East Berlin was a big city. 

Long ago, a big city was split in two. 
A tall wall kept the two sides apart. 
In the 1970s, people worked fewer hours. Their pay also went up.
Later, the wall came down. East and West Berlin became one city again. It was a very big change for everyone. 
After World War II, the city of Berlin was split into parts. 
In 1961, the government built the Berlin Wall. This wall kept East Berlin and West Berlin apart. 
Life in East Berlin changed over time. In the 1970s, workers earned more pay. They also worked fewer hours. The city had many different areas called boroughs. 
On October 3, 1990, the two sides became one again. This was the day Germany was reunified. East and West Berlin joined to become one city. The government spent much money to fix the city. They wanted to make the two sides equal again. 
East Berlin was a very important city in history. It served as the capital of East Germany from 1949 until 1990. 
Life in the city changed in many ways over the years. In the Soviet sector, a local government was set up to lead. When East Germany was formed in 1949, it chose East Berlin as its capital. 
Many people wanted to move from East Berlin to West Berlin. By 1960, more than 1,000 people were leaving each day. They wanted better lives and a stronger economy. The East German government tried to stop this movement. In August 1961, they built the Berlin Wall. 
East Berlin had a growing number of people living there. In 1961, the population was under 1.06 million people. By 1988, the population grew to 1.28 million people. 
Everything changed on October 3, 1990. This was the day Germany was officially reunified. East and West Berlin finally became one single city again. The two sides had to work hard to join together. The government spent a lot of money to fix the streets and buildings. They wanted the services in the East to match the West. Today, you can still see the history of the city. You might see special traffic lights with little men on them. These are called Ampelmännchen and they are a famous symbol of the East.
East Berlin served as the capital of the German Democratic Republic (GDR) from 1949 to 1990. 
The governance of the city changed through several distinct stages. Initially, the Allied Forces administered the city together through the Allied Kommandatura. This was a joint governing body for all sectors. However, this cooperation broke apart in 1948 when the Soviet representative left. Following this, a separate city government was established in the Soviet sector. When the GDR was founded in 1949, it claimed East Berlin as its capital. This claim was recognized by all communist countries, though Western Allies did not recognize East Berlin as a true capital.
Administratively, the city was managed by a body called the Magistrate of East Berlin. This municipal government met in the Red City Hall. 
Economic and social pressures caused significant movement within the city. By 1960, more than 1,000 East Germans were escaping to West Berlin every day. This exodus was caused by war reparations owed to the Soviet Union and a lack of Marshall Plan assistance. The destruction of industry also strained the East German economy. To stop this population loss, the East German government built the Berlin Wall in August 1961. This wall physically separated East Berlin from West Berlin until November 1989. Crossing the wall was very dangerous because armed soldiers were trained to shoot illegal emigrants.
The population of East Berlin fluctuated during its existence. The lowest population was recorded in 1961, with under 1.06 million people. 
On October 3, 1990, East and West Berlin formally reunited as one city. 
Today, the history of East Berlin remains visible in the city's unique character. The former East has a distinct visual style called Socialist Classicism. It also retains many prewar façades and streetscapes. Some street names still honor socialist figures, such as Karl-Marx-Allee. Another famous icon is the Ampelmännchen, which are stylized little men on pedestrian traffic lights. Even decades after reunification, people from the East and West sometimes use different slang or hold different stereotypes about one another. These cultural differences serve as a lasting connection to the city's divided past.
