European rule began with conquest.
Portugal captured Ceuta in 1415 from the Marinid sphere. Spain was not the conquering state.
The facts behind a deceptively simple argument
Is Ceuta a colony?
European rule began with conquest. Spain’s claim was later consolidated by treaties, administration and constitutional integration. Morocco calls the city unfinished decolonisation. The people who live there are Spanish citizens with self-government. No slogan contains all four facts.

Why the argument returned
A border emergency made an old sovereignty dispute newly visible.
On 30–31 July 2026, local Spanish officials estimated that about 60,000 people entered Ceuta from Morocco. On 1 August, Spain raised the confirmed death toll to 67. The episode concerns migration, border control and humanitarian responsibility. It does not, by itself, answer who has title to the territory.
Before taking a side
Seven facts the argument has to survive.
The debate becomes much clearer once chronology, present government and international status are separated.
“Spanish since 1415” is false shorthand.
Ceuta became connected to the Spanish crown during the Iberian Union. After Portugal restored its independence, the city remained with Spain.
Portugal recognised the outcome in 1668.
The Treaty of Lisbon recognised Portuguese independence while leaving Ceuta with the Spanish crown. Later Spain–Morocco treaties also dealt with its perimeter.
Ceuta was not transferred when Morocco became independent.
In 1956 Spain ended its protectorate in northern Morocco, but treated Ceuta as separate Spanish territory. Morocco regarded that separation as unfinished decolonisation.
Ceuta is constitutionally integrated into Spain.
Since 1995 it has had the status of an autonomous city. Its residents participate in Spanish political institutions and are not governed as colonial subjects without citizenship.
Morocco has not accepted Spanish sovereignty.
Morocco officially calls Sebta Moroccan territory. Spain officially answers that Ceuta is under its full sovereignty.
The UN does not put Ceuta on its decolonisation list.
Ceuta is absent from the current list of Non-Self-Governing Territories. That weakens claims of an internationally settled decolonisation status, but it does not amount to a judicial ruling that Spain owns the city.
How the status was built
Ceuta did not simply become “Spanish in 1415”.
Portugal conquered the city. Spain inherited and consolidated the position later. Morocco’s independence then supplied a new decolonisation argument.
1415
Portugal captures Ceuta
A Portuguese expedition takes the city from the Marinid sphere. This begins continuous European rule.
Why this mattersThe origin is colonial conquest—but Portugal, not Spain, is the actor.
The word doing too much work
“Colony” can mean three different things.
People often appear to disagree about facts when they are actually using different definitions.
A historical description
Was foreign rule established through imperial expansion, conquest or settlement? On this meaning, Ceuta’s European rule is plainly colonial in origin.
A formal decolonisation status
Is the territory treated by the United Nations as a Non-Self-Governing Territory? Ceuta is not on the current UN list. That is institutionally important, but not a court judgment.
A political claim
Does a neighbouring state and part of the public regard the territory as foreign occupation? Morocco does, and has maintained the claim for decades.
The evidence, lens by lens
So, is Ceuta a colony?
The answer changes with the question. Each lens isolates a distinction required by the evidence.
How European rule began
Colonial in originA maritime empire conquered a North African city and held it as part of overseas expansion. There is little serious basis for denying the colonial character of the origin.
Evidence strength: high
How it is governed today
Not a conventional colonyCeuta has an autonomy statute, representation and Spanish citizenship. It is not administered as a dependency whose inhabitants lack metropolitan political rights.
Evidence strength: high
How the UN treats it
Not formally on the decolonisation listUnlike Gibraltar, Western Sahara and the Falklands/Malvinas, Ceuta is not listed as a Non-Self-Governing Territory. This is an institutional fact, not a sovereignty judgment.
Evidence strength: high
Whether sovereignty is uncontested
No: Morocco maintains a claimThe two governments have placed opposing sovereignty declarations in the UN treaty record. Practical control and most international dealings favour Spain; political contestation remains.
Evidence strength: high
The most defensible description
Ceuta is a Spanish-administered autonomous city in North Africa, acquired through conquest and later consolidated by treaty and continuous administration, claimed by Morocco as unfinished decolonisation, and inhabited by Spanish citizens whose political preferences cannot simply be erased. Calling it “obviously illegal” goes beyond what international law has settled. Calling it “not colonial at all” goes beyond what the history permits.
The strongest version of each position
What Spain can prove. What Morocco can prove.
A fair account should strengthen each side before showing where its argument stops.
ES
Spain’s strongest case
What the evidence supports
- Portugal recognised Ceuta remaining with the Spanish crown in 1668.
- Spain and Morocco later concluded treaties defining and enlarging the city’s perimeter.
- Spain has exercised continuous administration for centuries.
- Ceuta is constitutionally integrated and its residents possess Spanish political rights.
- The UN does not place Ceuta in its formal decolonisation list.
What it does not prove
- It does not erase the fact that European possession began through imperial conquest.
- Domestic constitutional law cannot by itself decide an international claim.
- Long control is not identical to uncontested acceptance when Morocco has kept objecting.
MA
Morocco’s strongest case
What the evidence supports
- Ceuta is a European-held territory on the North African coast acquired through conquest.
- It was not transferred when colonial protectorates in Morocco ended in 1956.
- Morocco has consistently framed the issue as territorial integrity and unfinished decolonisation.
- The colonial context of nineteenth-century treaties complicates claims that every settlement was freely made.
What it does not prove
- Geographical proximity is not, by itself, a legal title.
- The modern Moroccan state is not automatically the legal successor to every dynasty that once influenced Ceuta.
- The claim must account for centuries of later treaty practice, administration and the rights of present residents.
- The UN has not formally classified Ceuta as a Non-Self-Governing Territory.

Useful comparisons, used carefully
Ceuta is not Istanbul, Gibraltar or Western Sahara.
A comparison helps only when we state both the similarity and the difference.
Gibraltar
What is similar
A European-controlled territory at the same strait, claimed by a neighbouring state.
What is different
Gibraltar is on the UN decolonisation list and its treaty has an explicit reversion clause involving Spain.
What the comparison teachesGeographic symmetry does not create legal symmetry.
Western Sahara
What is similar
Morocco frames both questions through territorial integrity and decolonisation.
What is different
Western Sahara is formally listed by the UN as a Non-Self-Governing Territory, and the ICJ held that historical ties did not displace self-determination.
What the comparison teachesThe UN decolonisation category is not inferred from geography; it is institutionally specific.
Hong Kong
What is similar
A long period of European control began through unequal nineteenth-century arrangements.
What is different
Britain and China negotiated a registered bilateral transfer for 1997. Spain and Morocco have no equivalent settlement over Ceuta.
What the comparison teachesLong administration can end when the states concerned reach a new agreement.
Goa
What is similar
A centuries-old Portuguese enclave was described by the surrounding postcolonial state as unfinished decolonisation.
What is different
India used force in 1961 and Portugal later recognised Indian sovereignty. Neither event has an equivalent in Ceuta.
What the comparison teachesA similar colonial argument can lead to a different outcome through force and later recognition.
Istanbul
What is similar
Its present sovereignty also has a medieval conquest in its historical chain.
What is different
The Ottoman Empire ended, modern Turkey emerged through war and treaty, and Greece does not maintain a current sovereignty claim to the city.
What the comparison teachesThe origin of control is only one part of a modern title.
The legal structure in plain language
Why history does not automatically settle a border.
International law preserves many coercively created borders while refusing to legalise new conquest. That tension is deliberate.
01Old conquest is not judged by today’s law alone+
The legality of an act is first assessed under the law of its time. Later conduct, treaties, recognition and administration then matter too. This is why the 1415 conquest is historically central but not the whole legal analysis.
Legal term: intertemporal law02New conquest cannot create lawful title+
Since the UN Charter order, territory acquired through unlawful force cannot be recognised as legal. That is why Crimea and Northern Cyprus raise very different legal issues from a medieval conquest.
Legal term: non-acquisition of territory by force03Treaties and state succession change the chain+
Ceuta passed from Portuguese conquest to Spanish rule through dynastic union, state separation and a treaty settlement. A modern claim cannot simply skip those steps.
Legal term: state succession and treaty title04Self-determination matters, but does not apply itself+
The wishes of a population matter greatly. The difficult question is whether the current residents constitute the decisive people, or whether decolonisation is owed to a larger territorial unit. Different disputes answer that differently.
Legal term: self-determination and territorial integrityWhat the facts allow us to say
Colonial history is not the same thing as colonial status.
Ceuta’s origins are colonial. Its present institutions are not those of a conventional dependent colony. Spain has the stronger position in effective administration and treaty-based title; Morocco has a real, persistent decolonisation claim rooted in geography and the history of European expansion. The dispute survives because those truths do not cancel one another.
