The Soviet Union was originally the
Russian Empire. The tsar, or emperor,
fell from power in a revolution that took
place in 1917. Later in the same year a
group called the Bolsheviks came to
power. This group, later renamed the
Communist Party, fought other Russians
in a civil war that lasted from 1918 to
1920. Vladimir Lenin led the Communists.
The Communists won the war.
Early Years
On December 20, 1922, the Communists
created the Union of Soviet Socialist
Republics. Russia was one of its
republics. The other republics were
mostly regions of the former Russian
Empire. They were home to various
non-Russian groups.
Lenin died in 1924. A few years later, a
Communist Party leader named Joseph
Stalin came to power. Stalin was one of
the cruelest rulers who ever lived. He
killed farmers who did not want collective
farms. He sold crops to foreign
countries and let his own people starve.
During the 1930s he caused as many as
10 million people in the Soviet Union to
die.
WorldWar II
In 1939, just beforeWorldWar II
began, Germany and the Soviet Union
secretly agreed not to attack each other.
Germany then invaded Poland, which
started the war. Germany and the Soviet
Union divided Poland between them.
The Soviet Union also took Latvia,
Lithuania, and Estonia at this time and
made them Soviet republics.
In June 1941, however, Germany broke
the agreement and invaded the Soviet
Union. The Soviet Union then joined
the United States and Great Britain to
fight Germany.
The Soviet Union suffered terribly during
the war. By the time Germany surrendered
in 1945 more than 20 million
Soviet people had died.
ColdWar
Despite all the damage it had suffered,
the Soviet Union was still the greatest
power in Europe afterWorldWar II.
While fighting the Germans, Soviet
troops moved into many countries in
eastern Europe. Between 1945 and 1948
the Soviets set up Communist governments
in these countries. They con-

trolled these governments. This activity
worried many people in other countries,
particularly the United States. Both
countries built up their military forces.
The rivalry between them came to be
known as the ColdWar.
The United States and the Soviet Union
both developed nuclear weapons. Many
people were afraid that this would lead
to nuclear war. But neither country ever
used the weapons.
Conditions improved for the Soviet
people following Stalin’s death in 1953.
Over the next few years Nikita Khrushchev
came to power. Khrushchev introduced
some reforms that angered other
Communist party leaders. In 1964 he
lost power.
Some eastern European countries tried
to take advantage of the reforms. They
rose up against Soviet rule. To stop the
uprisings, the Soviet Union invaded
Hungary in 1956 and Czechoslovakia in
1968.
The Soviets invaded Afghanistan in
1979. Afghanistan is an Asian country
that bordered the Soviet Union. Rebels
there were trying to overthrow a Communist
government. The United States
supported the rebels. In 1989 the Soviet
Union left Afghanistan in defeat.
Breakup
In 1985 Mikhail Gorbachev came to
power. Gorbachev wanted to build a
stronger economy and a freer society.
His policies were called glasnost, which
means “openness,” and perestroika,
which means “restructuring.” But Gorbachev
soon learned that the more freedom
his people had, the more they
wanted. Beginning in 1987 people in
some of the Soviet republics began to
demand independence.
In 1989 a series of almost completely
peaceful revolutions began. The eastern
European countries gained independence
from Soviet control. During 1991
the Soviet republics also gained their
independence. On the last day of that
year, the Soviet Union came to an end.
Fifteen separate countries replaced it.

United Arab Emirates
The United Arab Emirates is a small,

Geography
The country is a union of seven small
kingdoms, or emirates. The emirate

country’s land. It stretches along the
Persian Gulf, to the north. The other six
emirates are in the northeast. The country
shares borders with Saudi Arabia and
Oman. Most of the land is a flat desert.
