COVID Lockdowns Echoed Centuries-Old Pandemic Shifts in Migrant Language Use

When COVID-19 lockdowns confined families to their homes, they did more than disrupt work and schooling. According to a new study of Russian- and Polish-speaking migrant communities in Germany, the pandemic reorganized who spoke which language to whom—and it did so in ways that strikingly resemble patterns documented during epidemics stretching back to the Black Death. The research, published in Frontiers in Education by Vladislava Warditz of the University of Cologne, argues that COVID-19 was not a linguistic anomaly but the latest manifestation of a historically recurring pattern in which epidemics redistribute language practices across social domains.

The study builds a bridge between historical sociolinguistics and contemporary migration research. Drawing on documented cases from the Justinianic Plague of 541 to 750, the Black Death of 1347 to 1353, the nineteenth-century cholera pandemics of 1817 to 1923, and the 1918 influenza pandemic, the author identifies three recurring mechanisms through which epidemics reshape language use. First, outbreaks create new multilingual contact spaces, such as quarantine stations, hospitals, and border checkpoints, where translation and linguistic accommodation become essential. Second, medical and administrative communication temporarily incorporates diverse languages, including minoritized ones, expanding their public functions. Third, mobility restrictions shift communication toward the household, temporarily strengthening minoritized languages within domestic life. These mechanisms are presented as an analytical synthesis rather than deterministic laws, allowing for variation across periods and sociolinguistic settings.

The historical evidence for these mechanisms is concrete. During cholera waves in the 1830s to 1850s, quarantine stations along the Habsburg Military Frontier and Danube regions operated in German as an administrative language alongside Hungarian and South Slavic dialects, reflecting multi-ethnic governance. In the Russian Empire, cholera quarantines in the Volga region brought together Russian-, Tatar-, and German-speaking populations, requiring interpreters and multilingual sanitary regulations. Eighteenth- and nineteenth-century quarantine passports and health certificates were often issued in several languages to secure compliance across linguistic communities. In each case, effective communication took precedence over established language hierarchies, temporarily expanding the functional use of minoritized languages and dialects in administrative settings.

To test whether these mechanisms operate under contemporary conditions, the study examined two of Germany’s largest migrant-origin communities, both of which emerged primarily through mass, state-supported emigration from Poland and the former Soviet Union after 1989. The two languages differ in important sociolinguistic respects. Russian functions as a lingua franca across post-Soviet diasporic communities, including migrants from Kazakhstan, Ukraine, Belarus, and Tatarstan, giving it a broader communicative reach and a rich digital ecosystem. Polish is more closely tied to families of Polish origin and to national ethnic identity, and is often transmitted in colloquial, contact-influenced varieties with limited institutional support. In Germany, roughly 12 percent of the population reports speaking Russian at home and 7 percent Polish, according to survey data cited in the study.

The empirical core of the research is a qualitative interview corpus collected in Germany between March and June 2022, after the easing of major restrictions. Fifty-two parents aged 25 to 45 took part—36 Russian-speaking and 16 Polish-speaking—each recruited from an earlier four-country survey conducted between January and May 2022 as part of the German-Israeli project Multilingual Families’ Response to COVID-19. Interviews of roughly 7,500 words each were conducted in Russian or Polish, transcribed, and analyzed thematically, with participants’ reported language use coded into four categories: increased heritage-language use, increased German use, no noticeable change, and changed conditions without a clear shift.

The results revealed a marked asymmetry between the two communities. Among the Russian-speaking participants, fourteen of thirty-six reported increased use of Russian during the pandemic, five reported increased German, fourteen reported no change, and three gave no information. Respondents attributed the increase in Russian to two mechanisms: lockdowns created more time for parent-child communication, and families made intensive use of Russian-language digital resources such as films, cartoons, and educational materials. In monolingual households, prolonged kindergarten closures also reduced children’s exposure to German. By contrast, among the sixteen Polish-speaking participants, twelve reflected on lockdown effects, and eight of those twelve reported little or no change, crediting established family language routines. Where changes appeared, they reflected altered opportunities for contact—more time with relatives, or, for one respondent, less Polish because travel restrictions cut off visits to grandparents in Poland.

These qualitative patterns complement the earlier quantitative survey, which covered migrant families in Germany, Cyprus, Israel, and Sweden. That survey found overwhelmingly positive attitudes toward multilingualism among both communities in Germany and, paradoxically, a pandemic-era shift in reported practices toward the heritage languages, particularly in communication with mothers and grandparents, even though respondents valued the societal language German highly. For Russian, the findings aligned with the diaspora’s transnational character; for Polish, context mattered more, with a shift toward family use of Polish observed in Germany but not in the other three countries. The interview data thus support the study’s second hypothesis: despite sharing a migratory context, the two communities experienced the pandemic’s linguistic effects differently.

Situated within the historical framework, the findings map most directly onto the third mechanism—the reorganization of domestic language practices—with the first two mechanisms shaping communicative conditions only indirectly. Yet the study also documents a significant modification of the first mechanism. Whereas earlier epidemics generated new multilingual contact spaces in physically co-present settings such as hospitals, quarantine facilities, and border checkpoints, during COVID-19 these spaces migrated largely into digital environments, where multilingual mediation became central to access to institutions, education, and transnational communication. This digital relocation supports the study’s first hypothesis, that transnational digital communication constitutes a genuinely new feature of pandemic-era language change. The pandemic also produced a paradox: multilingualism, including heritage languages, gained institutional relevance as a pragmatic resource, even as lockdowns simultaneously increased heritage-language use in private domestic spheres. Both dynamics raised the prominence and visibility of these languages.

The study concludes that the pandemic changed the conditions of language transmission—less in-person contact, more online interaction—without changing families’ overall goal of multilingual transmission, with heritage languages functioning as practical resources in a migratory context. For both communities, lockdown primarily intensified or stabilized existing practices rather than transforming them. The author notes that the multilingual orientation observed in both samples, in which the symbolic and pragmatic values attached to Russian and Polish proved less decisive than the pragmatic value of multilingualism itself, contrasts with the strong monolingual orientation documented in earlier sociolinguistic research on migrant communities in the United States, and corresponds to a broader European policy orientation toward multilingualism articulated since the 2000s. Language maintenance was further supported by an established community infrastructure, including heritage-language instruction in schools and universities, afternoon schools, and cultural associations.

The study is not without limitations, which the author explicitly acknowledges. The historical comparison draws on documented cases of differing scope and detail, so the three mechanisms remain an analytical synthesis rather than a tested causal model. Language use was self-reported rather than independently observed, meaning the findings reflect participants’ retrospective accounts of their practices. The qualitative sample of fifty-two interviews is also relatively small, and the datasets are not publicly available due to privacy and ethical restrictions. Future research, the study suggests, should examine institutional communication and digital multilingual contact spaces directly, complement self-reported data with systematically recorded evidence, and extend the historical comparison to further epidemic contexts and migrant communities. Even with these caveats, the work offers a historically informed account of how global crises can quietly reshape the languages spoken at kitchen tables—rearrangements that, the evidence indicates, have been recurring for well over a millennium.
