What the USSR was

USSR stands for Union of Soviet Socialist Republics. It was formed on 30 December 1922 out of the wreckage of the Russian Empire and dissolved on 26 December 1991, after sixty-nine years. Its capital was Moscow, and it covered about 22.4 million square kilometres, making it the largest country in the world by area.

It was a federation in name, made up of fifteen union republics (Russia, Ukraine, Belarus, Moldova, the three Baltic states, three Caucasus republics and five in Central Asia), but it was governed as a one-party state by the Communist Party of the Soviet Union. No election could remove the party, and the state controlled industry, press and travel.

During the Cold War it was one of two superpowers, matched only by the United States in nuclear weapons and space capability, and it led a bloc of allied countries in Eastern Europe. By 1991 its population was close to 290 million.

Cold War, space and the collapse

The rivalry produced institutions as well as tension: NATO on one side, the Warsaw Pact from 1955 on the other, and Comecon, the Soviet-led economic bloc, from 1949. Proxy conflicts were fought across Asia, Africa and Latin America while the two sides avoided direct war.

The Soviet record includes Sputnik, the first artificial satellite, in 1957, Yuri Gagarin's first human spaceflight in 1961, and the Mir space station. It also includes the Chernobyl nuclear disaster of 1986 and an economy that stagnated through the 1980s.

Mikhail Gorbachev's glasnost and perestroika loosened controls but sped up the break-up. The Berlin Wall fell in 1989, the republics declared sovereignty through 1991, and the Belovezha Accords of December 1991 replaced the union with the Commonwealth of Independent States. Gorbachev resigned on 25 December 1991 and the Soviet flag came down the next day.

India and the USSR: the 1971 treaty and after

India and the Soviet Union signed the Treaty of Peace, Friendship and Cooperation on 9 August 1971 in New Delhi. Foreign Minister Swaran Singh and Soviet Foreign Minister Andrei Gromyko signed it, under Prime Minister Indira Gandhi. It ran for twenty years and included a clause on mutual consultation in case of a threat, and it came as the East Pakistan crisis was building toward the creation of Bangladesh.

During the 1971 war the Soviet Union supplied weapons and gave India diplomatic cover at the United Nations. The relationship also deepened economically. A rupee-rouble payment arrangement let India buy Soviet machinery without dollars, and the Bhilai and Bokaro steel plants, among other heavy industry, were built with Soviet assistance.

Other links are less remembered. IIT Bombay was set up in 1958 with Soviet help, MiG-21 fighters were built at HAL under licence, and in 1984 Rakesh Sharma flew to the Salyut 7 space station on a Soviet Soyuz mission, becoming the first Indian in space. India stayed formally non-aligned while buying most of its defence equipment from Moscow.

Where you still meet the USSR

Russia took over the Soviet seat at the UN Security Council and inherited much of the arsenal, but fifteen independent countries, Russia included, now occupy the old republic territory, from Ukraine and Belarus to Kazakhstan. Old maps and family stories still say USSR, and the loose Commonwealth of Independent States that replaced it has never held comparable power.

For Indian students the topic appears in history and general awareness sections of SSC, UPSC and state public service exams. The usual questions are about the formation and dissolution dates, the fifteen republics, the 1971 treaty and the Cold War alliance system.

Remembering the dates and terms for exams

A short list helps: 1917 revolution, 1922 formation, 1945 end of the Second World War, 1949 Comecon, 1955 Warsaw Pact, 1957 Sputnik, 1961 Gagarin, 1971 Indo-Soviet treaty, 1985 Gorbachev takes office, 1991 dissolution. Many exam questions combine two of these, for instance asking which event came between the treaty and the collapse.

Do not mix up USSR with Russia, which was only one republic of the union, or with the CIS, which is a looser grouping with no joint army or government. After 1991 India signed a fresh treaty with the Russian Federation in 1993, and the old treaty was not renewed.

The Union of Soviet Socialist Republics vanished on 26 December 1991, but it still shapes exam syllabi, Indian industrial history and the politics of fifteen modern states.

USSR Full Form: Common Questions

What is the full form of USSR?

USSR stands for Union of Soviet Socialist Republics, the communist state that existed from 1922 to 1991 across much of Eurasia, with Moscow as its capital.

How many republics made up the USSR?

Fifteen union republics, from Russia and Ukraine in Europe to Kazakhstan and Uzbekistan in Central Asia. Each had its own government on paper, though real power sat with the Communist Party in Moscow.

Why did the Soviet Union break up?

Economic stagnation, the cost of the arms race, the Chernobyl disaster and political liberalisation under Gorbachev weakened central control. The republics declared sovereignty through 1991, and the union was formally replaced by the CIS in December 1991.

What was India's relationship with the USSR?

Close. The 1971 Indo-Soviet treaty backed India during the Bangladesh war, trade ran through rupee-rouble payments, Soviet aid helped build steel plants and parts of the IIT system, and most Indian defence equipment came from the Soviet bloc.

Is the USSR the same as Russia?

No. Russia was the largest of the fifteen republics in the USSR. After 1991 it became an independent country and the legal successor of the Soviet state at the United Nations.
