Spain's Sahrawi citizenship law tests delicate ties with Morocco

Spain's Congress voted to approve a citizenship bill in September 2026 that would allow Sahrawis born in Western Sahara during the Spanish colonial period to acquire Spanish nationality through an expedited process. The measure passed 168 to 31, with 145 lawmakers abstaining, though it still requires Senate approval before becoming law. The vote opened a diplomatic wound that Madrid had been carefully tending, and in Rabat, officials watched with visible concern.

The bill creates a special pathway for people born in Western Sahara before September 29, 1977—when Spain ended its administration of the territory—to apply for Spanish citizenship without meeting the standard ten-year residency requirement. First-generation descendants of those born during Spanish rule would also qualify. For eligible Sahrawis already living in Spain, the residency clock would reset to just two years instead of a decade. Estimates suggest between 70,000 and 110,000 people could eventually qualify, though the range reflects genuine uncertainty about who falls within the law's scope. Once granted Spanish nationality, these individuals would automatically become European Union citizens, acquiring all the rights and protections that status confers.

Spain's supporters of the measure framed it as a reckoning with colonial history—an acknowledgment that people born under Spanish rule were left in legal limbo when Madrid withdrew in 1976. The country had used similar reasoning before. In 2015, Spain created a special citizenship pathway for Sephardic Jews who could demonstrate their heritage and connection to Spain, linking the measure to the expulsion of Jews beginning in 1492. The Sahrawi bill followed that precedent, treating nationality as a tool for addressing historical injustice rather than merely a technical administrative matter.

But Morocco saw the law differently. While the bill does not formally change Spain's official position—Madrid still supports Morocco's autonomy proposal for Western Sahara as the basis for resolving the dispute—the measure complicates that stance in ways both countries understood. The concern in Rabat was not primarily about territory. The law would not alter who controls Western Sahara, would not recognize an independent Sahrawi state, and would not grant Spanish citizenship holders any sovereignty over the land. Instead, Morocco worried about the relationship the law would forge between Spain and a potentially large community of Spanish and EU citizens with direct personal or family ties to Western Sahara. Many of those eligible Sahrawis live in refugee camps around Tindouf in Algeria, where the Polisario Front—the separatist movement seeking independence—maintains its headquarters and administers the camps. Others live within Western Sahara itself. Either way, the law would create a new constituency of European citizens with stakes in an issue central to Morocco's national interests.

The timing amplified the tension. In 2022, Prime Minister Pedro Sánchez's government had shifted course dramatically, backing Morocco's autonomy proposal after years of ambiguity. That decision had repaired a fractured relationship and opened the door to expanded cooperation on migration, security, and trade. The citizenship bill, arriving four years later, suggested that Spain's commitment to that partnership had limits—that Madrid could support Morocco's political solution while simultaneously legislating consequences of its own colonial past. From Morocco's perspective, the two issues could not be cleanly separated. Both concerned Western Sahara. Both involved how Spain understood its historical role in the territory.

The debate inside Spain revealed deeper fault lines. The governing Socialist Party and its coalition partner Sumar supported the bill. The conservative People's Party abstained. Vox opposed it. The disagreement centered on how Spain should reckon with its colonial legacy and which legal mechanisms were appropriate for doing so. That internal division mattered to Morocco because it showed the measure was not a technical adjustment to nationality law but rather part of a broader Spanish conversation about its past and its relationship with Western Sahara. Moroccan media and international outlets reported the potential for the law to strain Madrid-Rabat relations further.

Morocco's deeper concern involved Ceuta and Melilla, two Spanish cities on Morocco's northern coast that Rabat considers integral to its territory. Spain rejects that claim and treats the cities as non-negotiable Spanish sovereign territory. If Spain could invoke historical and colonial ties to create special citizenship pathways for Sahrawis, and had already done so for Sephardic Jews whose connection to Spain stretched back more than five centuries, Morocco could pose an uncomfortable question: why should its own historical and geographical relationship with Ceuta and Melilla be treated as irrelevant? For eight centuries, Muslim dynasties including the Almoravids and Almohads had ruled parts of the Iberian Peninsula. If history and geography could establish present-day legal rights in one direction, Morocco's argument went, they could do so in another.

The law would not change territorial control of Western Sahara or alter the UN-led political process meant to resolve the dispute. It would not formally revise Spain's support for Morocco's autonomy proposal. But it signaled something subtler and more consequential: that Spain's colonial history in Western Sahara was becoming a live political issue in Madrid, one that could reshape how the two countries understood their relationship and their obligations to each other. The Senate vote would come next, and with it, a test of whether Spain could maintain its diplomatic balance or whether the weight of historical reckoning would tip the scales.
