Erected in the dead of night on August 13, 1961, the Berlin Wall (known as Berliner Mauer in German) was a physical division between West Berlin and East Germany. Its purpose was to keep disaffected East Germans from fleeing to the West.

When the Berlin Wall fell on November 9, 1989, its destruction was nearly as instantaneous as its creation. For 28 years, the Berlin Wall had been a symbol of the Cold War and the Iron Curtain between Soviet-led Communism and the democracies of the West. When it fell, the event was celebrated around the world.

A Divided Germany and Berlin

At the end of World War II, the Allied powers divided conquered Germany into four zones. As agreed at the July 1945 Potsdam Conference, each was occupied by either the United States, Great Britain, France, or the Soviet Union. The same was done in Germany's capital city, Berlin.

The relationship between the Soviet Union and the other three Allied powers quickly disintegrated. As a result, the cooperative atmosphere of the occupation of Germany turned competitive and aggressive. One of the best-known incidents was the Berlin Blockade in June of 1948 during which the Soviet Union stopped all supplies from reaching West Berlin.

Although an eventual reunification of Germany had been intended, the new relationship between the Allied powers turned Germany into West versus East and democracy versus Communism.

In 1949, this new organization of Germany became official when the three zones occupied by the United States, Great Britain, and France combined to form West Germany (the Federal Republic of Germany, or FRG). The zone occupied by the Soviet Union quickly followed by forming East Germany (the German Democratic Republic, or GDR).

This same division into West and East occurred in Berlin. Since the city of Berlin had been situated entirely within the Soviet Zone of Occupation, West Berlin became an island of democracy within Communist East Germany.

The Economic Differences

Within a short period of time after the war, living conditions in West Germany and East Germany became distinctly different.

With the help and support of its occupying powers, West Germany set up a capitalist society. The economy experienced such a rapid growth that it became known as the "economic miracle." With hard work, individuals living in West Germany were able to live well, buy gadgets and appliances, and travel as they wished.

Nearly the opposite was true in East Germany. The Soviet Union had viewed their zone as a spoil of war. They pilfered factory equipment and other valuable assets from their zone and shipped them back to the Soviet Union.

When East Germany became its own country in 1949, it was under the direct influence of the Soviet Union and a Communist society was established. The economy of East Germany dragged and individual freedoms were severely restricted.

Mass Emigration From the East

Outside of Berlin, East Germany had been fortified in 1952. By the late 1950s, many people living in East Germany wanted out. No longer able to stand the repressive living conditions, they decided to head to West Berlin. Although some of them would be stopped on their way, hundreds of thousands made it across the border.﻿﻿

Once across, these refugees were housed in warehouses and then flown to West Germany. Many of those who escaped were young, trained professionals. By the early 1960s, East Germany was rapidly losing both its labor force and its population.

Scholars estimate that between 1949 and 1961, nearly 3 million of the GDR's 18 million populace fled East Germany.﻿﻿ The government was desperate to stop this mass exodus, and the obvious leak was the easy access East Germans had to West Berlin.

What to Do About West Berlin

With the support of the Soviet Union, there had been several attempts to simply take over the city of West Berlin. Although the Soviet Union even threatened the United States with the use of nuclear weapons over this issue, the United States and other Western countries were committed to defending West Berlin.

Desperate to keep its citizens, East Germany knew that something needed to be done. Famously, two months before the Berlin Wall appeared, Walter Ulbricht, Head of the State Council of the GDR (1960–1973) said, "Niemand hat die Absicht, eine Mauer zu errichten." These iconic words mean, "No one intends to build a wall."

After this statement, the exodus of East Germans only increased. Over those next two months of 1961, nearly 20,000 people fled to the West.﻿﻿

The Berlin Wall Goes Up

Rumors had spread that something might happen to tighten the border of East and West Berlin. No one was expecting the speed—nor the absoluteness—of the Berlin Wall.

Just after midnight on the night of August 12–13, 1961, trucks with soldiers and construction workers rumbled through East Berlin. While most Berliners were sleeping, these crews began tearing up streets that entered into West Berlin. They dug holes to put up concrete posts and strung barbed wire all across the border between East and West Berlin. Telephone wires between East and West Berlin were also cut and railroad lines were blocked.

Berliners were shocked when they woke up that morning. What had once been a very fluid border was now rigid. No longer could East Berliners cross the border for operas, plays, soccer games, or any other activity. No longer could the approximately 50,000–70,000 commuters head to West Berlin for well-paying jobs.﻿﻿ No longer could families, friends, and lovers cross the border to meet their loved ones.

Whichever side of the border one went to sleep on during the night of August 12, they were stuck on that side for decades.

The Size and Scope of the Berlin Wall

The total length of the Berlin Wall was 96 miles (155 kilometers).﻿﻿ It cut not only through the center of Berlin, but also wrapped around West Berlin, entirely cutting it off from the rest of East Germany.

The wall itself went through four major transformations during its 28-year history. It started out as a barbed-wire fence with concrete posts. Just days later, on August 15, it was quickly replaced with a sturdier, more permanent structure. This one was made out of concrete blocks and topped with barbed wire. The first two versions of the wall were replaced by the third version in 1965, consisting of a concrete wall supported by steel girders.

The fourth version of the Berlin Wall, constructed from 1975 to 1980, was the most complicated and thorough. It consisted of concrete slabs reaching nearly 12-feet high (3.6 meters) and 4-ft wide (1.2 m).﻿﻿ It also had a smooth pipe running across the top to hinder people from scaling it.

By the time the Berlin Wall fell in 1989, there was a 300-foot No Man's Land established on the exterior, and an additional inner wall.﻿﻿ Soldiers patrolled with dogs and a raked ground revealed any footprints. The East Germans also installed anti-vehicle trenches, electric fences, massive light systems, 302 watchtowers, 20 bunkers, and even minefields.﻿﻿

Over the years, propaganda from the East German government would say that the people of East Germany welcomed the Wall. In reality, the oppression they suffered and the potential consequences they faced kept many from speaking out to the contrary.

The Checkpoints of the Wall

Although most of the border between East and West consisted of layers of preventative measures, there were little more than a handful of official openings along the Berlin Wall. These checkpoints were for the infrequent use of officials and others with special permission to cross the border.

The most famous of these was Checkpoint Charlie, located on the border between East and West Berlin at Friedrichstrasse. Checkpoint Charlie was the main access point for Allied personnel and Westerners to cross the border. Soon after the Berlin Wall was built, Checkpoint Charlie became an icon of the Cold War, one that has frequently been featured in movies and books set during this time period.

Escape Attempts and the Death Line

The Berlin Wall did prevent the majority of East Germans from emigrating to the West, but it did not deter everyone. During the history of the Berlin Wall, it is estimated that about 5,000 people made it safely across.﻿﻿

Some early successful attempts were simple, like throwing a rope over the Berlin Wall and climbing up. Others were brash, like ramming a truck or bus into the Berlin Wall and making a run for it. Still others were suicidal as some people jumped from the upper-story windows of apartment buildings that bordered the Berlin Wall.

In September 1961, the windows of these buildings were boarded up and the sewers connecting East and West were shut off. Other buildings were torn down to clear space for what would become known as the Todeslinie, the "Death Line" or "Death Strip." This open area allowed a direct line of fire so East German soldiers could carry out Shiessbefehl, a 1960 order that they were to shoot anyone trying escape. At least 12 were killed within the first year.﻿﻿

As the Berlin Wall became stronger and larger, escape attempts became more elaborately planned. Some people dug tunnels from the basements of buildings in East Berlin, under the Berlin Wall, and into West Berlin. Another group saved scraps of cloth and built a hot air balloon and flew over the Wall.

Unfortunately, not all escape attempts were successful. Since the East German guards were allowed to shoot anyone nearing the eastern side without warning, there was always a chance of death in any and all escape plots. At least 140 people died at the Berlin Wall.﻿﻿

The 50th Victim of the Berlin Wall

One of the most infamous cases of a failed attempt occurred on August 17, 1962. In the early afternoon, two 18-year-old men ran toward the Wall with the intention of scaling it. The first of the young men to reach it was successful. The second one, Peter Fechter, was not.

As he was about to scale the Wall, a border guard opened fire. Fechter continued to climb but ran out of energy just as he reached the top. He then tumbled back onto the East German side. To the shock of the world, Fechter was just left there. The East German guards did not shoot him again nor did they go to his aid.

Fechter shouted in agony for nearly an hour. Once he had bled to death, East German guards carried off his body. He became a permanent symbol of the struggle for freedom.

Communism Is Dismantled

The fall of the Berlin Wall happened nearly as suddenly as its rise. There had been signs that the Communist bloc was weakening, but the East German Communist leaders insisted that East Germany just needed a moderate change rather than a drastic revolution. East German citizens did not agree.

Russian leader Mikhail Gorbachev (1985–1991) was attempting to save his country and decided to break off from many of its satellites. As Communism began to falter in Poland, Hungary, and Czechoslovakia in 1988 and 1989, new exodus points were opened to East Germans who wanted to flee to the West.

In East Germany, protests against the government were countered by threats of violence from its leader, Erich Honecker (served 1971–1989). In October 1989, Honecker was forced to resign after losing support from Gorbachev. He was replaced by Egon Krenz who decided that violence was not going to solve the country's problems. Krenz also loosened travel restrictions from East Germany.

The Fall of the Berlin Wall

Suddenly, on the evening of November 9, 1989, East German government official Günter Schabowski blundered by stating in an announcement, "Permanent relocations can be done through all border checkpoints between the GDR [East Germany] into the FRG [West Germany] or West Berlin."

People were in shock. Were the borders really open? East Germans tentatively approached the border and indeed found that the border guards were letting people cross.

Very quickly, the Berlin Wall was inundated with people from both sides. Some began chipping at the Berlin Wall with hammers and chisels. There was an impromptu and massive celebration along the Berlin Wall, with people hugging, kissing, singing, cheering, and crying.

The Berlin Wall was eventually chipped away into smaller pieces (some the size of a coin and others in big slabs). The pieces have become collectibles and are stored in both homes and museums. There is also now a Berlin Wall Memorial at the site on Bernauer Strasse.
