Sovereignty, Nationalism and the Quest for Homogeneity in Interwar Europe is Out

The volume is available in hardback and in open access online

Were European empires ‘prisons of nations’? Did minority questions exist exclusively in eastern Europe during the interwar years? How did ordinary people in minority regions navigate conflicting forms of national identification? How did minority representatives mobilise support for minority rights transnationally? In fourteen chapters, Sovereignty, Nationalism and the Quest for Homogeneity in Interwar Europe answers these and other questions.

Proposing an unusual juxtaposition, the first part of the volume examines three empires (Austria-Hungary, the United Kingdom, and the Ottoman Empire) that, although on different scales, experienced crisis and partition at the end of the Great War. Pieter Judson shows how imperial forms of governance in the Austrian part of the Habsburg Empire gave more space to people to speak their preferred language and to embrace a wider array of self-understandings than the nation-states that followed. The United Kingdom is often examined as a nation-state rather than a union state. By contrast, Alvin Jackson considers it as a composite monarchy and dissects the centrifugal and centripetal forces that led to Britain’s partial break-up, but also to its survival after the First World War. Erol Ülker closes this first part of the volume by examining majority-minority relations in the Ottoman Empire from 1908 to 1923. He concludes that Turkish policies toward non-Turkish minorities were more complex and varied than recognised by traditional accounts.

The second part of the book studies comparatively minority policies in interwar Europe. It demonstrates that minority questions were debated throughout the continent and that the allegedly ‘civilised’ West did not treat minorities more liberally than the supposedly ‘backward’ East. Volker Prott compares violence in Alsace-Lorraine and Asia Minor. He highlights how a temptation to coercively homogenise populations was inherent in the post-war international order, but also identifies factors that restrained large-scale violence. Then, Mona and Emmanuel consider Belgium, Italy, and Spain as nationalising states. They show how these countries adopted homogenising policies with varying degrees of coercion and thus debunk some lingering myths of populations’ homogeneity in interwar western Europe. Marina Germane examines minority policies and mobilisation in Latvia, Poland, and Romania. Following German and Jewish representatives, she investigates the limits of domestic mobilisation and how disillusion pushed activists to move their activities from domestic arenas to the transnational sphere. In the last chapter of this part of the book, Sabine Dullin dissects the USSR’s double-edged nationality policy. She argues that the Soviets promoted national cultures throughout the Union, but also saw minorities as dangerous fifth columns and targets of collective punishment and forced displacement.

Part three of the book examines from the bottom-up processes of identification in different European contexts. It builds upon, but also challenges the national indifference framework. The chapter in this part emphasise how the space for indifference shrank in an increasingly nationalising interwar Europe. Olga Linkiewicz zooms in on rural conflicts in eastern Poland during the 1924 language plebiscite. She shows how peasants behaved in accordance with the principles of a vernacular cosmology that defies easy categorisation as either national indifference or full Polish nationalisation. Brian Hughes explores strategies of everyday resistance among loyalists during and after the Irish Revolution. He dissects the meaning of loyalism, as well as dynamics of integration and assimilation within an increasingly Catholic and Gaelic Irish Republic. Alison Carrol closes this part of the book revisiting Alsace’s return to France. She explores how different groups within Alsatian society pushed the state to adopt flexible policies of integration that created unexpected spaces for alternative understandings of identity.

Part four of the volume follows minority representatives across borders and gauges their efforts to lobby foreign governments, international organisations and the broader international community in favour of the defence of minority rights. Xosé Manoel Nuñez Seixas and David Smith map transnational networks of minority rights advocacy across Europe. They identify the emergence of a transnational nationality theory that, despite its failure, constituted an alternative to the model of the homogenous nation-state in interwar Europe. Jane Cowan explores the triangular, asymmetric and non-reciprocal relation between the Women’s International League for Peace and Freedom (WILPF), Bulgarian and Macedonian female activists and the male-dominated League of Nations. She shows how, in their interactions, these actors navigated hierarchies of gender, class, race, and civilisation.

Omer Bartov closes the book with a broad-ranging coda on the ‘conundrum of national indifference’. National indifference, he argues, rightly reminds us to be sceptical of the arguments of nationalist zealots. The history of the 20th century, as well as the recent Russian aggression of Ukraine, equally reminds us that we downplay the power of nationalism at our own peril. As Bartov and many other contributors suggest, although nationhood was not the only form of identification in interwar Europe, or the most important, the space for indifference shrank considerably between the two World Wars, in Poland and Romania, but also in Italy, France and Ireland.

The Pursuit of Polish Homogeneity following World War II

We are proud to publish here the fourth post of our “Minorities in Contemporary and Historical Perspectives” series, which looks at majority-minority relations in a multi-disciplinary and diachronic perspective. Today’s contribution, by John Kulczycki (University of Illinois at Chicago), looks at the efforts of post-WW II Poland to homogenize the population of the so-called Recovered Lands in the west of the country. The series is a collaboration with H-Nationalism.

At the Potsdam Conference in 1945, the three Great Powers had the task of demarking Poland’s western border. During the plenary session on 21 July, President Harry Truman decried that the Soviets had already handed over eastern Germany to the Poles.[1] On his insistence, the conference communiqué stated that “the final delimitation of the western frontier of Poland should await the peace settlement.” Yet, a provision approving “the transfer to Germany of German populations” undermined this caveat.[2]

Polish nationalists claimed eastern Germany on historical grounds as part of the Polish kingdom during the tenth to fourteenth centuries.[3] Government officials referred to the territories collectively as the Recovered Lands (Ziemie Odzyskane), an unconscious part of ordinary speech even after the fall of communism.[4] Polish nationalists also claimed the area on ethnic grounds. As the Polish ambassador in Moscow informed his British and American colleagues on 10 July 1945, “Fairly large territories with a preponderating Polish element were not included within the boundaries of Poland in the years 1918-1939.” “[S]he has to return to her primordial lands, and to continue the old political tradition . . . as a national state.”[5] Integration of the Recovered Lands required the “transfer” of Germans, but the retention of “autochthons,” i.e., indigenous German citizens of Polish origin.

Identifying Autochthons

 How to recognize Polish elements who lived under German rule and cultural influence for centuries? Many residents of the Recovered Lands identified primarily with their religion and region and were nationally indifferent or without an irrevocable attachment to a nationality despite the nationalizing efforts of the Nazi regime during the war, when national or ethnic identity could mean the difference between life and death.[6]

 On 19 February 1945 an organization of enthusiasts of westward expansion, the Polish Western Union (Polski Związek Zachodni), advocated “nationality verification” based on a variety of criteria: active participation in the struggle for Polishness and membership in a Polish organization, knowledge of the Polish language and its usage in daily life, and evidence of Polish origin, such as a Polish-sounding surname and Polish family ties and traditions.[7]         

Lacking guidelines from the central government, regional authorities pursued their own approaches.[8] On 22 March 1945 Silesian Governor Aleksander Zawadzki directed officials to protect “Polish souls” by issuing provisional affidavits of Polishness to applicants who “unquestionably belong to the Polish nationality.”[9] These “Polish souls” had to present a document certifying membership in a Polish organization or the testimony of three individuals of unquestioned Polish nationality. A further directive on 7 April 1945 added the use of Polish in the home and in prayer as well as the ability to read and write in Polish and ordered the formation of special commissions of local individuals “of undoubtedly Polish nationality” to decide who should receive Polish citizenship.[10]

In Mazuria, however, Plenipotentiary Jakub Prawin on 24 April 1945 called on Poles of local origin to register for provisional affidavits of membership in the Polish nation.[11] On 26 May 1945 his deputy instructed officials that a lack of documentation of Polish origin, such as a Polish-sounding surname, or an absence of Polish national consciousness, as when applicants declared themselves to be Mazurs, should not prevent certification as members of the Polish nation. Officials could also waive the requirement of a minimal knowledge of Polish in exceptional cases for individuals connected to the Polish nation. Nevertheless, officials were to examine an applicant’s past so as not to protect “foreign elements, enemies of the Polish Nation, or those encumbered with anti-Polish activity.”[12] If approved by a local Polish Nationality Committee, the applicant received a permanent affidavit of Polishness.

Whereas elsewhere the initial directives meant that whoever is not Polish is German, in Mazuria the authorities recognized as Polish all who were not German, requiring little more than a declaration of loyalty. This took into account the region’s unusual character. Mazurs spoke an archaic form of Polish, but unlike most Poles, they were overwhelmingly Protestant. The Nazis classified them as “racial Germans” without a process of individual verification. Indeed, Mazuria was a hotbed of Nazi support. Therefore, Polish activists in Mazuria favored a preemptive collective recognition of Mazurs as Polish citizens instead of individual verification, excluding solely those individuals unquestionably German.[13]

Because of a rigid definition of Polishness as well as the perception of Mazurs as Germans, officials balked at carrying out the directives. On 7 June 1945 Prawin threatened officials with sanctions, admonishing them:

Let the Polish citizen remember that the Kashub, Pomeranian, Warmiak, Mazur—we all, despite these or other religious, political, or social beliefs, are children of one blood of fraternal clans and Polish tribes, and this without regard to whether our closer or more distant compatriots are today conscious of their Polish origin or not. . . . I categorically direct you to register as Poles . . . all individuals identifying themselves as Kashubs, Pomeranians, Warmiaks, Mazurs without demanding of them additional declarations in this regard and to recognize those so registered as Polish citizens.

Revocation of citizenship could only occur after its bestowal: if “it is proven in an administrative and legal way that someone himself consciously of his own criminal instinct acted against Poles and Poland, then of course the Polish citizenship granted him will be withdrawn.”[14]­­­­­­­­­­­­­­­­­­­­

On 20 June 1945 the Minister of Public Administration, who had jurisdiction over the Recovered Lands, addressed the issue of nationality verification, authorizing governors and plenipotentiaries to issue provisional three-month affidavits of citizenship pending verification to those who inhabited the territory before the war and “belong to the Polish nationality” following a declaration of loyalty. But he did not define the criteria for membership in the Polish nation, except for specifically excluding former members of the Nazi party and “fascist-Nazi criminals.” On 23 June 1945 the director of the Legal Department of the provisional parliament, argued that the criteria should be left to administrative and public security organs, which had the necessary information to separate Poles from Germans, and any regulation should await the peace treaty between Germany and the Allied powers.[15]

Obstacles to Differentiating Germans from Poles

Initially, Governor Zawadzki advocated recognizing only those who “unquestionably belong to the Polish nationality.” By October 1945 he admitted, “No paragraphs and no directives clearly reveal who should be regarded as a Pole and who as a German—in such cases the Polish conscience must decide.”[16] But the officials responsible for verification came mostly from prewar Poland and had no knowledge of conditions under German rule. Furthermore, their competence and integrity frequently declined the lower one went down the administrative hierarchy. Many simply regarded the autochthons as Germans and often targeted for expulsion those with homes and farms that officials could confiscate for themselves or others from prewar Poland. As a result, the mass expulsion from the Recovered Lands that reached its apogee in 1946 included many who qualified for Polish citizenship.

A report on 2 June 1947 of the Department of Inspection of the Ministry of Recovered Lands went to the heart of the matter: “The greatest difficulty in asserting whether a given individual is of Polish origin or not is the lack, or even the impossibility of creating an objective criterion that would differentiate a German from an autochthon.” Furthermore, the decisions concerning verification varied widely. “For some the fact of having a Polish name is enough, and for the authorities to acknowledge the Polishness of others, knowledge of the Polish language and, say, one witness confirming the applicant’s Polish origins is not enough.” “Especially dangerous is the fact that at times individuals already verified are suddenly deprived of their certification of Polish nationality because of a denunciation that the autochthon speaks German at home or has postal contact with Germany and therefore is a German, not a Pole.” Many autochthons “prefer to leave as Germans bearing their Polishness in secret rather than as spurned to whom the right to Polishness was denied and to whom is pinned the mark of treason in the eyes of their fellow Germans.” In addition, “unregulated matters of property” prevent an autochthon deprived of his property from applying for verification: “in practice the greatest number of denunciations is inspired or directed by the current Polish occupants, who in case the autochthon is verified would have to return this property.”[17]

The End of Mass Expulsion

In July 1947 the British refused to accept the last 50,000 Germans that the Poles wanted to expel to the British zone of occupied Germany. In October 1947 the Soviets announced that mass resettlement to their zone would end in November 1947.[18] The imminent halt to mass expulsion focused attention on autochthons who refused to apply for nationality verification. 

In 1947 Silesia, with the largest concentration of autochthons, saw the most vigorous campaign of “re-Polonization,” based on the assumption that autochthons were essentially Polish. Yet, troubling signs of German influence and incomplete re-Polonization persisted. The Ministry of Public Affairs blamed primarily German machinations and falsifications during verification.[19] In the last months of 1947 nationality commissions reversed 1,062 decisions affecting individuals verified as Polish, and 14,650 cases were pending. Contrary to the law, the commissions revoked citizenship without the approval of local officials. The governor, however, saw the expulsion of Germans as more important.[20]

With the end of mass expulsion, the authorities faced the problem of thousands of autochthons not yet verified as Polish. In Olsztyn province, formerly Mazuria, Governor Mieczysław Moczar resorted to repressive measures in the so-called “Great Verification.” On 8 January 1949, he declared, “We desire with all our strength not to lose a single Pole, but we must be very severe in relation to those who are espousing pro-Nazi propaganda,” a reference to those defending Mazurs or resisting verification.[21] The administration mobilized local cadre together with the militia and security forces to target over 20,000 autochthons with various forms of pressure, including physical force.[22] Indeed, on 30 March 1949 the International Committee of the Red Cross informed the Ministry of Public Administration of an increasing number of complaints, mainly from Mazuria, of German citizens forced to request Polish citizenship.[23]

Superficially, Moczar made progress. A report on 1 April 1949 claimed that nearly 19,000 natives were verified in the previous three months.[24] But the use of force and repression strengthened the aversion of Mazurs to Polish officialdom and their existing situation, and they generally continued to identify as Germans.[25]

The Epilogue

Too late for most Mazurs, declarations of regional and national identities became officially possible when the 2011 census allowed inhabitants to indicate one or two national-ethnic identities. No Mazurs identified themselves as such, but 44.4 percent of those who declared a Silesian identity gave it as their sole identity as did 30.4 percent of Germans. Superficially, the postwar nationality policies succeeded: 94.8 percent of Poland’s population declared Polish as its sole identity.[26] This success came in part through the more or less forced departure and alienation of many who could have been loyal citizens contributing to Poland’s reconstruction after the war had these policies and their implementation been different.
