, the young post-war generation received education informing them that the boundaries of the People's Republic were the same as those on which the Polish nation had developed for centuries. Furthermore, they were instructed that the Polish "Motherland" has always been in the same location, even when "occupied" for long periods of time by foreigners or as political boundaries shifted.[Norman Davies, ''God's Playground: A History of Poland in Two Volumes'', 2005, p. 386, , ] The official view was that the Poles had always had the inalienable and inevitable right to inhabit the Recovered Territories, even if prevented from doing so by foreign powers. Furthermore, the Piast concept was used to persuade the Allied Powers, who found it difficult to define a Polish "ethnographic territory", to assume that it would be an intolerable injustice to not "give the territories back".
Because the Recovered Territories had been under German and Prussian rule for many centuries, many events of this history were perceived as part of "foreign" rather than "local" history in post-war Poland. Polish scholars thus concentrated on the Polish aspects of the territories: medieval Piast history of the region, the cultural, political and economic bonds to Poland, the history of the Polish-speaking population in Prussia and the "Drang nach Osten" as a historical constant since the Middle Ages.
By 1949, the term "Recovered Territories" had been dropped from Polish communist propaganda, but it is still used occasionally in common language.[Gregor Thum, ''Die fremde Stadt. Breslau nach 1945'', 2006, p. 298, , ] On the grounds that those areas should not be regarded as unique territories within the Polish state, the authorities began to refer to them instead as the "Western and Northern Lands".[Martin Åberg, Mikael Sandberg, ''Social Capital and Democratisation: Roots of Trust in Post-Communist Poland and Ukraine'', Ashgate Publishing, Ltd., 2003, ]

Wolff and Cordell say that along with the debunking of communist historiography, "the 'recovered territories' thesis ... has been discarded", and that "it is freely admitted in some circles that on the whole 'the recovered territories' had a wholly German character", but that this view has not necessarily been transmitted to the whole of Polish society.[Karl Cordell, Stefan Wolff (2005)]
''Germany's Foreign Policy Towards Poland and the Czech Republic: Ostpolitik Revisited''
. p. 139. , . "In addition ... it has been relatively easy for Polish historians and others to attempt to debunk communist historiography and present a more balanced analysis of the past – and not only with respect to Germany. It has been controversial, and often painful, but nevertheless it has been done. For example, Poland's acquisition in 1945 of eastern German territories is increasingly presented as the price Germany paid for launching a total war, and then having lost it totally. The 'recovered territories' thesis previously applied in almost equal measures by the communists and Catholic Church has been discarded. Some circles freely admit that on the whole, 'the recovered territories' in fact had a wholly German character. The extent to which this fact transmitted to groups other than the socially and politically engaged is a matter of debate." The term was also used outside Poland. In 1962, pope John XXIII

Origin of the post-war population according to 1950 census
During the Polish post-war census of December 1950, data about the pre-war places of residence of the inhabitants as of August 1939 was collected. In case of children born between September 1939 and December 1950, their place of residence was reported based on the pre-war places of residence of their mothers. Thanks to this data it is possible to reconstruct the pre-war geographical origin of the post-war population.

Millions of non-Poles – mainly Germans from the Recovered Territories, as well as some Ukrainians in the east – were to be expelled from the new Poland, while large numbers of Poles needed to be resettled having been expelled from the Kresy. The expellees were termed "repatriates". The result was the largest exchange of population in European history.

). The Polish government aimed to retain as many autochthons as possible, as their presence on former German territory was used to indicate the intrinsic "Polishness" of the area and justify its incorporation into the Polish state as "recovered" territories. "Verification" and "national rehabilitation" processes were set up to reveal a "dormant Polishness" and determine who was redeemable as a Polish citizen. Few were actually expelled.[Tomasz Kamusella in Prauser and Reeds (eds), ''The Expulsion of the German communities from Eastern Europe'', p.28, EUI HEC 2004/]
The "autochthons" not only disliked the subjective and often arbitrary verification process, but they also faced discrimination even after completing it, such as the Polonization of their names. In the Lubusz Voivodeship, Lubusz region (former East Brandenburg), the local authorities conceded already in 1948 that what the PZZ claimed to be a recovered "autochton" Polish population were in fact Germanized migrant workers, who had settled in the region in the late 19th and early 20th centuries – with the exception of one village, Babimost

Removal of Germans and traces of German habitation
The Communist authorities of the Polish People's Republic and some Polish citizens desired to erase all traces of German rule. The "Recovered Territories" after the transfer still contained a substantial German population. The Polish administration set up a "Ministry for the Recovered Territories", headed by the then deputy prime minister Władysław Gomułka

.[Karl Cordell, Andrzej Antoszewski, ''Poland and the European Union'', 2000, p.167, , ] A "Bureau for Repatriation" was to supervise and organize the expulsions and resettlements. According to the national census of 14 February 1946, the population of Poland still included 2,288,300 Germans, of which 2,036,439—nearly 89 per cent—lived in the ''Recovered Territories''. By this stage Germans still constituted more than 42 per cent of the inhabitants of these regions, since their total population according to the 1946 census was 4,822,075. However, by 1950 there were only 200,000 Germans remaining in Poland, and by 1957 that number fell to 65,000.
The flight and expulsion of the remaining Germans in the first post-war years presaged a broader campaign to remove signs of former German rule.[
More than 30,000 German placenames were replaced with Polish][Dan Diner, Raphael Gross, Yfaat Weiss, ''Jüdische Geschichte als allgemeine Geschichte'', p.164] or Polonized medieval Slavic ones.[Gregor Thum, ''Die fremde Stadt.

In January 1946, a Committee for Settling of Place Names was set up to assign new official toponyms. The German language was banned from public schools, government media and church services. Many German monuments, graveyards, buildings or entire ensembles of buildings were demolished. Objects of art were moved to other parts of the country. German inscriptions were erased, including those on religious objects, in churches and in cemeteries. In Ziemia Lubuska

"Socialist competitions" were organized to search and destroy final German traces.[
Historian John Kulczycki argues that the Communist authorities discovered that forging an ethnically homogeneous Poland in the Recovered Territories was quite complicated, for it was difficult to differentiate German speakers who were "really" Polish and those who were not. The government used criteria that involved explicit links to Polish ethnicity, as well the person's conduct. Local verification commissions had wide latitude in determining who was or was not Polish and should remain. Their decisions were based on the nationalist assumption that an individual's national identity is a lifetime "ascriptive" characteristic acquired at birth and not easily changed. However people who "betrayed" their Polish heritage by their political words or actions were excluded from the Polish nation. Everyone else was labelled as "Polish" and had to remain in their "native" land – even if they wanted to emigrate to Germany.

Operation Vistula ( pl, Akcja Wisła; uk, Опера́ція «Ві́сла») was a codename for the 1947 forced resettlement of 150,000 Ukrainians ( Boykos and Lemkos) from the south-eastern provinces of post-war Poland, to the Recovered Ter ...
in 1947. Large numbers of Ukrainians were forced to move from south-eastern Poland under a 1947 Polish government operation aimed at dispersing, and therefore assimilating, those Ukrainians who had not been expelled eastward already, throughout the newly acquired territories. Belarusians living around the area around Białystok were also pressured into relocating to the formerly German areas for the same reasons. This scattering of members of non-Polish ethnic groups throughout the country was an attempt by the Polish authorities to dissolve the unique ethnic identity of groups like the Ukrainians, Belarusians and Lemkos, and broke the proximity and communication necessary for strong communities to form.

Polish and Soviet newspapers and officials encouraged Poles to relocate to the west – "the land of opportunity".[ These new territories were described as a place where opulent villas abandoned by fleeing Germans waited for the brave; fully furnished houses and businesses were available for the taking. In fact, the areas were devastated by the war, the infrastructure largely destroyed, suffering high crime rates and looting by gangs. It took years for civil order to be established.
In 1970, the Polish population of the Northern and Western territories for the first time caught up to the pre-war population level (8,711,900 in 1970 vs 8,855,000 in 1939). In the same year, the population of the other Polish areas also reached its pre-war level (23,930,100 in 1970 vs 23,483,000 in 1939).]
While the estimates of how many Germans remained vary, a constant German exodus took place even after the expulsions. Between 1956 and 1985, 407,000 people from Silesia

Role of the Recovered Territories in the Communists' rise to power
The Communist government, not democratically legitimized, sought to legitimize itself through anti-German propaganda. The German "revanchism" was played up as a permanent German threat, with the Communists being the only guarantors and defenders of Poland's continued possession of the "Recovered Territories". Gomułka asserted that:
The western territories are one of the reasons the government has the support of the people. This neutralizes various elements and brings people together. Westward expansion and agricultural reform will bind the nation with the state. Any retreat would weaken our domestic position.
The redistribution of "ownerless property" among the people by the regime brought it broad-based popular sympathy.
After the Second World War, the Soviet Union annexed the Polish territory of the Kresy
Eastern Borderlands ( pl, Kresy Wschodnie) or simply Borderlands ( pl, Kresy, ) was a term coined for the eastern part of the Second Polish Republic during the History of Poland (1918–1939), interwar period (1918–1939). Largely agricultural ...

Legal status of the territories
During the Cold War the official position in the First World was that the concluding document of the Potsdam Conference was not an international treaty, but a mere memorandum. It regulated the issue of the German eastern border, which was to be the Oder-Neisse line, but the final article of the memorandum said that the final status of the German state and therefore its territories were subject to a separate peace treaty between Germany and the Allies of World War II. During the period from 1945 to 1990 two treaties between Poland and both East Germany, East and West Germany

signed the Treaty of Zgorzelec, recognizing the Oder-Neisse line, officially designated by the Communists as the "Border of Peace and Friendship". On 7 December 1970 the Treaty of Warsaw (1970), Treaty of Warsaw between the Federal Republic of Germany and Poland was signed concerning the Polish western border. Both sides committed themselves to nonviolence and accepted the existing ''de facto'' border—the Oder-Neisse line. However a final treaty was not signed until 1990 as the "Treaty on the Final Settlement With Respect to Germany".
Until the Treaty on the Final Settlement, the West German government regarded the status of the German territories east of the Oder-Neisse rivers as that of areas "temporarily under Polish or Soviet administration". To facilitate wide international acceptance of German reunification in 1990, the German political establishment recognized the "facts on the ground" and accepted the clauses in the Treaty on the Final Settlement whereby Germany renounced all claims to territory east of the Oder-Neisse line. This allowed the treaty to be negotiated quickly and for unification of democratic West Germany and socialist East Germany to go ahead quickly.
In accordance with a duty imposed on Germany by the Treaty on the Final Settlement, in the same year, 1990, Germany signed a separate treaty with Poland, the German-Polish Border Treaty, confirming the two countries' present borders.
The signature and ratification of the border treaty between Germany and Poland formalized in international law the recognition of the existing border and put an end to all qualified German claims.
