Red Army in the context of "Polish People's Republic"

Crimea in the five years after the Russian Revolution had a large number of governments culminating in being a stronghold of anti-Communist forces and the place on Russian soil where they made their last stand.

Following the Russian Revolution of 1917, the military and political situation in Crimea was chaotic like that in much of Russia. During the ensuing Russian Civil War, Crimea changed hands numerous times and was for a time a stronghold of the anti-Bolshevik White Army. It was in Crimea that the White Russians led by General Wrangel made their last stand against Nestor Makhno and the Red Army in 1920. When resistance was crushed, many of the anti-Bolshevik fighters and civilians escaped by ship to Istanbul.

The deportation of the Crimean Tatars (Crimean Tatar: Qırımtatar halqınıñ sürgünligi, Cyrillic: Къырымтатар халкъынынъ сюргюнлиги) or the Sürgünlik ('exile') was the ethnic cleansing and the cultural genocide of at least 191,044 Crimean Tatars that was carried out by Soviet Union authorities from 18 to 20 May 1944, supervised by Lavrentiy Beria, chief of Soviet state security and the secret police, and ordered by the Soviet leader Joseph Stalin. Within those three days, the NKVD used cattle trains to deport the Crimean Tatars, even Soviet Communist Party members and Red Army soldiers, from Crimea to the Uzbek SSR, several thousand kilometres away. They were one of several ethnicities that were subjected to Stalin's policy of population transfer in the Soviet Union.

Officially, the Soviet government presented the deportation as a policy of collective punishment, based on its claim that some Crimean Tatars collaborated with Nazi Germany in World War II, despite the fact that the 20,000 who collaborated with the Axis powers were half the 40,000 who served in the Soviet Red Army. Several modern scholars believe rather that the government deported them as a part of its plan to gain access to the Dardanelles and acquire territory in Turkey, where the Turkic ethnic kin of the Tatars lived, or remove minorities from the Soviet Union's border regions. By the end of the deportation, not a single Crimean Tatar lived in Crimea, and 80,000 houses and 360,000 acres of land were left abandoned. Nearly 8,000 Crimean Tatars died during the deportation, and tens of thousands subsequently perished due to the harsh living conditions in which they were forced to live during their exile. After the deportation, the Soviet government launched an intense detatarization campaign in an attempt to erase the remaining traces of Crimean Tatar existence.

Acceptance in psychology is a person's recognition and assent to the finality of a situation without attempting to change or protest it. This plays out at both the individual and societal level as people experience change.

World War II was the deadliest military conflict in history. An estimated total of 70–85 million deaths were caused by the conflict, representing about 3% of the estimated global population of 2.3 billion in 1940. Deaths directly caused by the war (including military and civilian fatalities) are estimated at 50–56 million, with an additional estimated 19–28 million deaths from war-related disease and famine. Civilian deaths totaled 50–55 million. Military deaths from all causes totaled 21–25 million, including deaths in captivity of about 5 million prisoners of war. More than half of the total number of casualties are accounted for by the dead of the Republic of China and of the Soviet Union. The following tables give a detailed country-by-country count of human losses.

Recent historical scholarship has shed new light on the topic of Second World War casualties. Research in Russia since the collapse of the Soviet Union has caused a revision of estimates of Soviet World War II fatalities. According to Russian government figures, USSR losses within postwar borders now stand at 26.6 million, including 8 to 9 million due to famine and disease. In August 2009 the Polish Institute of National Remembrance (IPN) researchers estimated Poland's dead at between 5.6 and 5.8 million. Historian Rüdiger Overmans of the Military History Research Office (Germany) published a study in 2000 estimating the German military dead and missing at 5.3 million, including 900,000 men conscripted from outside of Germany's 1937 borders, in Austria, and in east-central Europe. The Red Army claimed responsibility for the majority of Wehrmacht casualties during World War II. The People's Republic of China puts its war dead at 20 million, while the Japanese government puts its casualties due to the war at 3.1 million. An estimated 7–10 million people died in the Dutch, British, French and US colonies in South and Southeast Asia, mostly from war-related famine.

The Munich Agreement was reached in Munich on 30 September 1938, by Nazi Germany, the United Kingdom, France, and Italy. The agreement provided for the German annexation of part of Czechoslovakia called the Sudetenland, where three million people, mainly ethnic Germans, lived. The pact is known in some areas as the Munich Betrayal (Czech: Mnichovská zrada; Slovak: Mníchovská zrada), because of a previous 1924 alliance agreement and a 1925 military pact between France and the Czechoslovak Republic.

Germany had started a low-intensity undeclared war on Czechoslovakia on 17 September 1938. In reaction, Britain and France on 20 September formally requested Czechoslovakia cede the Sudetenland territory to Germany. This was followed by Polish and Hungarian territorial demands brought on 21 and 22 September, respectively. Meanwhile, German forces conquered parts of the Cheb District and Jeseník District, where battles included use of German artillery, Czechoslovak tanks, and armored vehicles. Lightly armed German infantry briefly overran other border counties before being repelled. Poland grouped its army units near its common border with Czechoslovakia and conducted an unsuccessful probing offensive on 23 September. Hungary moved its troops towards the border with Czechoslovakia, without attacking. The Soviet Union announced its willingness to come to Czechoslovakia's assistance, provided the Red Army would be able to cross Polish and Romanian territory; both countries refused.

The Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union, was a transcontinental country that spanned much of Eurasia from 1922 until it dissolved in 1991. During its existence, it was the largest country by area, extending across eleven time zones and sharing borders with twelve countries, and the third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of national republics, the largest and most populous of which was the Russian SFSR. In practice, its government and economy were highly centralized. As a one-party state governed by the Communist Party of the Soviet Union (CPSU), it was the flagship communist state. Its capital and largest city was Moscow.

The Soviet Union's roots lay in the October Revolution of 1917. The new government, led by Vladimir Lenin, established the Russian SFSR, the world's first constitutionally communist state. The revolution was not accepted by all within the Russian Republic, resulting in the Russian Civil War. The Russian SFSR and its subordinate republics were merged into the Soviet Union in 1922. Following Lenin's death in 1924, Joseph Stalin came to power, inaugurating rapid industrialization and forced collectivization that led to significant economic growth but contributed to a famine between 1930 and 1933 that killed millions. The Soviet forced labour camp system of the Gulag was expanded. During the late 1930s, Stalin's government conducted the Great Purge to remove opponents, resulting in large scale deportations, arrests, and show trials accompanied by public fear. Having failed to build an anti-Nazi coalition in Europe, the Soviet Union signed a non-aggression pact with Nazi Germany in 1939. Despite this, in 1941 Germany invaded the Soviet Union in the largest land invasion in history, opening the Eastern Front of World War II. The Soviets played a decisive role in defeating the Axis powers while liberating much of Central and Eastern Europe. However they would suffer an estimated 27 million casualties, which accounted for most losses among the victorious Allies. In the aftermath of the war, the Soviet Union consolidated the territory occupied by the Red Army, forming satellite states, and undertook rapid economic development which cemented its status as a superpower.

The Baltic states—Estonia, Latvia and Lithuania—were occupied and annexed by the Soviet Union in 1940 and remained under its control until its dissolution in 1991. For a period of several years during World War II, Nazi Germany occupied the Baltic states after it invaded the Soviet Union in 1941.

The initial Soviet invasion and occupation of the Baltic states began in June 1940 under the Molotov–Ribbentrop Pact, made between the Soviet Union and Nazi Germany in August 1939, before the outbreak of World War II. The three independent Baltic countries were annexed as constituent Republics of the Soviet Union in August 1940. Most Western countries did not recognise this annexation, and considered it illegal. In July 1941, the occupation of the Baltic states by Nazi Germany took place, just weeks after its invasion of the Soviet Union. The Third Reich incorporated them into its Reichskommissariat Ostland. In 1944, the Soviet Union recaptured most of the Baltic states as a result of the Red Army's Baltic Offensive, trapping the remaining German forces in the Courland Pocket until their formal surrender in May 1945.

Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and several of its European Axis allies starting on Sunday, 22 June 1941, during World War II. More than 3.8 million Axis troops invaded the western Soviet Union along a 2,900-kilometer (1,800 mi) front, with the main goal of capturing territory up to a line between Arkhangelsk and Astrakhan, known as the A–A line. The attack became the largest and costliest military offensive in human history, with around 10 million combatants taking part in the opening phase and over 8 million casualties by the end of the operation on 5 December 1941. It marked a major escalation of World War II, opened the Eastern Front—the largest and deadliest land war in history—and brought the Soviet Union into the Allied powers.

The operation, code-named after the Holy Roman Emperor Frederick Barbarossa ("red beard"), put into action Nazi Germany's ideological goals of eradicating communism and conquering the western Soviet Union to repopulate it with Germans under Generalplan Ost, which planned for the removal of the native Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. The material targets of the invasion were the agricultural and mineral resources of territories such as Ukraine and Byelorussia and oil fields in the Caucasus. The Axis eventually captured five million Soviet Red Army troops on the Eastern Front and deliberately starved to death or otherwise killed 3.3 million prisoners of war, as well as millions of civilians. Mass shootings and gassing operations, carried out by German paramilitary death squads and collaborators, murdered over a million Soviet Jews as part of the Holocaust.

The 1944 Romanian coup d'état, better known in Romanian historiography as the Act of 23 August (Romanian: Actul de la 23 august), was a coup d'état led by King Michael I of Romania during World War II on 23 August 1944. With the support of several political parties, the king removed the government of Ion Antonescu, which had aligned Romania with Nazi Germany, after the Axis front in northeastern Romania collapsed in the face of a successful Soviet offensive. The Romanian Army declared a unilateral ceasefire with the Soviet Red Army on the Moldavian front, an event viewed as decisive in the Allied advances against the Axis powers in the European theatre of World War II. The coup was supported by the Romanian Communist Party, the Social Democratic Party, the National Liberal Party, and the National Peasants' Party who had coalesced into the National Democratic Bloc in June 1944.

The Soviet occupation of Romania refers to the period from 1944 to August 1958, during which the Soviet Union maintained a significant military presence in Romania. The fate of the territories held by Romania after 1918 that were incorporated into the Soviet Union in 1940 is treated separately in the article on Soviet occupation of Bessarabia and Northern Bukovina.

During the Eastern Front offensive of 1944, the Soviet Army occupied the northwestern part of Moldavia as a result of armed combat that took place between the months of April and August of that year, while Romania was still an ally of Nazi Germany. The rest of the territory was occupied after Romania changed sides in World War II, as a result of the royal coup launched by King Michael I on August 23, 1944. On that date, the king announced that Romania had unilaterally ceased all military actions against the Allies, accepted the Allied armistice offer, and joined the war against the Axis powers. As no formal armistice offer had been extended yet, the Red Army occupied most of Romania as enemy territory prior to the signing of the Moscow Armistice of September 12, 1944.

The Russian Civil War (Russian: Гражданская война в России, romanized: Grazhdanskaya voyna v Rossii) was a multi-party civil war in the former Russian Empire sparked by the 1917 overthrowing of the Russian Provisional Government in the October Revolution, as many factions vied to determine Russia's political future. It resulted in the formation of the Russian Socialist Federative Soviet Republic and later the Soviet Union in most of its territory. Its finale marked the end of the Russian Revolution, which was one of the key events of the 20th century.

The Russian monarchy ended with the abdication of Tsar Nicholas II during the February Revolution, and Russia was in a state of political flux. A tense summer culminated in the October Revolution, where the Bolsheviks overthrew the provisional government of the new Russian Republic. Bolshevik seizure of power was not universally accepted, and the country descended into a conflict which became a full-scale civil war in May–June 1918. The two largest combatants were the Red Army, fighting for the establishment of a Bolshevik-led socialist state headed by Vladimir Lenin, and the forces known as the White movement (and its White Army), led mainly by the right-leaning officers of the Russian Empire, united around the figure of Alexander Kolchak. In addition, rival militant socialists, notably the Ukrainian anarchists of the Makhnovshchina and Left Socialist-Revolutionaries, were involved in conflict against the Bolsheviks. They, as well as non-ideological green armies, opposed the Bolsheviks, the Whites and the foreign interventionists. Thirteen foreign states intervened against the Red Army, notably the Allied intervention, whose primary goal was re-establishing the Eastern Front of World War I. Three foreign states of the Central Powers also intervened, rivaling the Allied intervention with the main goal of retaining the territory they had received in the Treaty of Brest-Litovsk with Soviet Russia.

The Battle of the Kerch Peninsula, which commenced with the Soviet Kerch-Feodosia Landing Operation (Russian: Керченско-Феодосийская десантная операция, romanized: Kerchensko-Feodosiyskaya desantnaya operatsiya) and ended with the German Operation Bustard Hunt (German: Unternehmen Trappenjagd), was a World War II battle between Erich von Manstein's German and Romanian 11th Army and the Soviet Crimean Front forces in the Kerch Peninsula, in the eastern part of the Crimean Peninsula. It began on 26 December 1941, with an amphibious landing operation by two Soviet armies intended to break the Siege of Sevastopol. Axis forces first contained the Soviet beachhead throughout the winter and interdicted its naval supply lines through aerial bombing. From January through April, the Crimean Front launched repeated offensives against the 11th Army, all of which failed with heavy losses. The Red Army lost 352,000 men in the attacks, while the Axis suffered 24,120 casualties. Superior German artillery firepower was largely responsible for the Soviet debacle.

On 8 May 1942, the Axis attacked in a major counteroffensive codenamed Trappenjagd which concluded by around 19 May 1942 with the defeat of the Soviet defending forces. Manstein used a large concentration of airpower, heavily armed infantry divisions, concentrated artillery bombardments and amphibious assaults to break through the Soviet front in its southern portion in 210 minutes, swing north with the 22nd Panzer Division to encircle the Soviet 51st Army on 10 May and annihilate it on 11 May. The remnants of the 44th and 47th armies were pursued to Kerch, where the last pockets of organized Soviet resistance were defeated by 19 May. The decisive element in the German victory was the campaign of airstrikes against the Crimean Front by Wolfram von Richthofen's 800 aircraft VIII. Fliegerkorps, which flew an average of 1,500 sorties per day in support of Trappenjagd and constantly attacked Soviet field positions, armored units, troop columns, medical evacuation ships, airfields, and supply lines. German bombers used up to 6,000 canisters of SD-2 anti-personnel cluster munitions to kill masses of fleeing Soviet infantrymen.

The Apostolic Autocephalous Orthodox Church of Georgia (Georgian: საქართველოს სამოციქულო ავტოკეფალური მართლმადიდებელი ეკლესია, romanized: sakartvelos samotsikulo avt'ok'epaluri martlmadidebeli ek'lesia), commonly known as the Georgian Orthodox Church or the Orthodox Church of Georgia, is an autocephalous Eastern Orthodox church in full communion with the other churches of Eastern Orthodoxy. It is Georgia's dominant religious institution, and a majority of Georgian people are members. The Orthodox Church of Georgia is one of the oldest churches in the world. It asserts apostolic foundation, and that its historical roots can be traced to the early and late Christianization of Iberia and Colchis by Andrew the Apostle in the 1st century AD and by Saint Nino in the 4th century AD, respectively. As in similar autocephalous Eastern Orthodox Christian churches, the church's highest governing body is the holy synod of bishops. The church is headed by the Patriarch of All Georgia, Ilia II, who was elected in 1977.

Eastern Orthodox Christianity was the state religion throughout most of Georgia's history until 1921, when the country, having declared independence from Russia in 1918, was occupied by the Red Army during the Soviet invasion of Georgia, becoming part of the Soviet Union. The current Constitution of Georgia recognizes the special role of the Georgian Orthodox Church in the country's history, but also stipulates the independence of the church from the state. Government relations are further defined and regulated by the Concordat of 2002.

The history of Poland from 1945 to 1989 spans the period of Marxist–Leninist regime in Poland after the end of World War II. These years, while featuring general industrialization, urbanization and many improvements in the standard of living, were marred by early Stalinist repressions, social unrest, political strife and severe economic difficulties.Near the end of World War II, the advancing Soviet Red Army, along with the Polish Armed Forces in the East, pushed out the Nazi German forces from occupied Poland. In February 1945, the Yalta Conference sanctioned the formation of a provisional government of Poland from a compromise coalition, until postwar elections. Joseph Stalin, the leader of the Soviet Union, manipulated the implementation of that ruling. A practically communist-controlled Provisional Government of National Unity was formed in Warsaw by ignoring the Polish government-in-exile based in London since 1940.

During the subsequent Potsdam Conference in July–August 1945, the three major Allies ratified a massive westerly shift of Poland's borders and approved its new territory between the Oder–Neisse line and the Curzon Line. The area of Poland was reduced in comparison to its pre-World War II extent and geographically resembled that of the medieval early Piast dynasty era. Following the destruction of the Polish-Jewish population in the Holocaust, the flight and expulsion of Germans in the west, resettlement of Ukrainians in the east, and the expulsion and resettlement of Poles from the Eastern Borderlands (Kresy), Poland became for the first time in its history an ethnically homogeneous nation-state without prominent minorities. The new government solidified its political power, while the Polish United Workers' Party (PZPR) under Bolesław Bierut gained firm control over the country, which would remain an independent state within the Soviet sphere of influence. The July Constitution was promulgated on 22 July 1952 and the country officially became the Polish People's Republic (PRL).

The Baltic Way (Lithuanian: Baltijos kelias; Latvian: Baltijas ceļš; Estonian: Balti kett) or Baltic Chain (also "Chain of Freedom") was a peaceful political demonstration that occurred on 23 August 1989. Approximately two million people joined their hands to form a human chain spanning 675 kilometres (419 mi) across the three Baltic states of Estonia, Latvia, and Lithuania, with a combined population of around eight million citizens, who had been subjected to the Soviet Union's occupation and communist repression for more than 45 years, precisely speaking, between the Soviet Union's re-occupation of the Baltic states in 1944 (which took place alongside Soviet Union's Red Army's counteroffensive towards the west during the final years of World War II) and the Singing Revolution (a series of Baltic independence movements between 1987 and 1991), which culminated in Estonia, Latvia, and Lithuania's independence, that was achieved just before the dissolution of the Soviet Union in 1991. The central government in Moscow considered the three Baltic countries constituent republics of the Soviet Union.

The demonstration originated from "Black Ribbon Day" protests held in Western cities in the 1980s. It marked the 50th anniversary of the Molotov–Ribbentrop Pact, in which Poland, Finland, Estonia, Latvia, Lithuania, and Romania were (as "spheres of influence") divided between the Soviet Union and Nazi Germany. The Soviet-Nazi pact led to the outbreak of World War II in September 1939 and the Soviet invasion and occupation of the Baltic countries in June 1940.

The Great Purge or Great Terror (Russian: Большой террор, romanized: Bol'shoy terror), also known as the Year of '37 (37-й год, Tridtsat' sed'moy god) and the Yezhovshchina (ежовщина [(j)ɪˈʐofɕːɪnə], lit. 'period of Yezhov'), was a political purge in the Soviet Union from 1936 to 1938. After the assassination of Sergei Kirov by Leonid Nikolaev in 1934, Joseph Stalin launched a series of show trials known as the Moscow trials to remove suspected dissenters from the Communist Party of the Soviet Union (especially those aligned with the Bolshevik party). The term "great purge" was popularized by historian Robert Conquest in his 1968 book, The Great Terror, whose title alluded to the French Revolution's Reign of Terror.

The purges were largely conducted by the NKVD (People's Commissariat for Internal Affairs), which functioned as the interior ministry and secret police of the USSR. In 1936, the NKVD under Genrikh Yagoda began the removal of the central party leadership, Old Bolsheviks, government officials, and regional party bosses. Soviet politicians who opposed or criticized Stalin were removed from office and imprisoned, or executed, by the NKVD. The purges were eventually expanded to the Red Army high command, which had a disastrous effect on the military. The campaigns also affected many other segments of society: the intelligentsia, wealthy peasants—especially those lending money or other wealth (kulaks)—and professionals. As the scope of the purge widened, the omnipresent suspicion of saboteurs and counter-revolutionaries (known collectively as wreckers) began affecting civilian life.

Nestor Ivanovych Makhno (Ukrainian: Нестор Іванович Махно, pronounced [ˈnɛstor iˈwɑnowɪtʃ mɐxˈnɔ]; 7 November 1888 – 25 July 1934), also known as Bat'ko Makhno (Ukrainian: Бáтько Махно́ [ˈbɑtʲko mɐxˈnɔ], lit. 'Father Makhno'), was a Ukrainian anarchist revolutionary and the commander of the Revolutionary Insurgent Army of Ukraine during the Ukrainian War of Independence. He established the Makhnovshchina (loosely translated as "Makhno movement"), a mass movement by the Ukrainian peasantry to establish anarchist communism in the country between 1918 and 1921. Initially centered around Makhno's home province of Katerynoslav and hometown of Huliaipole, it came to exert a strong influence over large areas of southern Ukraine, specifically in what is now the Zaporizhzhia Oblast of Ukraine.

Raised by a peasant family and coming of age amid the fervor around the 1905 Revolution, Makhno participated in a local anarchist group and spent seven years imprisoned for his involvement. With his release during the 1917 Revolution, Makhno became a local revolutionary leader in his hometown and oversaw the expropriation and redistribution of large estates to the peasantry. In the Ukrainian Civil War, Makhno sided with the Soviet Russian Bolsheviks against the Ukrainian nationalists and White movement, but his alliances with the Bolsheviks did not last. He rallied Bolshevik support to lead an insurgency, defeating the Central Powers' occupation forces at the Battle of Dibrivka and establishing the Makhnovshchina. Makhno's troops briefly integrated with the Bolshevik Red Army in the 1919 Soviet invasion of Ukraine, but split over differences on the movement's autonomy. Makhno rebuilt his army from the remains of Nykyfor Hryhoriv's forces in western Ukraine, routed the White Army at the Battle of Perehonivka, and captured most of southern and eastern Ukraine, where they again attempted to establish anarchist communism.

The Crimean campaign was conducted by the Axis as part of Operation Barbarossa during World War II. The invading force was led by Germany with support from Romania and Italy, while the Soviet Union took up defensive positions throughout the Crimean Peninsula. The Axis offensive routed the Red Army and enabled the three-year-long German occupation of Crimea.

Beginning on 26 September 1941, the German 11th Army and the Romanian Third Army and Fourth Army were involved in the fighting. They were opposed by the Soviet 51st Army and elements of the Black Sea Fleet. After the campaign, Crimea was occupied by Germany's Army Group A, with the 17th Army as a major subordinate formation.
