Long ago, Germany was split in two. 
There was a big wall in the city of Berlin. This wall kept the two sides apart. Many people wanted to be together again. They held protests to ask for change.
In 1989, the wall came down. This was a very big moment. Soon, the two lands became one country again. 
Now, Germany is one single nation. People celebrate this with a holiday every year. It is a time to remember unity.
After World War II, Germany was divided into parts. 
In 1949, two new countries formed. West Germany was a democracy. East Germany was a communist state. A wall was built in Berlin. It kept the two sides apart.
By 1989, things began to change. Many East Germans held protests. They wanted more freedom. This was called the Peaceful Revolution. In May 1989, a border fence in Hungary was removed. This let many people flee to the West. Then, the Berlin Wall fell on November 9, 1989.
Leaders worked on a Unification Treaty. On October 3, 1990, the two lands became one. 
German reunification was a major event in history. It was the process of making Germany one single country again.
The division worked by creating two different types of nations. In 1949, the American, British, and French zones joined together. They formed the Federal Republic of Germany, also known as West Germany. 
Change began to happen in 1989 through a movement called the Peaceful Revolution. This movement started when East German citizens held many protests. 

Leaders then worked hard to bring the two sides together. They held negotiations to create a Unification Treaty. 
This history helps us understand modern Europe. The reunification changed how many countries work together. For example, the new Germany kept its seats in NATO and the United Nations. 
German reunification was the historic process of re-establishing Germany as a single sovereign state. This process began on November 9, 1989, and reached its conclusion on October 3, 1990. During this time, the German Democratic Republic (GDR) was dissolved. Its constituent federated states were integrated into the Federal Republic of Germany (FRG). This integration created the modern German nation we recognize today. 
The roots of this division trace back to the end of World War II. After the unconditional surrender of German armed forces in 1945, the German Reich ceased to exist. There was no central government authority left in the country. The four Allied powers—the United States, the United Kingdom, France, and the Soviet Union—occupied Germany. 
Two distinct states emerged from these occupation zones in 1949. The American, British, and French zones combined to form the Federal Republic of Germany (FRG) on May 23, 1949. This state, often called West Germany, was a liberal democracy. In October 1949, the Soviet-occupied zone became the German Democratic Republic (GDR). This state, or East Germany, was a communist nation with a planned economy. The two countries lived side-by-side during the Cold War. Most borders between them were physically fortified and tightly controlled. West Germany joined NATO in 1955, while East Germany belonged to the Warsaw Pact.
Change began through a series of events known as the Peaceful Revolution. This movement included many protests by East German citizens. A major turning point occurred on May 2, 1989. On this date, Hungary removed its border fence with Austria. This created a hole in the Iron Curtain, which was the political boundary dividing East and West. 
Following the fall of the Wall, formal negotiations began to unite the two nations. The GDR held its first free elections on March 18, 1990. This led to the creation of a Unification Treaty between the two Germanies.
The legal structure of the new state is unique. The reunified Germany is not a successor state to the GDR. Instead, it is an enlarged continuation of the West German state. 

There has been much debate regarding the terminology used to describe these events. Some people call the process "German unity," which is the official term in the 1990 treaty. Others refer to it as "Die Wende," meaning "the turning point." Some scholars and political figures have even used the term "annexation" to describe the process. For example, in 2010, Matthias Platzeck referred to it as an "anschluss." However, others, including Mikhail Gorbachev, have rejected such labels. Regardless of the name, the events of 1989 and 1990 fundamentally reshaped the political landscape of Europe.
