On July 30, 2026, enormous crowds crossed from Morocco into Spain’s North African enclave of Ceuta. Within hours, Spanish authorities estimated that roughly 72,000 had entered Ceuta, overwhelming a city of just 83,000 residents. Spain’s other North African enclave, Melilla, also experienced attempted crossings, albeit on a much smaller scale, and closed down its border crossing with Morocco later that day.

Madrid’s response involved roping in the police, military, and migrant services. Many who entered had little intention of remaining, with roughly 70,000 returning to Morocco over the next few days, leaving Spanish authorities to deal with hundreds of unaccompanied minors who stayed.

The “mass crossing” was preceded by several developments. Spain began the process of regularizing 500,000 undocumented migrants in April. And, in July, the country’s Supreme Court ruled that “migrants arriving by sea would not face immediate removal,” according to Euronews, which increased the country’s appeal as a destination for those looking to immigrate. “We discussed this ruling and its impact. We explained that this ruling was going to create a problem. And it did create a problem,” said a Moroccan senior official.

The incident, however, could not have occurred without at least the tolerance of Morocco’s government. Rabat denied involvement, while Spain’s interior minister, Fernando Grande-Marlaska Gómez, blamed “criminal mafias” for the crossings. Ceuta’s regional president, Juan Jesús Visas, however, claimed that the crossings were “if not orchestrated, at least encouraged or permitted by Morocco,” stated The Guardian.

Spain’s pledge on July 20 to rebuild ties and deepen cooperation with Algeria, Morocco’s regional rival, provided some incentive to fuel the crisis. On July 23, Spain also advanced a proposed legislation granting an expedited path to citizenship for Sahrawis born in Western Sahara when it was still a Spanish colony, before August 1977. The proposal would also extend to their descendants, further aggravating tensions between Madrid and Rabat.

Spain’s criticisms of Israeli and US military operations in the Middle East also strained relations with Washington, at a time when Morocco is assuming an important role in US regional diplomacy. Since joining the Abraham Accords in 2020, Morocco has developed close military, intelligence, and economic ties with Israel, while receiving US backing for its position on the Western Sahara. Spain has meanwhile emerged as one of Europe’s most vocal critics of Israeli policy in Gaza and has denounced the US and Israel’s war on Iran.

Meanwhile, the 2027 House Appropriations Committee report, accompanying a bill passed on July 15, gave credence to Morocco’s claims over Ceuta and Melilla, reinforcing Rabat’s confidence. Against this backdrop, the situation in Ceuta unfolded as tensions between Spain and an increasingly aligned Morocco, Israel, and the US were already mounting. Jerusalem and Washington had little incentive to defend Madrid as Rabat has become an increasingly important partner to both. Israeli and American figures subsequently seized on the Ceuta crisis to criticize Madrid’s “liberal migration policy” and the Sanchez government.

The episode, while another demonstration of how governments can employ migration as an instrument of statecraft, is consequently entangled in these tensions between Spain on one side and Morocco, Israel, and the US on the other. “When a state perceives shifts in the regional balance of power, borders often become the first arena through which strategic messages are conveyed,” stated The Jerusalem Post. The changing balance of power in the region has led to Ceuta emerging as more than a border city. “[I]t is one of the places where the future balance of power between Europe, North Africa, and the Middle East is beginning to take shape.”

This isn’t the first influx of migrants from Morocco to Spain. In 2021, after Spain admitted the leader of a movement seeking independence for Western Sahara, Brahim Ghali, for COVID-19 treatment, Morocco relaxed border controls and roughly 8,000 people entered Ceuta over two days.

Spanish authorities labeled the move as “blackmail,” and as The New York Times noted at the time, “hours after the migrants began pouring into Ceuta, Spain approved 30 million euros, about $37 million, in aid to Morocco for border policing.” In 2022, Spain’s foreign minister was replaced, and Madrid reversed its longstanding position on Western Sahara, backing Morocco’s proposal. “Five years later, when a larger crossing occurred amid a different set of Spanish disputes, that structural vulnerability had still not been addressed. This does not mean 2026 repeated 2021’s mechanics. It means the vulnerability 2021 exposed was still there to be exploited, deliberately or not,” pointed out the Middle East Political and Economic Institute.

The latest crisis is far larger, and Spain is again negotiating with Morocco over migration and bilateral relations. But the consequences are not just for Spain. Although migrants arriving in Ceuta cannot automatically travel onward to mainland Spain or the wider EU, the enclave’s status makes these border crossings a European issue.

Italy and France quickly floated tighter border controls with Spain, drawing support from other EU members and pushback from Madrid. But their tensions mask a collective anxiety and frustration over irregular migration to the bloc and the growing ability to exploit the issue as a diplomatic tool.

The Roots of Europe’s Vulnerability

Governments have long viewed outward migration as a domestic safety valve for overcrowding, unemployment, and unrest. Britain transported convicts and political dissidents to its colonies, alongside
