On July 30 and 31, 2026, Ceuta experienced an episode of exceptional magnitude. The Government of Spain maintains at 72,000 the figure of people who entered irregularly from Morocco. Most returned in a short time; weeks later, thousands remained there while identification and reception procedures continued.
Behind that number there are different biographies. Some may have left in search of work; another migrant, to reunite with relatives; a third, out of fear for their safety or imagining a different future. Their reasons, knowledge and plans are not necessarily the same.
Then arises another question, different from why a person emigrates: how can so many trajectories converge in a single place within such a brief interval?
The episode is too new for academic research to have established its causes. But Ceuta and the Spain-Morocco border have been under study for decades. Personal networks, mobile phones, and prior crises have allowed examination of how many choices can concentrate temporarily. To understand it, one must abandon a misleading intuition: a crowd is not simply a sum of strangers.
A crowd is not simply thousands of people gathered together
Before approaching those works, it is worth clarifying what a social network means here. We are not necessarily talking about Instagram, TikTok or Facebook, but about the web formed by family members, friends, acquaintances, travel companions and casual contacts.
Through these ties circulate practical help, experiences from those who have already made the journey, warnings about risks and news about routes, checks or possible opportunities to pass.
Imagine a station where no one knows the time of the next train. A traveler learns that a new path has just been opened and informs three acquaintances, and they pass the message on to others. Each person retains the power to decide whether to go to the platform, but a newly shared update gathers many choices around the same opportunity.
Not only social networks: among family, friends, acquaintances, travel companions, and casual contacts circulate help, experiences, warnings, and news for migration.
Migration, of course, is infinitely more complex than catching a train. The comparison illuminates only one mechanism: our decisions rarely originate in an informational vacuum. What we know, what we believe is possible, or what we consider dangerous depends in part on what we have learned from others. Information travels far faster than the people who receive it.
Researchers found networks where isolated decisions seemed to exist
Analyses of mobility linked to Ceuta and Melilla reveal the importance of these ties. The literature distinguishes between strong links — family members or close friends — and weak ties, such as someone recently known, a person encountered along the journey, or the contact of a contact.
The latter may seem less relevant, but they hold an advantage: they bring knowledge absent from the usual circle. Someone who traversed a given stretch before may know an accommodation, a risk, a route or an opportunity unknown to others. Thus, a fleeting relation can sometimes redirect the next step of a months- or years-long itinerary.
The choice remains personal, even though part of the elements used to take it come from a collective network.
None of this makes the individual into a piece dragged along by the group. The distinction is essential. The choice remains personal, even though part of the elements used to take it come from a collective network.
Near Ceuta, a phone can also become a compass
Miguel Fernández Labayen and Irene Gutiérrez observed sub-Saharan youths who remained in Moroccan settlements near the Spanish border while preparing the crossing. Through fieldwork, participation and interviews, they analyzed the videos they produced and the role those recordings played in their daily lives.
The difference matters. In an aerial photograph, the border seems made of fences, roads, checkpoints, breakwaters and water. For someone trying to cross, there exists another invisible layer: what they know about the terrain, where they perceive an obstacle, what happened to those who tried before, or when they believe circumstances have changed.
Another ethnographic study, focused on everyday mobility through Tarajal rather than on mass irregular entries, examined a WhatsApp group used to cope with uncertainties related to controls. It illustrates a broader idea: a border is also a space of information.
2021 showed how thousands of trajectories could converge
Five years before the 72,000 people entered Ceuta irregularly, the autonomous city had already endured another extraordinary episode. In May 2021, around 8,000 entered in about 36 hours.
During those events, messages and rumors circulated that the crossing had become accessible. In a connected population, such an expectation spreads quickly and alters when many people deem it viable to act.
Messages and rumors circulated that the crossing had become accessible, and in a connected population, such an expectation spreads quickly and alters when many people deem it viable to act.
Stopping there would be misleading. Material and political conditions also changed. The Moroccan controls ceased to function in the usual way during a period of strong diplomatic tension between Spain and Morocco. Later work has even analyzed that episode as a possible coercive use of migration within the confrontation.
There is therefore no equation like “rumor equals 8,000 entries.” Instead, a synthesis emerges: people already inclined or prepared to move, networks that carry knowledge, shared expectations, and an exceptional shift in the real possibilities of crossing.
When several elements coincide, many choices compress into a few hours. That does not mean everyone receives the same message or pursues the same objective. The academic literature offers something more cautious: it identifies mechanisms capable of favoring that a multitude of itineraries converge temporarily.
In 2026, misinformation returns to be part of the story
The present adds a particularly relevant piece. Following the arrivals on July 30 and 31, the Spanish government warned of messages broadcasting a mistaken interpretation of a Supreme Court ruling about those who enter by sea. The Ministry of Foreign Affairs had to publicly clarify that entering Ceuta or Melilla irregularly does not grant the right to stay in Spain, travel to the Peninsula, or circulate through Europe.
Interior also maintained that trafficking networks were instrumentalizing that judicial ruling to promote the flow. They are institutional claims about recent events, not a scientific demonstration that those messages caused the 72,000 entries.
That distinction is crucial. Prior evidence helps explain why true, false, or incomplete information spreads rapidly within connected populations and reshapes the perceived opportunity. Nevertheless, it still does not allow calculating how much weight that process carried in July 2026 or separating it from other factors.

A border can change without moving an inch
We tend to imagine a border as a line on the map, a fence, or a guard post. Yet its permeability can transform without anything physical moving. New rules, different inspections, required documentation, or administrative decisions are enough.
Ana López-Sala, from the CSIC, and Dirk Godenau, from the University of La Laguna, have approached Ceuta, Melilla and the Canary Islands through the concept of transferability. The term describes, in simple terms, to what extent someone who has reached one of these territories can continue afterward toward other places, the Peninsula.
The idea breaks a straightforward intuition: reaching Spanish soil does not necessarily mean finishing crossing the relevant borders for the journey. Ceuta has a special regime and there is subsequent supervision to move toward peninsular territory.
Another ethnographic study, centered on the everyday mobility through Tarajal and not on large irregular entries, examined a WhatsApp group used to confront uncertainties related to controls. It illustrates a broader idea: a border is also a space of information.
What studies can and cannot explain about Ceuta in 2026
The recent situation invites us to ask whether the mechanisms documented above have reappeared. Asking that question is legitimate; answering affirmatively without investigation would not be.
A study of 2005 or 2021 does not prove the causes of what happened in July 2026. Nor does it authorize observing a crowd and concluding that a rumor caused it, that WhatsApp synchronized its movements, or that all its members reacted to the same stimulus. Each event gathers its own political, social, economic and personal circumstances.
The situation continues to evolve. On August 27, Interior reinforced the triage device — the initial identification and evaluation of people who remain in the city — and the minister of the Interior appeared the next day in Parliament. According to the figure announced then, about 5,000 were still in Ceuta.
Each event brings its own political, social, economic and personal circumstances.
What Ceuta teaches us about human decisions
The lesson goes beyond a city and a crisis. We tend to explain collective behavior by first imagining individuals acting independently and then summing them up. At the other extreme, a crowd may seem like a single-willed entity. No single image adequately captures what these investigations reveal.
Each person decides within changing relationships, knowledge and circumstances. News transmitted by someone trusted, someone else’s experience, a newly perceived opportunity or an objective change in the environment alters the options available. That does not erase individual autonomy: it redefines the stage on which it is exercised.
Therefore, the Ceuta of 2026 acquires deeper meaning: they do not show a single mass or tens of thousands of disconnected points, but rather they portray different biographies whose paths end up coinciding when information, ties, expectations and border conditions interweave.
To understand why this happens, each case requires its own investigation. But the accumulated evidence has already renewed something essential in our view: when thousands of people reach the same place at the same time, what we see is the crowd; much of the explanation lies in the invisible bridges that connect its members.
