at the end of the
Invasion of Poland. At the center Major General
Heinz Guderian and Brigadier
Semyon Krivoshein Stalin arranged the
Molotov–Ribbentrop Pact, a non-aggression pact with
Nazi Germany on 23 August along with the
German-Soviet Commercial Agreement to open economic relations. A secret appendix to the pact gave Eastern Poland, Latvia, Estonia,
Bessarabia and Finland to the USSR, and Western Poland and
Lithuania to Nazi Germany. This reflected the Soviet desire of territorial gains. Following the pact with Hitler, Stalin in 1939–1940 annexed half of Poland, the three Baltic States, and Northern Bukovina and Bessarabia in Romania. They no longer were buffers separating the USSR from German areas, argues Louis Fischer. Rather they facilitated Hitler's rapid advance to the gates of Moscow. Propaganda was also considered an important foreign relations tool. International exhibitions, the distribution of media such as films, e.g.:
Alexander Nevski, as well as inviting prominent foreign individuals to tour the Soviet Union, were used as a method of gaining international influence and encouraging fellow travelers and pacifists to build popular fronts.
Start of World War II Germany
invaded Poland on 1 September; the
USSR followed on 17 September. The Soviets quelled opposition by executing and arresting thousands. They relocated suspect ethnic groups to Siberia in four waves, 1939–1941. Estimates varying from the figure over 1.5 million. After Poland was divided up with Germany, Stalin made territorial demands to Finland, claiming security needs regarding the protection of Leningrad. After the Finns refused the demands, the Soviets invaded Finland on 30 November 1939, launching the
Winter War, with the goal of annexing Finland into the Soviet Union. Despite outnumbering Finnish troops by over 2.5:1, the war proved embarrassingly difficult for the Red Army, which was ill-equipped for the winter weather and lacking competent commanders since the
purge of the Soviet high command. The Finns resisted fiercely, and received some support and considerable sympathy from the Allies. On 29 January 1940, the Soviets put an end to their puppet
Terijoki Government that they had intended on inserting into Helsinki, and informed the Finnish government that the Soviet Union was willing to negotiate peace. The
Moscow Peace Treaty was signed on 12 March 1940, with the war ending the following day. By the terms of the treaty, Finland relinquished the
Karelian Isthmus and some smaller territories. London, Washington—and especially Berlin—calculated that the poor showing of the Soviet army indicated it was incompetent to defend the USSR against a German invasion. In 1940, the USSR
occupied and illegally annexed Lithuania, Latvia, and Estonia. On 14 June 1941, the USSR performed first mass deportations from Lithuania, Latvia, and Estonia. On 26 June 1940 the Soviet government issued an
ultimatum to the Romanian minister in Moscow, demanding the
Kingdom of Romania immediately cede
Bessarabia and
Northern Bukovina. Italy and Germany, which needed a stable Romania and access to its oil fields urged
King Carol II to do so. Under duress, with no prospect of aid from France or Britain, Carol complied. On 28 June, Soviet troops crossed the Dniester and
occupied Bessarabia,
Northern Bukovina, and the
Hertsa region.
Great Patriotic War On 22 June 1941,
Adolf Hitler abruptly broke the non-aggression pact and
invaded the Soviet Union. Stalin had made no preparations. Soviet intelligence was fooled by German disinformation and the invasion caught the Soviet military unprepared. In the larger sense, Stalin expected invasion but not so soon. The Army had been decimated by the Purges; time was needed for a recovery of competence. As such, mobilization did not occur and the Soviet Army was tactically unprepared as of the invasion. The initial weeks of the war were a disaster, with hundreds of thousands of men being killed, wounded, or captured. Whole divisions disintegrated against the German onslaught. Soviet POWs in German prison camps were treated poorly, leading to only 1/10 of Red Army POWs surviving German camps. In contrast, 1/3 of German POWs survived the Soviet prison camps. German troops reached the outskirts of Moscow in December 1941, but failed to capture it, due to staunch Soviet defence and counterattacks. At the
Battle of Stalingrad in 1942–1943, the Red Army inflicted a crushing defeat on the German army. Due to the unwillingness of the Japanese to open a second front in
Manchuria, the Soviets were able to call dozens of Red Army divisions back from eastern Russia. These units were instrumental in turning the tide, because most of their officer corps had escaped Stalin's purges. The Soviet forces soon launched massive counterattacks along the entire German line. By 1944, the Germans had been pushed out of the Soviet Union onto the banks of the
Vistula river, just east of Prussia. With Soviet Marshal
Georgy Zhukov attacking from Prussia, and Marshal
Ivan Konev slicing Germany in half from the south, the fate of
Nazi Germany was sealed. On 2 May 1945 the last German troops surrendered to the Soviet troops in Berlin. " photo, taken to symbolize the Soviet victory at the
Battle of Berlin Wartime developments From the end of 1944 to 1949, large sections of eastern Germany came under the Soviet Union's occupation and on 2 May 1945,
the capital city Berlin was taken, while over fifteen million Germans were removed from eastern Germany (renamed the
Recovered Territories of the
Polish People's Republic) and pushed into
central Germany (later called the
German Democratic Republic) and
western Germany (later called the
Federal Republic of Germany). An atmosphere of
patriotic emergency took over the Soviet Union during the war, and persecution of the Orthodox Church was halted. The Church was now permitted to operate with a fair degree of freedom, so long as it did not get involved in politics. In 1944, a
new Soviet national anthem was written, replacing
the Internationale, which had been used as the national anthem since 1918. These changes were made because it was thought that the people would respond better to a fight for their country than for a political ideology. The Soviets bore the brunt of World War II because the West did not open up a second ground front in Europe until the
invasion of Italy and the
Battle of Normandy. Approximately 26.6 million Soviets, among them 18 million civilians, were killed in the war. Civilians were rounded up and burned or shot in many cities conquered by the Nazis. The retreating Soviet army was ordered to pursue a '
scorched earth' policy whereby retreating Soviet troops were ordered to destroy civilian infrastructure and food supplies so that the Nazi German troops could not use them. Stalin's original declaration in March 1946 that there were 7 million war dead was revised in 1956 by
Nikita Khrushchev with a round number of 20 million. In the late 1980s, demographers in the State Statistics Committee (
Goskomstat) took another look using demographic methods and came up with an estimate of 26–27 million. A variety of other estimates have been made. In most detailed estimates roughly two-thirds of the estimated deaths were civilian losses. However, the breakdown of war losses by nationality is less well known. One study, relying on indirect evidence from the 1959 population census, found that while in terms of the aggregate human losses the major Slavic groups suffered most, the largest losses relative to population size were incurred by minority nationalities mainly from European Russia, among groups from which men were mustered to the front in "nationality battalions" and appear to have suffered disproportionately. After the war, the Soviet Union
occupied and dominated Eastern Europe, in line with
Soviet ideology. Stalin was determined to punish those peoples he saw as
collaborating with Germany during the war and to deal with the problem of
nationalism, which would tend to pull the Soviet Union apart. Millions of Poles, Latvians, Georgians, Ukrainians and other ethnic minorities were deported to Gulags in Siberia. (Previously, following
the 1939 annexation of eastern Poland, thousands of Polish Army officers, including reservists, had been executed in the spring of 1940, in what came to be known as the
Katyn massacre.) In addition, in 1941, 1943 and 1944 several whole nationalities had been deported to Siberia, Kazakhstan, and Central Asia, including, among others, the
Volga Germans,
Chechens,
Ingush,
Balkars,
Crimean Tatars, and
Meskhetian Turks. Though these groups were later politically "rehabilitated", some were never given back their former autonomous regions. At the same time, in a famous
Victory Day toast in May 1945, Stalin extolled the role of the
Russian people in the defeat of the fascists. World War II resulted in enormous destruction of infrastructure and populations throughout
Eurasia, from the Atlantic to the Pacific oceans, with almost no country left unscathed. The Soviet Union was especially devastated due to the mass destruction of the industrial base that it had built up in the 1930s. The USSR also experienced a major
famine in 1946–1948 due to war devastation that cost an estimated 1 to 1.5 million lives as well as secondary population losses due to reduced fertility. However, the Soviet Union recovered its production capabilities and overcame pre-war capabilities, becoming the country with the most powerful land army in history by the end of the war, and having the most powerful military production capabilities.
War and Stalinist industrial-military development Although the Soviet Union received aid and weapons from the United States under the
Lend-Lease program, the Soviet production of war materials was greater than that of Nazi Germany because of rapid growth of Soviet industrial production during the interwar years (additional supplies from lend-lease accounted for about 10–12% of the Soviet Union's own industrial output). The Second Five Year Plan raised
steel production to 18 million tons and
coal to 128 million tons. Before it was interrupted, the
Third Five Year Plan produced no less than 19 million tons of steel and 150 million tons of coal. The Soviet Union's industrial output provided an armaments industry which supported their army, helping it resist the Nazi military offensive. According to Robert L. Hutchings, "One can hardly doubt that if there had been a slower buildup of industry, the attack would have been successful and world history would have evolved quite differently." For the laborers involved in industry, however, life was difficult. Workers were encouraged to fulfill and overachieve quotas through
propaganda, such as the
Stakhanovite movement. Some historians, however, interpret the lack of preparedness of the Soviet Union to defend itself as a flaw in Stalin's economic planning. David Shearer, for example, argues that there was "a command-administrative economy" but it was not "a planned one". He argues that the Soviet Union was still suffering from the Great Purge, and was completely unprepared for the German invasion. Economist Holland Hunter, in addition, argues in his
Overambitious First Soviet Five-Year Plan, that an array "of alternative paths were available, evolving out of the situation existing at the end of the 1920s... that could have been as good as those achieved by, say, 1936 yet with far less turbulence, waste, destruction and sacrifice." ==Cold War==
