later joined North Korea’s military.

Communist insurgency in South Korea (1948–1950)

Between 1948 and 1950, North Korea supported groups fighting against the South Korean government. These groups were often hidden in mountains and border areas. The South Korean military worked to stop them with help from American advisors.

Prelude to war (1950)

By 1949, North Korean leader Kim Il Sung thought it was time to invade South Korea. He asked for support from the Soviet Union and China. After getting their approval, he prepared his forces for an attack. The invasion was planned for June 1950, aiming to quickly capture South Korea’s capital, Seoul.

Comparison of forces

By mid-1950, North Korea had built a strong military with help from the Soviet Union and China. They had around 150,000 to 200,000 troops, tanks, aircraft, and artillery. South Korea had fewer soldiers, no tanks, and only a small air force. Even though South Korea had more people, its military was not well-equipped to defend against the attack.

Course of the war

The Korean War lasted from 1950 to 1953. It was a big fight between North Korea and South Korea. North Korea had help from China and the Soviet Union. South Korea had help from the United Nations, led by the United States.

The war started when North Korean soldiers crossed into South Korea. They wanted to bring both parts of Korea together under one government. South Korea and its allies stopped them.

There were many battles and changes in who controlled the land. After a while, the fighting stopped moving much, and both sides began talking about how to end the war. The war ended with an agreement to stop fighting in 1953, but no official peace treaty was ever signed. Because of this, North and South Korea are still considered to be in a state of war, even today. The line that separates the two countries along the 38th parallel is still there.

Characteristics

The Korean War had fighting on the ground and in the air.

On the ground, North Korea invaded South Korea. The United Nations sent troops to help South Korea. There were also special battles inside tunnels.

In the air, new jet airplanes fought for the first time. The United States used its power to try to stop North Korea from attacking.

North Korean soldiers used tanks from the Soviet Union. These tanks were strong at first. But the United Nations brought stronger weapons. A big landing at Incheon stopped North Korean supplies. This made North Korean soldiers leave and drop many tanks and guns.

The United Nations bombed North Korea a lot from the air. This bombing destroyed many buildings. The war also used helicopters for the first time to help injured soldiers. This helped more soldiers stay alive.

Casualties

The Korean War was a very serious conflict. Many people lost their lives, and many cities were destroyed. The war was very hard on everyone involved, and many lives were changed forever.

South Korea and the United Nations forces, led by the United States, faced difficult battles during this time.

Violations of the laws of war

The Korean War had many sad events where the rules of war were broken. Many people, including women, children, and older people, were hurt during these times.

One sad event was called the No Gun Ri massacre. In 1950, many people were killed by U.S. forces. Later, checks by U.S. and South Korean groups showed that these events did happen.

Aftermath

The Korean War changed both Koreas and the world. In North Korea, the war damaged factories and buildings. After the war, North Korea got help from the Soviet Union and China. It stayed under strict control and built a strong military.

South Korea was also damaged, but later grew strong with help from the United States and other allies. Today, South Korea is a democratic country with a powerful economy. American troops are still there, helping keep peace.

The war also affected the United States, leading to more military spending and many foreign military bases. For China, the war showed its strength to other communist countries, though it also made China rely more on the Soviet Union for a time.
