Long ago, many nations joined together. 

They met to talk about problems. They wanted to stop wars from starting. They also helped with health and work.
Some big nations helped the group. But some big nations did not join. This made it hard to keep peace.
Later, a new group was made. It is called the United Nations. This new group took over the old work. 
The League helped us learn to work together.
The League of Nations was a group of many countries. 

Leaders wanted to stop wars from starting. They used talk and rules to settle fights. The League also looked at many other things. It helped with global health and worker rights. It even worked to stop child labor. 
But the League had some big problems. It did not have its own army. It had to ask other nations for help. Many powerful nations did not join. The United States never joined the group. This made the League less strong. Some countries even left the League in the 1930s.
Because of these issues, the League could not stop the Second World War. It stopped working in 1946. A new group called the United Nations was made to take its place. 
The League of Nations was a very important group of countries. 

To make peace, the League used a plan called a Covenant. This plan had several main goals for all the member nations. One goal was to use collective security to prevent wars. This means countries would work together to stop any one nation from being aggressive. They also wanted to reduce the number of weapons in the world. This process is called disarmament. The League also helped settle arguments through negotiation and arbitration. 
History shows that many people worked hard to create this group. After the First World War ended, leaders met at the Paris Peace Conference. They signed the Covenant as part of the Treaty of Versailles on June 28, 1919. The League officially began its work on January 10, 1920. U.S. President Woodrow Wilson was a leading architect of the League. He even won the Nobel Peace Prize for his work on it. However, his own country, the United States, never actually joined the group. 
The League faced many hard jobs during its 26 years of work. It did not have its own army to enforce its rules. It had to rely on powerful countries like Britain, France, Italy, and Japan. At its largest, the League had 58 member nations. 

Even though it did not stop every war, the League did many good things. It helped improve working conditions and fought against child labor. 

The League of Nations was the first worldwide intergovernmental organization. Its primary mission was to maintain global peace. It was created to prevent the kind of massive conflict seen in the First World War. This organization represented a major shift in international diplomacy. For a century, nations had mostly acted on their own. The League tried to create a system where countries worked together. 
The League operated based on a document called the Covenant. This document outlined specific methods for keeping order. One method was collective security. This meant members would act together to stop any aggressive nation. Another goal was disarmament, which is the reduction of weapons. The League also used negotiation and arbitration to settle disputes. Arbitration is when an outside group helps decide a disagreement. 
The organization had several different parts to manage its work. The Assembly was one major body where members met. The Council was another body that handled important decisions. The League also managed many specialized committees. These committees focused on specific global issues. They worked on things like global health and labor conditions. They also looked at the rights of minorities in Europe. 
Many people helped design the League before it officially started. The Paris Peace Conference ended the First World War. This conference led to the signing of the Treaty of Versailles on June 28, 1919. The Covenant was actually Part I of that treaty. The League officially began its operations on January 10, 1920. U.S. President Woodrow Wilson was a leading architect of the plan. He even won the Nobel Peace Prize for his role. 
Despite its goals, the League faced serious challenges. It did not have its own standing army. It had to rely on powerful nations to enforce its rules. These nations were Britain, France, Italy, and Japan. If the League issued sanctions, it relied on these powers to comply. However, many great powers were often reluctant to act. This lack of enforcement weakened the League's credibility. 
Over time, the League's membership and strength changed. At its largest, between 1934 and 1935, it had 58 members. The United States never joined the organization. This was a major blow to its influence. Other countries also left during the 1930s. Japan and Germany left in 1933. Italy left in 1937, and Spain left in 1939. The Soviet Union was expelled in 1939. 
The onset of the Second World War showed the League's limitations. It could not prevent the aggression of the Axis powers. The organization became largely inactive as the war continued. It lasted for 26 years before it was dissolved. On April 18, 1946, the League officially ended its operations. Many of its parts were moved into a new group. This new group was the United Nations. 
Even with its failures, the League left a lasting legacy. It helped build the foundations for the rule of law. It strengthened the concept of collective security for future groups. The League also helped raise awareness for many human issues. These included child labor, slavery, and refugee crises.
