 the term "Corridor" was first used by Polish politicians, while Polish historian Grzegorz Lukomski writes that the word was coined by German nationalist propaganda of the 1920s. Internationally the term was used in the English language already as early as March 1919 and whatever its origins, it became a widespread term in English language usage.

The equivalent German term is Polnischer Korridor. Polish names include korytarz polski ("Polish corridor") and korytarz gdański ("Gdańsk corridor"); however, reference to the region as a corridor came to be regarded as offensive by interwar Polish diplomacy. Among harshest criticizers of the term corridor was Polish Foreign Minister Józef Beck

"An independent Polish state should be erected which should include the territories inhabited by indisputably Polish populations, which should be assured a free and secure access to the sea, and whose political and economic independence and territorial integrity should be guaranteed by international covenant."


The following arguments were behind the creation of the corridor:

Ethnographic reasons

Ethnic situation was one of the reasons for returning the area to the restored Poland. The majority of the population in the area was Polish. As the Polish commission report to the Allied Supreme Council noted on 12 March 1919: "Finally the fact must be recognised that 600,000 Poles in West Prussia would under any alternative plan remain under German rule". The Prussian census of 1910 showed that there were 528,000 Poles (including West Slavic Kashubians

, who had supported the Polish national lists in German elections) in the region compared with 385,000 Germans (including troops stationed in the area). The Poles did not want the Polish population to remain under the control of the German state, which had in the past treated the Polish population and other minorities as second-class citizens and pursued Germanization.

It is only fair that the claim of the river-basin should prevail against that of the seaboard.".

Economic reasons

, Poland's economic independence would be illusory. Around 60.5% of Polish import trade and 55.1% of exports went through the area. The report of the Polish Commission presented to the Allied Supreme Council said:
"1,600,000 Germans in East Prussia can be adequately protected by securing for them freedom of trade across the corridor, whereas it would be impossible to give an adequate outlet to the inhabitants of the new Polish state (numbering 25,000,000) if this outlet had to be guaranteed across the territory of an alien and probably hostile Power."

Military personnel was included in the population census. A number of German civil servants and merchants were introduced to the area, which influenced the population status.

According to Richard Blanke, an American historian of German descent, 421,029 Germans were living in the area in 1910, making up 42.5% of the population. Blanke has been criticised by Christian Raitz von Frentz, his book classified by him as part of a series on the subject that have an anti-Polish bias, additionally Blanke's views have been described by Polish professor A. Cienciala as sympathetic to Germany. In addition to the military personnel included in the population census, a number of German civil servants and merchants were introduced to the area, which influenced the population mix, according to Andrzej Chwalba. By 1921 the proportion of Germans had dropped to 18.8% (175,771). Over the next decade, the German population decreased by another 70,000 to a share of 9.6%.

As a result, a large number of Germans left Poland after the war: According to Wolff, 800,000 Germans had left Poland by 1923, according to Gotthold Rhode, 575,000 left the former province of Posen and the corridor after the war, according to Herrmann Rauschning, 800,000 Germans had left between 1918 and 1926, contemporary author Alfons Krysinski estimated 800,000 plus 100,000 from East Upper Silesia, the contemporary German statistics say 592,000 Germans had left by 1921, other Polish scholars say that up to a million Germans left. Polish author Władysław Kulski says that a number of them were civil servants with no roots in the province and around 378,000, and this is to a lesser degree is confirmed by some German sources such as Hermann Rauschning.
The question whether many of the Germans who left were actually settlers without roots in the area, has been raised by Lewis Bernstein Namier who remarked in 1933 "a question must be raised how many of those Germans had originally been planted artificially in that country by the Prussian Government."

According to the above mentioned Richard Blanke, in his book Orphans of Versailles, several reasons for the exodus of the German population are given.
  • A number of former settlers from the Prussian Settlement Commission who settled in the area after 1886 in order to Germanise it were in some cases given a month to leave, in other cases they were told to leave at once.
  • Poland found itself under threat during the Polish-Bolshevik war, and the German population feared that Bolshevik forces would control Poland. Migration to Germany was a way to avoid conscription and participation in the war.
  • State-employed Germans such as judges, prosecutors, teachers and officials left as Poland did not renew their employment contracts. German industrial workers also left due to fear of lower-wage competition
    Competition

It arises whenever two and only two strive for a goal which cannot be shared. Competition occurs naturally between living organisms which co-exist in the same environment. For...

  • Germans refused to accept living in a Polish state. As Lewis Bernstein Namier

     said: "Some Germans undoubtedly left because they would not live under the dominion of a race which they had previously oppressed and despised."
  • Germans feared that the Poles would seek reprisals after over a century of harassment and discrimination

     by the Prussian and German state against the Polish population.
  • Social and linguistic isolation: While the population was mixed, only Poles were required to be bilingual. The Germans usually did not learn Polish. When Polish became the only official language in Polish-majority provinces, their situation became difficult. The Poles shunned Germans, which contributed to their isolation.
  • Lower standards of living. Poland was a much poorer country than Germany.
  • Former Nazi politician and later opponent Hermann Rauschning
    Hermann Rauschning

     wrote that 10% of Germans were unwilling to remain in Poland regardless of their treatment, and another 10% were workers from other parts of the German Empire with no roots in the region.


Blanke says that official encouragement by the Polish state played a secondary role in the exodus. Christian Raitz von Frentz notes "that many of the repressive measures were taken by local and regional Polish authorities in defiance of Acts of Parliament and government decrees, which more often than not conformed with the minorities treaty, the Geneva Convention and their interpretation by the League council - though it is also true that some of the central authorities tacitly tolerated local initiatives against the German population." While there were demonstrations and protests and occasional violence against Germans, they were at a local level, and officials were quick to point out that they were a backlash against former discrimination against Poles. There were other demonstrations when Germans showed disloyalty during the Polish-Bolshevik war as the Red Army announced the return to the prewar borders of 1914. Despite popular pressure and occasional local actions, perhaps as many as 80% of Germans emigrated more or less voluntarily.

Helmutt Lippelt writes that Germany used the existence of German minority in Poland for political means and as part of its revisionist demands, which resulted in Polish countermeasures.As partial reaction to German revisionist claims the Polish Prime-Minister Władysław Sikorski stated in 1923, that the de-Germanization of these territories by liquidation of German properties and eviction of German "optaten" has to be ended quickly so that German nationalists will be educated that their view of temporary state of Polish western border is wrong.}

 in July 1920, the Polish authorities tried to prevent traffic through the Corridor, interrupting postal, telegraphic and telephone communication. On March 10, 1920, the British representative on the Marienwerder Plebiscite Commission, H.D. Beaumont, wrote of numerous continuing difficulties being made by Polish officials and added "as a result, the ill-will between Polish and German nationalities and the irritation due to Polish intolerance towards the German inhabitants in the Corridor (now under their rule), far worse than any former German intolerance of the Poles, are growing to such an extent that it is impossible to believe the present settlement (borders) can have any chance of being permanent.... It can confidently be asserted that not even the most attractive economic advantages would induce any German to vote Polish. If the frontier is unsatisfactory now, it will be far more so when it has to be drawn on this side (of the river) with no natural line to follow, cutting off Germany from the river bank and within a mile or so of Marienwerder, which is certain to vote German. I know of no similar frontier created by any treaty."

 various means were used to increase the amount of land owned by Germans at the expense of the Polish population. In Prussia, the Polish nobility had its estates confiscated after the Partitions, and handed over to German nobility. The same applied to Catholic monasteries. Later, the German Empire bought up land in an attempt to prevent the restoration of a Polish majority in Polish inhabited areas in its eastern provinces.
Christian Raitz von Frentz notes that measures aimed at reversing past Germanization included the liquidation of farms settled by the German government during the war under the 1908 law.

In 1925 the Polish government enacted a land reform program with the aim of expropriating landowners. While only 39% of the agricultural land in the Corridor was owned by Germans, the first annual list of properties to be reformed included 10,800 hectares from 32 German landowners and 950 hectares from seven Poles. The voivode of Pomorze, Wiktor Lamot, stressed that "the part of Pomorze through which the so-called corridor runs must be cleansed of larger German holdings". The coastal region "must be settled with a nationally conscious Polish population.... Estates belonging to Germans must be taxed more heavily to encourage them voluntarily to turn over land for settlement. Border counties... particularly a strip of land ten kilometers wide, must be settled with Poles. German estates that lie here must be reduced without concern for their economic value or the views of their owners'.

Prominent politicians and members of the German minority were the first to be included on the land reform list and to have their property expropriated.

The situation regarding the Free City and the Polish Corridor created a number of headaches for German and Polish Customs. The Germans requested the construction of an extra-territorial highway (to complete the Reichsautobahn Berlin-Königsberg) and railway through the Polish Corridor, connecting East Prussia to Danzig and Germany proper. If Poland agreed, in return they would extend the non-aggression pact for 25 years.

Some felt that the Danzig question was inextricably tied to the problems in the Polish Corridor and any settlement regarding Danzig would be one step towards the eventual loss of Poland's access to the sea. Hitler's credibility outside Germany was very low after the occupation of Czechoslovakia, though some British and French politicians approved of a peaceful revision of the corridor's borders.

In 1939, Nazi Germany made another attempt to renegotiate the status of Danzig; Poland was to retain a permanent right to use the seaport if the route through the Polish Corridor was to be constructed. However, the Polish administration distrusted Hitler and saw the plan as a threat to Polish sovereignty, practically subordinating Poland to the Axis and the Anti-Comintern Bloc while reducing the country to a state of near-servitude.
