From the History of Russia

The history of Russia begins from the year 862. The first Russian state had the towns of Kiev, Novgorod, Vladimir. In the X century one of the Russian princes, Svyatoslav, began the process of assimilation of Russian lands. His son, Vladimir, introduced Christianity as the state religion. It happened in 988.

With the development of feudalism the country became separated into several parts. And Tatar-Mongols easily conquered the country. It happened in 1240. The occupation lasted for three hundred years.

The first tzar of Russia was Ivan the Fourth, or Ivan the Terrible. He was a talented military-man and a tyrant After his death there had been the Time of Troubles in 1598—1613. It ended with the election of Mikhail Romanov as a tzar.

Peter the Great, one of the tzars from the Romanov dynasty, introduced the European culture in Russia. He reformed Russian education and Russian army. He organized the Academy of Sciences and a lot of other institutions. He enlarged the borders of the Russian state. In 1721 he assumed the title of the Emperor.

Since that time Russia was called the Russian Empire.

Many of his reforms were continued by the Empresses Elizabeth and Katherine. By the end of the XVIII century Russia had become a European state.

In the XIX century Russia had a great victory over the Napoleonic Army in 1812. And it had become one of the leading countries in Europe.

Tzar Alexander the II ended the institute of serfdom in 1861. And the country began developing the capitalist relations. Russia took part in many wars — the Napoleonic Wars, the Crimean War, the Balkan Wars and many others. The prestige of the Russian state grew.

But the World War I was a terrible event for the nation. Our country lost more than a million men at the war.

In February 1917 the Romanov dynasty was overthrown. And in October the Great October Revolution took place.

Russia withdrew out of the World War I, fought its enemies in the Civil War and at last the Soviet Union was formed.

In the 1930s the country underwent rapid industrialization and collectivization. A lot of factories and plants were built. The authority of our country in the world was hard to overestimate. The Soviet Union played the main part in the defeat of the fascist Germany. In the years 1960—1980 the influence of the Soviet Union was worldwide.

In the year 1985 Gorbachev started the restructuring process.

In the year 1991 the Soviet Union stopped its existence.
