The Curzon Line and territorial changes to Poland, 1939 to 1945
After the
Soviet invasion of Poland following the corresponding
German invasion that marked the start of
World War II in 1939, the
Soviet Union annexed eastern parts (so-called "''
Kresy''") of the
Second Polish Republic, totaling 201,015 km² and a population of 13.299 million. Most of those territories became part of the Soviet Union in 1945 as part of the
Europe-wide territorial rearrangement caused by the
World War II. Poland was partially compensated by the Soviet Union with former German territories, the so called "''
Recovered Territories''".
Soviet Occupation 1939-1941
Under the terms of the
Molotov-Ribbentrop Pact, adjusted by agreement on
28 September 1939, the
Soviet Union annexed all
Polish territory east of the line of the rivers
Pisa,
Narew,
Western Bug, and
San, except for
Wilno Voivodship with its capital Wilno (
Vilnius), which was given to
Lithuania, and the
Suwałki region, which was annexed by
Nazi Germany. Initially captured by Poland in a series of wars between 1918 and 1921 (primarily the
Polish-Soviet War), these territories had mixed population of different nationalities with
Poles and
Ukrainians being the most numerous ethnic groups, as well as large minorities of
Belarusians and
Jews.
[1] However, as the different national groups were located in a patchwork of mixed settlement patterns, much of the territory had its own significant local non-Polish majority (Ukrainians in the south and Belarusians in the North), especially in the rural areas.
["Ukrainians made up a clear majority in the total population of Stanisławów, Tarnopol, and Lwów Voivodships constituting Eastern Galicia. Add the coniguous territory of Wolyn Voivodship (70 percent Ukrainian) and the Ukrainian majority in the area becomes overwhelming... The eastern half of Poland could be divided into three zones north to south. A clear Ukrainian majority resided in the south, except in some areas where Poles more or less equaled their Ukrainian neighbors; in the central part, in Polesie and Wołyń, a small Polish minority (14 and 16 percent respectively) faced a mostly Orthodox peasantry (Ukrainian to the south, then "local" and finally, on the northern fringe increasingly Belarusian); and in the northern part, in Białystok, Wilno and Nowogródek voivodships, Poles were in majority, confronted by a numerically strong Belarusian minority. Jews constituted the principal counterpart of the Poles in Urban areas"]
Jan Tomasz Gross, ''Revolution from Abroad'', pp. 4, 5, Princeton, 2005, ISBN 0-691-09603-1 (Google books link) The "need to protect" the Ukrainian and Belarusian population was used as a pretext for Soviet invasion of Eastern Poland (including Western Ukraine and Belarus) carried out in the wake of Poland's falling apart under the Nazi invasion with Warsaw being besieged and Poland's government being in the process of evacuation.
[2] The total area, including the area given to Lithuania, was 201,015 square kilometres, with a population of 13.299 million, of which 5.274 million were ethnic Poles and 1.109 million were Jews.
[ Concise statistical year-book of Poland , Polish Ministry of Information. London June 1941 P.9 & 10 ]An additional 138,000 ethnic Poles and 198,000 Jews fled the German occupied zone and became refugees in the Soviet occupied region
[ Poland's Holocaust, Tadeusz Piotrowski,1998 ISBN 0-7864-0371-3 P.14]
During 1939-1941 1.450 million.of the people inhabiting the region were deported by the Soviet regime, of whom 63.1% were Poles, and 7.4% were Jews.
[ Poland's Holocaust, Tadeusz Piotrowski, 1998 ISBN 0-7864-0371-3, P.14] Previously it was believed that about 1.0 million Polish citizens died at the hands of the Soviets,
[Franciszek Proch, Poland's Way of the Cross, New York 1987 P.146] however recently Polish historians, based mostly on queries in Soviet archives, estimate the number of deaths at about 350,000 people deported in 1939-1945.
[Project In Posterum [2](go to note on Polish Casualties by Tadeusz Piotrowski)]
Polish northern territories, around
Wilno, were annexed by
Lithuania (and soon afterwards, Lithuania was annexed by Soviet Union and became the
Lithuanian SSR). Other northern territories were attached to
Belastok Voblast,
Hrodna Voblast,
Navahrudak Voblast (soon renamed to
Baranavichy Voblast),
Pinsk Voblast and
Vileyka (later Maladzyechna) Voblast in
Byelorussian SSR.
Ukrainian SSR divided the territories in the south it received from Poland's annexation into:
Lviv Oblast,
Rivne Oblast,
Stanislav (later known as Ivano-Frankivsk) Oblast,
Tarnopil Oblast and
Volyn Oblast,
German Occupation 1941-1944
These areas were conquered by the
Nazi Germany in
1941 during
Operation Barbarossa. The Nazis divided them up as follows:
★ ''
Bezirk Bialystok'' (district of
Białystok), which included the Białystok,
Bielsk Podlaski,
Grajewo,
Åomża,
Sokółka,
Vaukavysk, and
Hrodna counties and was "attached to" (not incorporated into)
East Prussia;
★ ''
Bezirk Litauen und Weissruthenien'' — the Polish parts of White Ruthenia (today western
Belarus), including the
Vilnius (Vilna) province of
Lithuania, which was incorporated into the
Reichskommissariat Ostland;
★ ''
Bezirk Wolhynien-Podolien'' — the Polish province of
Volhynia, which was incorporated into the
Reichskommissariat Ukraine; and
★ ''
District Galicia'', East
Galicia, which was incorporated into the
General Government and became its fifth district.
During 1943-1944 the
Massacres of Poles in Volhynia caused about 100,000 deaths and the mass exdous of Poles from the Ukraine.
The Polish and Jewish language population of the annexed regions totaled about 6.7 million in 1939. During the war 2 million perished (including 1.2 million Jews) and are included with Polish war losses, 2 million (including 250,000 Jews) became refugees in Poland or the west, 1.5 million were in the territories given back to Poland in 1945 and
1.2 million remained in the USSR.
[3] Contemporary Russian historians also include the war losses of Poles and Jews from this region with Soviet war dead.

Soviet Annexation 1945
After the end of
World War II, the Soviet Union kept most of the territories occupied in 1939, while territories with an area of 21,275 square kilometers with 1.5 million inhabitants were returned to its Polish ally, notably the areas near
Białystok and
Przemyśl.
[" U.S. Bureau of the Census ''The Population of Poland'' Ed. W. Parker Mauldin, Washington- 1954 P.140]
On August 16, 1945 the communist dominated Polish government signed a treaty with the USSR to formaly cede these territories.The total population of the territories annexed by the USSR, not including the portion returned to Poland in 1945, had a population of 10,653,000 according to the 1931 Polish census. In 1939 this had increased to about 11.6 million. The composition by language group was
Ukrainian 37.1%,
Belarusian 15.1%, Polish 36.5%,
Yiddish 8.3%, Other 3%. Religious affiliation:
Russian Orthodox 31.6%,
Ukrainian Greek Catholic Church 26.7%
Roman Catholic 30.1%, Jewish 9.9%, Other 1.7%.
[" U.S. Bureau of the Census ''The Population of Poland'' Ed. W. Parker Mauldin, Washington- 1954 P.148-149]
From 1944 until 1952 the
Ukrainian Insurgent Army continued an armed struggle against the communists. The Soviets deported 600,000 people from these territories and 170,000 of the local population were killed in the fighting (See also
Akcja Wisła).

''...the Soviet Government intended to motivate its procedure as follows: the Polish State had collapsed and no longer existed; therefore all agreements concluded with Poland were void; third powers might try to profit by the chaos which had arisen; the Soviet Union considered itself obligated to intervene to protect its Ukrainian and White Russian brothers and make it possible for these unfortunate people to work in peace.(...) Molotov conceded that the projected argument of the Soviet Government contained a note that was jarring to German sensibilities but asked that in view of the difficult situation of the Soviet Government we not let a trifle like this stand in our way. The Soviet Government unfortunately saw no possibility of any other motivation, since the Soviet Union had thus far not concerned itself about the plight of its minorities in Poland and had to justify abroad, in some way or other, its present intervention.
