How the Portuguese State is organised: a fixed perimeter
Of the five civic themes named in the new law, this is the one people dread and the one with the clearest edges. The statute asks candidates to know «a organização política do Estado português» — the political organisation of the Portuguese State — and the Portuguese Constitution happens to contain a whole Part with almost that exact title: Part III, Organização do poder político, running from Article 108 all the way to 276. That is your syllabus, written by the State itself, and it is finite.
The short version, if you read nothing else: there are four organs of sovereignty; the President is elected for five years; parliament sits for a legislature of four legislative sessions; and nobody, anywhere, votes for the Prime Minister. If this is your first stop, read what the 2026 nationality law actually changed first and come back for the theme.
- There are four organs of sovereignty: the President, Parliament, the Government and the Courts — not three.
- Nobody votes for the Prime Minister: the President appoints one, taking the parliamentary election result into account.
- The Constitution fixes terms and calling rules, not dates — and it is always the President who sets election day.
- One single article lists what not even a constitutional revision can change about this State organisation.
One institutional point first
Nationality applications in Portugal are decided by the IRN — Instituto dos Registos e do Notariado, under the Ministry of Justice. AIMA handles residence permits, which is a different process with a different agency. The civic test belongs to the nationality track, so nothing in this article is AIMA's business. That confusion costs people wasted trips; it is unpicked in where you actually file a nationality application.
The adjective «political» is doing real work
Sub-paragraph (d) of the Nationality Act (Law 37/81, as amended by Organic Law 1/2026) requires applicants for naturalisation to «know sufficiently the fundamental rights and duties inherent to Portuguese nationality and the political organisation of the Portuguese State».
Two things are named, and the Constitution has two Parts with almost those names: Part I, Fundamental rights and duties, and Part III, Organisation of political power. Every article cited below is in that text, published by parliament — this guide is worth checking against it rather than taken on trust. The first half is covered in the article on fundamental rights and duties; this is the second half.
And note what the statute does not ask for. Not the administrative organisation of the State: no list of ministries, no social-security architecture, no public institutes. Only political power — who holds it, how they get there, and who answers to whom. If a study list has you memorising the names of government departments, it has drifted outside the statute.
Four organs of sovereignty, and the fourth is the one people drop
Article 110(1) is a single sentence: the organs of sovereignty are the President of the Republic, the Assembly of the Republic, the Government and the Courts. Four. English-speaking readers tend to answer three, because the three-branches formula is the one taught everywhere else — but that is a different idea, and the Portuguese Constitution is not using it.
The sentence that explains the whole system comes right after: the organs of sovereignty must observe «a separação e a interdependência» — the separation and the interdependence — established in the Constitution. Interdependence is the unusual word, and it is the reason the President appoints the Prime Minister, parliament can bring the Government down, and the President can dissolve parliament. Those are not exceptions to the design. They are the design.
Nobody votes for the Prime Minister
This surprises almost everyone who did not grow up in a parliamentary system, and it is checkable in one line. Article 187(1): the Prime Minister «é nomeado pelo Presidente da República, ouvidos os partidos representados na Assembleia da República e tendo em conta os resultados eleitorais» — appointed by the President, after hearing the parties represented in parliament and taking the election results into account.
So a legislative election elects members of parliament, and nothing else. The President appoints, is constitutionally obliged to consult and to weigh the result, and is not bound to any particular name. The remaining members of the Government are appointed by the President on the Prime Minister's proposal.
The counterweight comes a few articles later, nine words long in Portuguese: the Government is answerable to the President of the Republic and to the Assembly of the Republic. Two simultaneous lines of accountability — this is why Portugal is commonly classified as a semi-presidential system. Worth knowing, though, that the word «semi-presidential» appears nowhere in the Constitution: it is a label from constitutional doctrine, not a quotable constitutional term. What the text gives you is the substance — the Government answers to two bodies, not one.
«Which body makes the laws?» has three correct answers
Some preparation sites ask which body is Portugal's legislature and mark «the Assembly of the Republic» as the whole answer. The Constitution is richer than that: legislative acts are leis, decretos-leis and decretos legislativos regionais.
Three categories, three authors. Leis come from parliament, which may legislate on any matter not reserved to the Government. Decretos-leis come from the Government, on matters not reserved to parliament or under an express authorisation from it. Decretos legislativos regionais come from the legislative assemblies of the Azores and Madeira.
The honest answer is that parliament is the legislature proper, but not the only producer of legislative acts. This is not a technicality for you: the law that created this test is itself an organic law, one of the reinforced-value categories the Constitution names.
The election calendar is a set of durations, not a set of dates
No one can hand you «the dates of the next elections» as study material, because the Constitution does not fix dates. It fixes terms and the rules for calling a vote.
| Body | Term | How it is called |
|---|---|---|
| President | 5 years, no 3rd consecutive term | Elected in the 60 days before the previous term ends, by absolute majority; without one, a run-off within 21 days |
| Parliament | Maximum of 4 legislative sessions | The President may dissolve it (outside the 6 months after an election and the President's final six months); dissolution itself sets the new election, within 60 days |
Who sets the day is always the President — for presidential, parliamentary, European Parliament and regional assembly elections alike.
Two cross-cutting rules finish the picture. Direct, secret and periodic suffrage is the general rule for filling elective office, seats are allocated by proportional representation, and the Constitution goes as far as naming the formula — the d'Hondt highest-average method. And the same Constitution bans holding any political office for life.
A unitary State with two named exceptions
Right at the start of Part III, the Constitution says the State is unitary, and in the same breath requires it to respect island autonomy and the autonomy of local authorities. The next paragraph names the exceptions: the archipelagos of the Azores and Madeira are autonomous regions with their own political-administrative statutes and their own organs of government.
Portugal is therefore not a federation, and not a plainly centralised State either. Each autonomous region has two organs of its own: a Legislative Assembly, elected by universal suffrage under proportional representation, and a Regional Government answerable to it. The Regional Government's president is appointed by the Representative of the Republic, taking the election results into account.
Local government: two tiers that exist, one that needs a referendum
The Constitution names three categories of local authority on the mainland: freguesias (parishes), municípios (municipalities) and regiões administrativas (administrative regions). The autonomous regions have parishes and municipalities.
Here is the subtlety almost no study list catches. Administrative regions are provided for in the Constitution, but their actual creation is made conditional on a law and on a favourable vote by a majority of the electors taking part in a nationwide direct consultation. Being named in the Constitution and existing on the ground are two different things — and a well-written exam question would have to say which one it is asking about.
The internal shape of every local authority is the same: an elected assembly with deliberative powers, plus a collegial executive body answerable to it. The Constitution does not fix how long local mandates run; that is electoral-law territory.
The courts: an organ of sovereignty nobody elects
It is worth understanding why the courts sit in the same list of four, alongside the President and the Government. The Constitution says the courts are the organs of sovereignty with competence to administer justice in the name of the people. And, in eight Portuguese words: the courts are independent and subject only to the law.
Note what is singular about that. The Government is not elected either, but it answers politically to two other bodies; the courts are neither elected nor politically answerable to anyone — «subject only to the law». They are the only organ of sovereignty in that position, and it is the condition of their independence rather than a gap in the design. On structure, the Constitution says that besides the Constitutional Court there are the Supreme Court of Justice and the judicial courts, the Supreme Administrative Court with the administrative and tax courts, and the Court of Auditors. Note the phrasing: the Constitutional Court is a court, but it sits outside those categories — defined as the court specifically competent in matters of a constitutional-legal nature.
The part not even a constitutional revision can touch
If you take one article away from this page, take this one. It lists the material limits on constitutional revision — what any revising law must respect — and several of its paragraphs are exactly this theme: the separation and interdependence of the organs of sovereignty (j), universal direct secret and periodic suffrage together with proportional representation (h), the independence of the courts (m), the autonomy of local authorities (n), and the political-administrative autonomy of the Azores and Madeira (o).
Read backwards, Article 288 is the State's own list of what it considers non-negotiable about its structure. As a study-priority guide for an exam, it is hard to beat — and it pairs with the sentence that opens Part III: political power belongs to the people and is exercised under the Constitution.
A method that survives whatever the regulation asks
For each body, answer three questions. Exam questions on this theme rarely go beyond them:
- What is it and what does it do — the Constitution's «definition» articles are one sentence each: 120, 147, 182, 202.
- How does someone get there — direct election, appointment, or neither.
- Who do they answer to, and who can remove them.
None of the three requires memorising an article number. The numbers are here so you can check every sentence in this guide against the text of the Constitution — which is what you should do with any study material, this one included.
Know that for the four organs of sovereignty, the two regional organs and the two local ones, and you have covered the theme. Where each of the five ends is set out in our page on the five themes, and the multiple-choice format is worth a run in the free practice quiz.
