Russia, or the Russian Federation, is a country in Eastern Europe and North Asia. It is the largest country in the world, spanning eleven time zones and sharing land borders with fourteen countries. With a population of over 140 million, Russia is the most populous country in Europe and the ninth-most populous in the world. It is a highly urbanised country, with sixteen of its urban areas having more than 1 million inhabitants. Moscow, the most populous metropolitan area in Europe, is the capital and largest city of Russia, while Saint Petersburg is its second-largest city and a major cultural centre.
Human settlement on modern Russian territory dates back to the Lower Paleolithic. The emergence of the East Slavs as a prominent group in Europe between the 3rd and 8th centuries AD led to the establishment of Kievan Rus' in the 9th century, which adopted Orthodox Christianity from the Byzantine Empire in 988. Following its disintegration, the late medieval Grand Principality of Moscow led the unification of Russian lands, culminating in the formation of the Tsardom of Russia in 1547. By the early 18th century, Russia had expanded vastly through conquest, annexation, and the efforts of Russian explorers. It was proclaimed as the Russian Empire in 1721, which became the third-largest empire in history. The Russian Revolution of 1917 led to the abolition of the Russian monarchy and the creation of the Russian SFSR, the first socialist state. Following the Russian Civil War, Russia became the largest and principal constituent of the newly established Soviet Union in 1922. Amidst rapid industrialisation in the 1930s, millions died under Joseph Stalin. The Soviet Union played a decisive role for the Allies in World War II by leading large-scale efforts on the Eastern Front. During the Cold War, it emerged as a superpower and competed with the United States for ideological dominance. The Soviet era saw some of the most significant Russian technological achievements, including the first human-made satellite and the first human expedition into outer space.
In 1991, the Russian SFSR emerged from the dissolution of the Soviet Union as the Russian Federation. Following a constitutional crisis in 1993, a new constitution was adopted, establishing a semi-presidential republic. Since 1999, Russia's political system has been dominated by Vladimir Putin, under whose leadership it has experienced democratic backsliding, transforming into an authoritarian regime. Russia has been militarily involved in numerous conflicts, including its war with Georgia in 2008 and its war with Ukraine since 2014, which in the latter has involved the internationally unrecognised annexation of Crimea in 2014 and four additional regions following the 2022 Russian invasion of Ukraine, resulting in a full-scale war.
Russia is generally considered a great power and wields significant regional influence in Europe, possessing the largest stockpile of nuclear weapons and having the third-highest military expenditure in the world. Its economy ranks among the largest in the world by both nominal GDP and PPP-adjusted GDP, relying on its vast mineral and energy resources, mainly oil and natural gas. Russia continues to rank very low in measurements of democracy, human rights and media freedom, while having high levels of corruption. As the successor state of the Soviet Union, it retains its seat as a permanent member of the United Nations Security Council and is a member state of several international organisations. Russia is also home to 32 UNESCO World Heritage Sites.
Etymology
According to the Oxford English Dictionary, the English name Russia first appeared in the 14th century, borrowed from Medieval Latin: Russia, used in the 11th century and frequently in 12th-century British sources, in turn derived from Russi, 'the Russians' and the suffix -ia.
There are several words in Russian which translate to "Russians" in English. The noun and adjective русский, russkiy refers to ethnic Russians. The adjective российский, rossiiskiy denotes Russian citizens regardless of ethnicity. The same applies to the more recently coined noun россиянин, rossiianyn, in the sense of citizen of the Russian state.
The oldest endonyms used were Rus' (Русь) and the "Russian land" (Русская земля, Russkaya zemlya). According to the Primary Chronicle, the word Rus' is derived from the Rus' people, who were a Swedish tribe, and from where the three original members of the Rurikid dynasty came from. The Finnish word for Swedes, ruotsi, has the same origin. In modern historiography, the early medieval East Slavic state is usually referred to as Kievan Rus', named after its capital city. Another Medieval Latin name for Rus' was Ruthenia.
In Russian, the current name of the country, Россия (Rossiya), comes from the Byzantine Greek name Ρωσία (Rosía). The name Росия (Rosiya) was first attested in 1387. The name Rossiya appeared in Russian sources in the 15th century and began to replace the vernacular Rus' during the rise of Moscow as the centre of a unified Russian state. However, until the end of the 17th century, the country was more often referred to by its inhabitants as Rus', the "Russian land" (Russkaya zemlya), or the "Muscovite state" (Moskovskoye gosudarstvo), among other variations.
In 1721, Peter the Great proclaimed the Russian Empire (Rossiyskaya imperiya). The name Rossiya was used as the common designation for the multinational Russian Empire and then for the modern Russian state. Rossiya is distinguished from the ethnonym russkiy, as it refers to a supranational identity, including ethnic Russians. After the Russian Revolution and the proclamation of the Russian SFSR in 1918, the "Russian" in the title of the state was Rossiyskaya, rather than Russkaya, as the former denoted a multinational state, while the latter had ethnic dimensions. In modern Russian, the name Rus' is still used in poetry or prose to refer to either the older Russia or an imagined essence of Russia.
History
Early history
The first human settlement on Russia dates back to the Oldowan period in the early Lower Paleolithic. About 2 million years ago, representatives of Homo erectus migrated to the Taman Peninsula in southern Russia. Flint tools, some 1.5 million years old, have been discovered in the North Caucasus. Radiocarbon dated specimens from Denisova Cave in the Altai Mountains estimate the oldest Denisovan specimen lived 195–122,700 years ago. Fossils of Denny, an archaic human hybrid that was half Neanderthal and half Denisovan, and lived some 90,000 years ago, was also found within the latter cave. Russia was home to some of the last surviving Neanderthals, from about 45,000 years ago, found in Mezmaiskaya cave.
The first trace of an early modern human in Russia dates back to 45,000 years, in Western Siberia. The discovery of high concentration cultural remains of anatomically modern humans, from at least 40,000 years ago, was found at Kostyonki–Borshchyovo, and at Sungir, dating back to 34,600 years ago—both in western Russia. Humans reached Arctic Russia at least 40,000 years ago, in Mamontovaya Kurya. Ancient North Eurasian populations from Siberia genetically similar to Mal'ta–Buret' culture and Afontova Gora were an important genetic contributor to Ancient Native Americans and Eastern Hunter-Gatherers.
The Kurgan hypothesis places the Volga-Dnieper region of southern Russia and Ukraine as the urheimat of the Proto-Indo-Europeans. Early Indo-European migrations from the Pontic–Caspian steppe of Ukraine and Russia spread Yamnaya ancestry and Indo-European languages across large parts of Eurasia. Nomadic pastoralism developed in the Pontic–Caspian steppe beginning in the Chalcolithic. Remnants of these steppe civilisations were discovered in places such as Ipatovo, Sintashta, Arkaim, and Pazyryk, which bear the earliest known traces of horses in warfare. The genetic makeup of speakers of the Uralic language family in northern Europe was shaped by migration from Siberia that began at least 3,500 years ago.
In the 3rd to 4th centuries AD, the Gothic kingdom of Oium existed in southern Russia, which was later overrun by Huns. Between the 3rd and 6th centuries AD, the Bosporan Kingdom, which was a Hellenistic polity that succeeded the Greek colonies, was also overwhelmed by nomadic invasions led by warlike tribes such as the Huns and Eurasian Avars. The Khazars, who were of Turkic origin, ruled the steppes between the Caucasus in the south, to the east past the Volga river basin, and west as far as Kiev on the Dnieper river until the 10th century. After them came the Pechenegs who created a large confederacy, which was subsequently taken over by the Cumans and the Kipchaks.
The ancestors of Russians are among the Slavic tribes that separated from the Proto-Indo-Europeans, who appeared in the northeastern part of Europe c. 1500 years ago. The East Slavs gradually settled western Russia (approximately between modern Moscow and Saint-Petersburg) in two waves: one moving from Kiev towards present-day Suzdal and Murom and another from Polotsk towards Novgorod and Rostov. Prior to Slavic migration, that territory was populated by Finno-Ugrian peoples. From the 7th century onwards, the incoming East Slavs slowly assimilated the native Finno-Ugrians.
Kievan Rus'
The establishment of the first East Slavic states in the 9th century coincided with the arrival of the Varangians, Vikings who ventured along the waterways extending from the eastern Baltic to the Black and Caspian Seas. According to the Primary Chronicle, a Varangian from the Rus', named Rurik, was elected ruler of Novgorod in 862. In 882, his successor Oleg ventured south and conquered Kiev, which had been previously paying tribute to the Khazars. Rurik's son Igor and Igor's son Sviatoslav subsequently subdued all local East Slavic tribes to Kievan rule, destroyed the Khazar state, and launched several military expeditions to Bulgaria, Byzantium and Persia.
During the 10th and 11th centuries, Kievan Rus' became one of the largest and most prosperous states in Europe. The reigns of Vladimir the Great (980–1015) and his son Yaroslav the Wise (1019–1054) constitute Kiev's Golden Age. Through his political and religious reforms, Vladimir laid the foundations for the transformation of Kievan Rus' from a fragmented conglomeration of tributary groups into a more unified realm, connected by dynastic authority and shared religious and cultural ties. He adopted Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that would define Russian culture for the next millennium. The reign of Yaroslav also saw the creation of the state's first written legal code, the Russkaya Pravda.
Kievan Rus' was politically unstable due to weak centralisation and the absence of a stable succession principle. The rota system introduced by Yaroslav led to princely authority being distributed among members of the ruling Rurikid dynasty according to seniority. Intended to preserve dynastic unity, this system increasingly fostered rivalry among princes, leading to frequent infighting. As a result, political power fragmented among competing regional centres, marking a gradual shift toward decentralisation. Kiev's dominance waned, to the benefit of Vladimir-Suzdal in the north-east, the Novgorod Republic in the north, and Galicia–Volhynia in the south-west. By the 12th century, Kiev lost its pre-eminence and Kievan Rus' had fragmented into different principalities. Prince Andrey Bogolyubsky sacked Kiev in 1169 and made Vladimir his base, leading to political power being shifted to the north-east.
Vladimir-Suzdal continued the tradition of strong princely rule, while the Novgorod Republic, which formally won its independence in 1136, was an exception. From the mid-13th century, the throne of Novgorod was held by the grand princes of Vladimir, although the prince's authority gradually diminished in favour of more republican-style governance, with political power increasingly held by the veche (popular assembly) and elected officials. Novgorod became a major commercial centre through the fur trade and an important centre of Russian culture. Led by Prince Alexander Nevsky, the Novgorodians repelled the invading Swedes in the Battle of the Neva in 1240, as well as the Germanic crusaders in the Battle on the Ice in 1242.
Kievan Rus' finally fell to the Mongol invasions of 1237–1240, which resulted in the sacking of Kiev and other cities, as well as the death of a major part of the population. The invaders, later known as Tatars, formed the state of the Golden Horde, which ruled over Russia for the next two centuries. Only the Novgorod Republic escaped foreign occupation after it agreed to pay tribute to the Mongols. Galicia–Volhynia would later be absorbed by Lithuania and Poland, while the Novgorod Republic continued to prosper in the north. In the northeast, the Byzantine-Slavic traditions of Kievan Rus' were adapted to form the Russian autocratic state.
Grand Principality of Moscow
The destruction of Kievan Rus' saw the eventual rise of the Grand Principality of Moscow, initially a part of Vladimir-Suzdal. While still under the domain of the Mongol-Tatars and with their connivance, Moscow began to assert its influence in the region in the early 14th century, gradually becoming the leading force in the "gathering of the Russian lands". When the seat of the metropolitan of the Russian Orthodox Church moved to Moscow in 1325, its influence increased. Moscow's last rival, the Novgorod Republic, prospered as the chief fur trade centre and the easternmost port of the Hanseatic League.
Led by Prince Dmitry Donskoy of Moscow, the united army of Russian principalities inflicted a milestone defeat on the Mongol-Tatars in the Battle of Kulikovo in 1380. Moscow gradually absorbed its parent duchy and surrounding principalities, including formerly strong rivals such as Tver and Novgorod.
Ivan III ("the Great") threw off the control of the Golden Horde and gained sovereignty over the ethnically Russian lands; he later adopted the title of sovereign of all Russia. After the fall of Constantinople in 1453, Moscow claimed succession to the legacy of the Eastern Roman Empire. Ivan III married Sophia Palaiologina, the niece of the last Byzantine emperor Constantine XI, and made the Byzantine double-headed eagle his own, and eventually Russia's, coat-of-arms. Vasili III united all of Russia by annexing the last few independent Russian states in the early 16th century.
Tsardom of Russia
In development of the Third Rome ideas, the grand prince Ivan IV ("the Terrible") was officially crowned as the first tsar of all Russia in 1547. The tsar promulgated a new code of laws (Sudebnik of 1550), established the first Russian feudal representative body (the Zemsky Sobor), revamped the military, curbed the influence of the clergy, and reorganised local government. During his long reign, Ivan nearly doubled the already large Russian territory by annexing the three Tatar khanates: Kazan and Astrakhan along the Volga, and the Khanate of Sibir in southwestern Siberia. Ultimately, by the end of the 16th century, Russia expanded east of the Ural Mountains. However, the Tsardom was weakened by the long and unsuccessful Livonian War against the coalition of the Kingdom of Poland and the Grand Duchy of Lithuania (later the united Polish–Lithuanian Commonwealth), the Kingdom of Sweden, and Denmark–Norway for access to the Baltic coast and sea trade. In 1571, the Crimean Tatars, supported by the Ottomans, burned down Moscow, destroying everything except the Kremlin. The following year, the Crimeans attempted another raid on Moscow, but this time they were defeated in the crucial Battle of Molodi.
The death of Ivan's sons marked the end of the ancient Rurik dynasty in 1598, and in combination with the famine of 1601–1603, led to a civil war, the rule of pretenders, and foreign intervention during the Time of Troubles in the early 17th century. The Polish–Lithuanian Commonwealth, taking advantage, occupied parts of Russia, extending into the capital Moscow. In 1612, the Poles were forced to retreat by the Russian volunteer corps, led by merchant Kuzma Minin and prince Dmitry Pozharsky. The Romanov dynasty acceded to the throne in 1613 by the decision of the Zemsky Sobor, and the country started its gradual recovery from the crisis.
Russia continued its territorial growth through the 17th century, which was the age of the Cossacks. In 1654, the Ukrainian leader, Bohdan Khmelnytsky, offered to place Ukraine under the protection of the Russian tsar, Alexis, whose acceptance of this offer led to another Russo-Polish War. Ultimately, Ukraine was split along the Dnieper, placing Left-bank Ukraine and Kiev under Russian rule. In the east, the rapid Russian exploration and colonisation of vast Siberia continued, hunting for valuable furs and ivory. Russian explorers pushed eastward primarily along the Siberian River Routes, and by the mid-17th century, there were Russian settlements in eastern Siberia, on the Chukchi Peninsula, along the Amur River, and on the coast of the Pacific Ocean. In 1648, Semyon Dezhnyov became the first European to navigate through the Bering Strait.
Imperial Russia
Under Peter the Great, Russia was proclaimed an empire in 1721, and established itself as one of the European great powers. Ruling from 1682 to 1725, Peter defeated Sweden in the Great Northern War (1700–1721), securing Russia's access to the sea and sea trade. In 1703, Peter founded Saint Petersburg on the Baltic Sea by establishing the Peter and Paul Fortress as a strategic outpost; the city later replaced Moscow as Russia's capital in 1712. Throughout his rule, sweeping reforms were made, which brought significant Western European cultural influences to Russia. He was succeeded by Catherine I (1725–1727), followed by Peter II (1727–1730), and Anna. The reign of Peter I's daughter Elizabeth from 1741 to 1762 saw Russia's participation in the Seven Years' War (1756–1763). During the conflict, Russian troops overran East Prussia, reaching Berlin. However, upon Elizabeth's death, all these conquests were returned to the Kingdom of Prussia by pro-Prussian Peter III of Russia.
Catherine II ("the Great"), who ruled from 1762 to 1796, presided over the Russian Age of Enlightenment. She extended Russian political control over the Polish–Lithuanian Commonwealth and annexed most of its territories into Russia, making it the most populous country in Europe. In the south, after the successful Russo-Turkish Wars against the Ottoman Empire, Catherine advanced Russia's boundary to the Black Sea, by dissolving the Crimean Khanate, and annexing Crimea. As a result of victories over Qajar Iran through the Russo-Persian Wars, by the first half of the 19th century, Russia also conquered the Caucasus. Catherine's successor, her son Paul, was unstable and focused predominantly on domestic issues. Following his short reign, Catherine's strategy was continued with Alexander I's (1801–1825) wresting of Finland from the weakened Sweden in 1809, and of Bessarabia from the Ottomans in 1812. In North America, the Russians became the first Europeans to reach and colonise Alaska. In 1803–1806, the first Russian circumnavigation was made. In 1820, a Russian expedition discovered the continent of Antarctica.
Great power and development of society, sciences, and arts
During the Napoleonic Wars, Russia joined alliances with various European powers, and fought against France. The French invasion of Russia at the height of Napoleon's power in 1812 reached Moscow, but eventually failed as the obstinate resistance in combination with the bitterly cold Russian winter led to a disastrous defeat of invaders, in which the pan-European Grande Armée faced utter destruction. Led by Mikhail Kutuzov and Michael Andreas Barclay de Tolly, the Imperial Russian Army ousted Napoleon and drove throughout Europe in the War of the Sixth Coalition, ultimately entering Paris. Alexander I controlled Russia's delegation at the Congress of Vienna, which defined the map of post-Napoleonic Europe.
The officers who pursued Napoleon into Western Europe brought ideas of liberalism back to Russia, and attempted to curtail the tsar's powers during the abortive Decembrist revolt of 1825. At the end of the conservative reign of Nicholas I (1825–1855), a zenith period of Russia's power and influence in Europe, was disrupted by defeat in the Crimean War.
Great liberal reforms and capitalism
Nicholas's successor Alexander II (1855–1881) enacted significant changes throughout the country, including the emancipation reform of 1861. These reforms spurred industrialisation, and modernised the Imperial Russian Army, which liberated much of the Balkans from Ottoman rule in the aftermath of the 1877–1878 Russo-Turkish War. During most of the 19th and early 20th centuries, Russia and Britain colluded over Afghanistan and its neighbouring territories in Central and South Asia; the rivalry between the two major European empires came to be known as the Great Game.
The late 19th century saw the rise of various socialist movements in Russia. Alexander II was assassinated in 1881 by revolutionary terrorists. The reign of his son Alexander III (1881–1894) was less liberal but more peaceful.
Constitutional monarchy and World War
During the reign of the last Russian emperor, Nicholas II (1894–1917), the Revolution of 1905 was precipitated by the disastrous and humiliating defeat in the Russo-Japanese War. The uprising was put down, but the government was forced to concede major reforms (Russian Constitution of 1906), including granting freedoms of speech and assembly, the legalisation of political parties, and the creation of an elected legislative body, the State Duma.
Revolution and civil war
In 1914, Russia entered World War I in response to Austria-Hungary's declaration of war on Russia's ally Serbia, and fought across multiple fronts while isolated from its Triple Entente allies. In 1916, the Brusilov Offensive of the Imperial Russian Army almost completely destroyed the Austro-Hungarian Army. However, the already-existing public distrust of the regime was deepened by the rising costs of war, high casualties, and rumours of corruption and treason. All this formed the climate for the Russian Revolution of 1917, carried out in two major acts. In early 1917, Nicholas II was forced to abdicate; he and his family were imprisoned and later executed during the Russian Civil War. The monarchy was replaced by a shaky coalition of political parties that declared itself the Provisional Government, and proclaimed the Russian Republic. On 19 January [O.S. 6 January], 1918, the Russian Constituent Assembly declared Russia a democratic federal republic (thus ratifying the Provisional Government's decision). The next day the Constituent Assembly was dissolved by the All-Russian Central Executive Committee.
An alternative socialist establishment co-existed, the Petrograd Soviet, wielding power through the democratically elected councils of workers and peasants, called soviets. The rule of the new authorities only aggravated the crisis in the country instead of resolving it, and eventually, the October Revolution, led by Bolshevik leader Vladimir Lenin, overthrew the Provisional Government and gave full governing power to the soviets, leading to the creation of the world's first socialist state. The Russian Civil War broke out between the anti-communist White movement and the Bolsheviks with its Red Army. In the aftermath of signing the Treaty of Brest-Litovsk that concluded hostilities with the Central Powers of World War I, Bolshevist Russia surrendered most of its western territories, which hosted 34% of its population, 54% of its industries, 32% of its agricultural land, and roughly 90% of its coal mines.
The Allied powers launched an unsuccessful military intervention in support of anti-communist forces. In the meantime, both the Bolsheviks and White movement carried out campaigns of deportations and executions against each other, known respectively as the Red Terror and White Terror. By the end of the violent civil war, Russia's economy and infrastructure were heavily damaged, and as many as 10 million perished during the war, mostly civilians. Millions became White émigrés, and the Russian famine of 1921–1922 claimed up to five million victims.
Soviet Union
Command economy and Soviet society
On 30 December 1922, Lenin and his aides formed the Soviet Union, by joining the Russian SFSR into a single state with the Byelorussian, Transcaucasian, and Ukrainian republics. Eventually, internal border changes and annexations during World War II resulted in a union of 15 republics, the largest and most populous being the Russian SFSR, which dominated the union politically, culturally, and economically.
Following Lenin's death in 1924, a troika was designated to take charge. Eventually Joseph Stalin, the General Secretary of the Communist Party, managed to suppress all opposition factions and consolidate power in his hands to become the country's dictator by the 1930s. Leon Trotsky, the main proponent of world revolution, was exiled from the Soviet Union in 1929, and Stalin's idea of Socialism in One Country became the official line. The continued internal struggle in the Bolshevik party culminated in the Great Purge.
Stalinism and modernisation
Under Stalin's leadership, the government launched a command economy, industrialisation of the largely rural country, and collectivisation of its agriculture. During this period of rapid economic and social change, millions of people were sent to penal labour camps, including many political convicts for their suspected or real opposition to Stalin's rule, and millions were deported and exiled to remote areas of the Soviet Union. The transitional disorganisation of the country's agriculture, combined with the harsh state policies and a drought, led to the Soviet famine of 1932–1933, which killed 5.7 to 8.7 million, 3.3 million of them in the Russian SFSR. The Soviet Union, ultimately, made the costly transformation from a largely agrarian economy to a major industrial powerhouse within a short span of time.
World War II and United Nations
The Soviet Union entered World War II on 17 September 1939 with its invasion of Poland, in accordance with a secret protocol within the Molotov–Ribbentrop Pact with Nazi Germany. The Soviet Union later invaded Finland, and occupied and annexed the Baltic states, as well as parts of Romania. On 22 June 1941, Germany invaded the Soviet Union, opening the Eastern Front, the largest theatre of World War II.
Eventually, some 5 million Red Army troops were captured by the Nazis; the latter deliberately starved to death or otherwise killed 3.3 million Soviet POWs, and a vast number of civilians, as the "Hunger Plan" sought to fulfil Generalplan Ost. Although the Wehrmacht had considerable early success, their attack was halted in the Battle of Moscow. Subsequently, the Germans were dealt major defeats first at the Battle of Stalingrad in the winter of 1942–1943, and then in the Battle of Kursk in the summer of 1943. Another German failure was the Siege of Leningrad, in which the city was fully blockaded on land between 1941 and 1944 by German and Finnish forces, and suffered starvation and more than a million deaths, but never surrendered. Soviet forces steamrolled through Eastern and Central Europe in 1944–1945 and captured Berlin in May 1945. In August 1945, the Red Army invaded Manchuria and ousted the Japanese from Northeast Asia, contributing to the Allied victory over Japan.
The 1941–1945 period of World War II is known in Russia as the Great Patriotic War. The Soviet Union, along with the United States, the United Kingdom and China were considered the Big Four of Allied powers in World War II, and later became the Four Policemen, which was the foundation of the United Nations Security Council. During the war, Soviet civilian and military death were about 26–27 million, accounting for about half of all World War II casualties. The Soviet economy and infrastructure suffered massive devastation, which caused the Soviet famine of 1946–1947. However, at the expense of a large sacrifice, the Soviet Union emerged as a superpower.
Superpower and Cold War
After World War II, according to the Potsdam Conference, the Red Army occupied parts of Eastern and Central Europe, including East Germany and the eastern regions of Austria. Dependent communist governments were installed in the Eastern Bloc satellite states. After becoming the world's second nuclear power, the Soviet Union established the Warsaw Pact alliance, and entered into a struggle for global dominance, known as the Cold War, with the rivalling United States and NATO.
Khrushchev Thaw reforms and economic development
After Stalin's death in 1953 and a short period of collective leadership, the new leader Nikita Khrushchev denounced Stalin and launched the policy of de-Stalinization, releasing many political prisoners from the Gulag labour camps. The general easement of repressive policies became known later as the Khrushchev Thaw. At the same time, Cold War tensions reached its peak when the two rivals clashed over the deployment of the United States Jupiter missiles in Turkey and Soviet missiles in Cuba.
