What significant territorial changes occurred in Poland following the German invasion in 1939?

Seventeen days after Nazi Germany's invasion of Poland in 1939, which initiated World War II, the Soviet Union entered the eastern regions of Poland, known as the Kresy. The Soviets annexed territories covering 201,015 square kilometers (77,612 sq mi) with a population of 13,299,000.

Who were the primary ethnic groups residing in the Polish territories annexed by the Soviet Union in 1939?

The population in the annexed territories included ethnic Poles, along with significant Belarusian and Ukrainian majorities. Other minority groups present were Czechs, Lithuanians, and Jews.

How were the Soviet-annexed territories of Poland incorporated into the Soviet Union after 1939?

These annexed territories were subsequently integrated into the Lithuanian, Byelorussian, and Ukrainian Soviet Socialist Republics. They remained part of the Soviet Union following the territorial rearrangements established during the Tehran Conference in 1943.

What was Poland's territorial compensation for the loss of its eastern regions to the Soviet Union?

Poland was compensated for the loss of its eastern territories by gaining pre-War German eastern territories. This redistribution occurred at the expense of Poland's original eastern regions.

What term did the Polish People's Republic use to describe the territories lost to the Soviet Union?

The regime of the Polish People's Republic referred to these territories as the "Recovered Territories." This term reflected a post-war perspective on territorial adjustments.

What was the estimated population of Poles in the Kresy region in 1939, and how did it change due to conflict and displacement?

In 1939, the Kresy region had approximately 5.274 million ethnic Poles. Following ethnic cleansing and conflict involving Nazi Germany, the Soviet Union, and Ukrainian nationalist forces between 1939 and 1945, the population of the Kresy was reduced to about 1.8 million inhabitants.

How did the territory of Poland change in size after World War II compared to its pre-1939 borders?

After World War II, Poland's territory was slightly smaller than its pre-1939 land area. It shrank by approximately 77,000 square kilometers (30,000 sq mi), a loss roughly equivalent to the combined size of Belgium and the Netherlands.

What was the Molotov–Ribbentrop Pact, and when was it signed?

The Molotov–Ribbentrop Pact was a 10-year non-aggression treaty signed between the Soviet Union and Nazi Germany in the early morning of August 24, 1939. It was a significant diplomatic agreement preceding the outbreak of World War II.

What was the significance of the secret protocol within the Molotov–Ribbentrop Pact?

The pact contained a secret protocol, which was only revealed after Germany's defeat in 1945. This protocol divided Northern and Eastern European countries into German and Soviet "spheres of influence."

Which Northern European countries were assigned to the Soviet sphere of influence according to the secret protocol?

According to the secret protocol of the Molotov–Ribbentrop Pact, Finland, Estonia, and Latvia were designated for the Soviet sphere of influence.

How did the Molotov–Ribbentrop Pact plan to partition Poland?

The pact stipulated that Poland would be partitioned in the event of its "political rearrangement." The territories east of the Narev, Vistula, and San Rivers were designated for the Soviet Union, while Germany would occupy the western parts.

What was the historical context of the territories east of the Narev, Vistula, and San Rivers prior to the Molotov–Ribbentrop Pact?

These territories had been annexed by Poland in a series of wars between 1918 and 1921, most notably the Polish-Soviet War. They were characterized by mixed urban national populations, with Poles and Ukrainians being the most numerous, alongside significant Belarusian and Jewish minorities.

How was Lithuania initially positioned within the Molotov–Ribbentrop Pact's secret protocols regarding spheres of influence?

Initially, Lithuania was placed within the German sphere of influence due to its proximity to East Prussia. However, a subsequent secret protocol agreed upon in September 1939 reassigned the majority of Lithuania to the USSR.

What promise was made to Lithuania concerning its historical capital in the second secret protocol of the Molotov–Ribbentrop Pact?

The second secret protocol of the Molotov–Ribbentrop Pact stipulated that Lithuania would regain its historical capital, Vilnius. Vilnius had been under Polish control during the inter-war period.

When did the Soviet Union invade the eastern parts of Poland as per the Molotov–Ribbentrop Pact?

The Soviet Union invaded the eastern portions of Poland assigned to it by the Pact approximately two weeks after the German invasion of western Poland, coordinating its actions with German forces.

What justification did the Soviet Union provide for its invasion of Eastern Poland in 1939?

The Soviet Union cited a "need to protect" the Ukrainian and Belarusian populations residing in these regions as justification for its invasion. This occurred amidst Poland's dismemberment by the Nazi invasion and the siege of Warsaw.

How did some minority populations in Eastern Poland react to the arrival of Soviet troops in 1939?

Many Ukrainians, Belarusians, and Jews in the occupied territories welcomed the Soviet troops. This reception was partly influenced by the oppressive Polonization programs previously carried out by the Second Polish Republic against these minorities.

What was the total area and population of the territories annexed by the Soviet Union, including the portion initially assigned to Lithuania?

The total area annexed by the Soviet Union, including the region given to Lithuania, was 201,015 square kilometers (77,612 sq mi). The population in this area was approximately 13.299 million, comprising 5.274 million ethnic Poles and 1.109 million Jews.

An additional 138,000 ethnic Poles and 198,000 Jews fled the German-occupied zone and became refugees in the Soviet-occupied region following the initial invasions.

What was the immediate policy implemented by Soviet authorities in the newly acquired territories?

Soviet authorities immediately initiated a campaign of "sovietization." This involved measures such as passportization and residence registration of the population in the newly acquired territories.

How did the Soviet authorities use the passportization process?

The NKVD utilized the passportization system to meticulously identify and select individuals residing in Western Belarus and Western Ukraine. Those who did not receive Soviet citizenship or refused it, often asserting their Polish citizenship or rejecting Ukrainian or Belarusian nationality, faced arrest or deportation.

What happened to refugees from western Poland who were in Kresy after September 1939?

In March 1940, Soviet authorities decided on the fate of refugees from western Poland who had been in Kresy since September 1939. A deportation of approximately 75,000 to 80,000 people, predominantly Jews (about 84%), began on June 29, 1940, and continued for nearly a month.

What actions did Soviet authorities take to legitimize their annexation of eastern Poland?

Soviet authorities organized staged elections in the annexed territories. The results of these elections were intended to serve as a form of legitimization for the Soviet annexation of eastern Poland.

What measures did the Soviet Union implement to erase Polish history and culture in the annexed territories?

Soviet authorities attempted to erase Polish history and culture by withdrawing the Polish currency without exchanging it for rubles, collectivizing agriculture, and nationalizing and redistributing private and state-owned Polish property.

How did the Soviets view service to the pre-war Polish state in the annexed territories?

Soviet authorities considered service to the pre-war Polish state as a "crime against revolution" and "counter-revolutionary activity." This classification led to the arrest of large numbers of Polish citizens.

What was the estimated number of Poles taken prisoner by the Soviets during the initial invasion of Poland?

Between 230,000 and 450,000 Poles were taken prisoner by the Soviet Union during the initial invasion of Poland. Some of these prisoners were subsequently executed.

What event resulted from a March 5, 1940, order signed by Lavrenty Beria concerning Polish POWs?

On March 5, 1940, pursuant to a note from Lavrenty Beria, the Soviet Politburo, including Stalin, signed an order to execute Polish prisoners of war held in camps and prisons in occupied western Ukraine and Belarus. These individuals were labeled "nationalists and counterrevolutionaries." This event is known as the Katyn massacre, in which approximately 22,000 people were executed.

What were the differing claims regarding the fate of Polish officers executed in the Katyn massacre?

During Perestroika, former Stalinist ministers like Lazar Kaganovich and Vyacheslav Molotov claimed that while the NKVD killed roughly 3,000 Polish officers in 1940, the remaining executed officers were killed by the Nazis later. However, the established historical consensus points to Soviet responsibility for the entire massacre.

How have estimates of Polish deaths due to Soviet actions evolved, according to recent historical research?

Previously, it was believed that about one million Polish citizens died at the hands of the Soviets. However, recent research by Polish historians, based on Soviet archives, estimates the number of deaths among those deported between 1939 and 1945 at about 350,000 people.

How did the Nazis administer the Polish territories they conquered in 1941 during Operation Barbarossa?

The Nazis divided the conquered territories into several administrative units: Bezirk Białystok (attached to East Prussia), Generalbezirk Litauen (Vilna Province incorporated into Lithuania and Reichskommissariat Ostland), Generalbezirk Weißruthenien (western Belarus incorporated into Reichskommissariat Ostland), Generalbezirk Wolhynien und Podolien (Volhynia and Polesie incorporated into Reichskommissariat Ukraine), and District Galicia (East Galicia incorporated into the General Government).

What significant ethnic conflict occurred in Ukraine between 1943 and 1944 within these occupied territories?

Between 1943 and 1944, ethnic cleansing operations, commonly known as the Massacres of Poles in Volhynia, took place in Ukraine. These operations resulted in an estimated 100,000 deaths and led to an exodus of ethnic Poles from the territory.

What were the estimated war-related losses for the Polish and Jewish populations in the annexed regions during World War II?

What was the outcome of the Yalta Conference regarding the territories annexed by the Soviet Union?

At the Yalta Conference, an agreement was reached where the Soviets would annex the entirety of their Molotov–Ribbentrop Pact portion of Eastern Poland. In return, Poland was to be granted part of Eastern Germany. Western Allies were reportedly unaware of the 1939 secret clause that had already divided Poland.

Were any parts of the territories annexed by the Soviet Union in 1939 returned to postwar Poland?

Yes, some parts of eastern Poland occupied by the Soviet Union in 1939 were returned to postwar Poland. These areas, totaling 21,275 square kilometers (8,214 sq mi) with 1.5 million inhabitants, were located near Białystok and Przemyśl.

When was the treaty signed that formally ceded the annexed territories to the USSR, and by whom?

Historical Context: Annexation Overview

Territorial Scope

Following the German invasion of Poland in 1939, the Soviet Union entered the eastern regions of Poland, known historically as the Kresy. This action resulted in the annexation of territories totaling 201,015 square kilometers (approximately 77,612 square miles). This significant territorial acquisition profoundly altered the geopolitical landscape of Eastern Europe.

Demographic Composition

The annexed territories were inhabited by a diverse population. While ethnic Poles constituted a substantial portion, significant communities of Belarusians and Ukrainians formed the majority. Additionally, smaller groups including Czechs, Lithuanians, and Jews resided in these regions, contributing to the complex ethnic mosaic of the area prior to Soviet control.

Incorporation into Soviet Republics

These annexed lands were subsequently integrated into the Soviet Union's administrative structure. Specifically, they were incorporated into the Lithuanian, Byelorussian, and Ukrainian Soviet Socialist Republics. This formal incorporation marked the beginning of a period of Sovietization and political restructuring.

The Molotov-Ribbentrop Pact

A Non-Aggression Agreement

On August 23, 1939, the Soviet Union and Nazi Germany signed a 10-year non-aggression pact, commonly known as the Molotov-Ribbentrop Pact. This agreement, while ostensibly a pact of non-aggression, contained a clandestine protocol that fundamentally reshaped the map of Eastern Europe.

Secret Protocol and Spheres of Influence

The secret protocol, revealed only after World War II, delineated spheres of influence for both powers. Northern and Eastern European states were divided. Poland was designated for partition along the Narev, Vistula, and San Rivers, with territories east of these lines assigned to the Soviet sphere and the west to Germany, contingent upon Poland's "political rearrangement." Lithuania was initially assigned to the German sphere but later allocated to the USSR in a revised protocol.

Soviet Invasion and Annexation (1939-1941)

The Invasion

Seventeen days after the German invasion commenced, on September 17, 1939, the Soviet Union invaded the eastern regions of Poland. This action was justified by Soviet authorities as a measure to "protect" the Ukrainian and Belarusian populations, occurring as Warsaw was besieged and the Polish government was evacuating.

Sovietization and Repression

Upon taking control, Soviet authorities initiated a campaign of Sovietization. This involved implementing a passport system to identify and categorize the population, leading to the arrest or deportation of those who did not accept Soviet citizenship or refused to align with the new regime. Polish currency was withdrawn, private property nationalized, and agriculture collectivized. Service to the pre-war Polish state was deemed a "crime against revolution."

The Katyn Massacre

A particularly grim consequence of the Soviet occupation was the Katyn massacre. In March 1940, pursuant to an order signed by members of the Soviet Politburo, including Stalin, approximately 22,000 Polish prisoners of war, identified as "nationalists and counterrevolutionaries," were executed by the NKVD. This event remains a deeply sensitive and significant historical tragedy.

Population Displacement

Between 1939 and 1941, the Soviet regime deported an estimated 1.45 million inhabitants from the annexed territories. Poles constituted the majority of these deportees (63.1%), with Jews making up 7.4%. Later estimates suggest that between 1939 and 1945, approximately 350,000 people deported from these regions perished. An additional 138,000 Poles and 198,000 Jews fled from German-occupied zones into the Soviet-controlled areas.

German Occupation (1941-1944)

Nazi Administration

In 1941, Nazi Germany conquered these Soviet-occupied territories during Operation Barbarossa. The region was administratively divided by the Nazis into several districts, including Bezirk Białystok (attached to East Prussia), Generalbezirk Litauen, Generalbezirk Weißruthenien, Generalbezirk Wolhynien und Podolien, and District Galicia (incorporated into the General Government). This period was marked by brutal occupation policies and ethnic cleansing operations, notably the Massacres of Poles in Volhynia.

Soviet Re-annexation and Post-War Rearrangements (1945)

Allied Conferences and Decisions

By the end of World War II, the Soviet Union re-entered Poland and re-annexed most of the territories it had occupied in 1939. These territorial changes were largely confirmed and consolidated at the Yalta Conference (1945) and the Potsdam Conference (1945). The Western Allies were largely unaware of the 1939 secret protocol that had initially divided Poland.

Final Incorporation

Following the war, the eastern territories of pre-war Poland were formally annexed into the Ukrainian Soviet Socialist Republic and the Byelorussian Soviet Socialist Republic. This arrangement represented a significant shift in Poland's post-war borders, compensated by territorial gains in the west from former German territories.

Formal Border Treaty and Demographics

August 1945 Agreement

On August 16, 1945, the Provisional Government of National Unity, dominated by communists, signed a treaty with the USSR formally ceding these territories. Some areas totaling 21,275 square kilometers (8,214 sq mi) near Białystok and Przemyśl, with approximately 1.5 million inhabitants, were returned to post-war Poland.

Population Statistics (1931 Census)

The total population of the territories annexed by the USSR (excluding those returned to Poland in 1945) was estimated at 10,653,000 according to the 1931 Polish census, rising to about 11.6 million by 1939. The linguistic breakdown was approximately: Ukrainian 37.1%, Polish 36.5%, Belarusian 15.1%, Yiddish 8.3%, and Other 3%. Religious affiliations included Eastern Orthodox (31.6%), Roman Catholic (30.1%), Ukrainian Greek Catholic (26.7%), and Jewish (9.9%).

Subsequent Developments

Post-War Conflicts and Realignment

From 1944 to 1952, the Ukrainian Insurgent Army (UIA) engaged in armed conflict against Soviet forces in these territories, leading to deportations of 600,000 people and an estimated 170,000 local deaths. Additionally, between 1945 and 1947, Red Army soldiers committed acts of violence against the civilian population in the territories later known as Poland's "Recovered Territories." The Soviet-Polish border was further realigned in two areas in June 1951.
