Introduction
Migration, once primarily viewed through economic and humanitarian lenses, has increasingly become a matter of national security in recent decades. This shift, often termed ‘securitisation,’ refers to the process by which migration is framed as a threat to societal stability, border integrity, and national identity, thereby justifying exceptional measures to control it. Within the field of International Relations, the securitisation of migration is a critical topic that reflects broader geopolitical tensions, state sovereignty concerns, and the interplay of global and local dynamics. This essay aims to explore how migration has been securitised since the late 20th century, focusing on key drivers such as post-Cold War geopolitical changes, the impact of terrorism after 9/11, and the role of populist rhetoric in shaping policy and public perceptions. By examining relevant theoretical frameworks and case studies, particularly in the European and North American contexts, the essay will highlight the mechanisms through which migration has been transformed into a security issue, as well as the implications of this trend.
Theoretical Framework of Securitisation
The concept of securitisation, developed by the Copenhagen School of Security Studies, provides a useful lens to understand the transformation of migration into a security concern. According to Buzan et al. (1998), securitisation occurs when an issue is presented as an existential threat to a referent object (e.g., the state or society), prompting extraordinary measures beyond normal political processes. In the context of migration, states and political actors often frame incoming populations as potential risks to economic stability, cultural identity, or public safety, thereby legitimising stringent border controls and surveillance mechanisms. While this framework is insightful, it is not without critique; some scholars argue it oversimplifies the complex motivations behind policy decisions, which may also stem from bureaucratic or economic interests rather than purely security concerns (Balzacq, 2011). Nevertheless, the securitisation paradigm remains a valuable starting point for analysing how migration has been positioned as a threat over recent decades.
Post-Cold War Geopolitical Shifts
The end of the Cold War in the early 1990s marked a significant turning point in the securitisation of migration. During this period, the dissolution of bipolar power structures led to increased regional conflicts and economic disparities, particularly in Eastern Europe, Africa, and the Middle East, driving waves of asylum seekers and economic migrants towards Western states. Western governments, grappling with the uncertainty of a new world order, began to view unregulated migration as a potential source of instability. For instance, the 1990s saw the European Union (EU) tightening its external borders through agreements like the Schengen Accord, which, while promoting internal mobility, also reinforced a ‘fortress Europe’ mentality (Huysmans, 2000). This era also witnessed the linking of migration with transnational crime, such as human trafficking and smuggling, further embedding the issue within security discourses. Although the immediate post-Cold War period did not uniformly securitise migration across all states, it arguably laid the groundwork for later, more intensified responses by framing migration as a challenge to state sovereignty.
The Impact of 9/11 and the War on Terror
The terrorist attacks of September 11, 2001, represented a watershed moment in the securitisation of migration, particularly in the United States and its allies. The subsequent ‘War on Terror’ fostered a direct association between migration and terrorism, with policymakers and media outlets often portraying migrants—especially those from Muslim-majority countries—as potential security risks. In the US, the creation of the Department of Homeland Security and the implementation of the USA PATRIOT Act in 2001 significantly expanded surveillance and detention mechanisms targeting immigrants (Lazaridis and Wadia, 2015). Similarly, in Europe, the 2005 London bombings further intensified calls for stricter immigration controls, despite limited evidence linking these events directly to migration flows. Critics argue that such policies disproportionately target specific ethnic and religious groups, reinforcing stereotypes and social exclusion (Huysmans, 2006). This period illustrates how securitisation can be driven by specific, high-profile events, even when the broader empirical evidence of migration as a threat remains tenuous.
Populism and the Framing of Migration as a Cultural Threat
In more recent years, the rise of populist movements in Europe and North America has further entrenched the securitisation of migration, often by framing it as a cultural rather than purely physical threat. Leaders and political parties, such as the UK Independence Party (UKIP) during the Brexit campaign or Donald Trump in the US, have capitalised on public anxieties about globalisation and demographic change, depicting migrants as challenges to national identity and social cohesion. The 2015 European migrant crisis, during which over a million refugees arrived fleeing conflict in Syria and elsewhere, became a focal point for such rhetoric. Governments responded with emergency measures, including border closures in Hungary and increased naval patrols in the Mediterranean, justified on the grounds of protecting national interests (Greenhill, 2016). While these responses addressed real logistical challenges, they often overstated the threat posed by migrants, sidelining humanitarian considerations. This trend highlights how securitisation is not solely a state-driven process but can also be amplified by societal and political dynamics.
Consequences and Implications
The securitisation of migration has profound implications for both policy and society. On one hand, it has led to the normalisation of exceptional measures, such as mass detentions and militarised borders, which can undermine human rights and international obligations like the 1951 Refugee Convention. On the other hand, it risks deepening social divisions by fostering mistrust towards migrant communities, as seen in the rise of hate crimes in several Western countries following anti-immigrant rhetoric (Lazaridis and Wadia, 2015). Furthermore, by prioritising security over economic or humanitarian perspectives, states may overlook the potential benefits of migration, such as labour market contributions and cultural enrichment. Critically, the securitisation process tends to be self-perpetuating; once framed as a threat, migration becomes increasingly difficult to discuss outside a security lens, limiting policy innovation. Addressing these challenges requires a more balanced discourse, though achieving this in the current political climate remains a complex task.
Conclusion
In conclusion, the securitisation of migration in recent decades reflects a multifaceted process driven by geopolitical shifts, high-profile security events like 9/11, and the rise of populist narratives. Through the lens of the Copenhagen School’s securitisation theory, it is evident that states and political actors have framed migration as an existential threat to justify extraordinary measures, often at the expense of humanitarian considerations. From the post-Cold War era’s border tightening to the post-9/11 emphasis on terrorism and the cultural anxieties stoked by populism, migration has been consistently positioned within security discourses, with significant social and policy consequences. Moving forward, there is a pressing need to critically evaluate these trends, balancing legitimate security concerns with the rights and contributions of migrants. Only through such reflection can the international community hope to address the complexities of migration in a globalised world.
