The Flag, the Quinas 🛡️ & “A Portuguesa”
Issue No. 9 · Pillar 2: Culture and Nation- What every element of Portugal's flag and anthem means, and how they became the Republic's national symbols in 1911. 🛡️
New here? Welcome! We’re working-class travelers, history lovers, digital nomads, Portuguese residents, and many others — building the clearest guide to Portugal’s new citizenship exam (the TNIC) and learning about Portugal along the way, one issue at a time. It’s as much about getting to learn and really know and appreciate Portugal — its history, its customs, and culture — as it is about passing a citizenship exam.
If you’re learning about Portugal, preparing for residency or eventual naturalization — as I am — subscribe free as I prepare alongside you and we will walk through every TNIC exam topic, week by week.
If you are here just to Practice It there are three quick questions at the bottom, useful if you are prepping for the TNIC are wanting to test your current knowledge about Portugal.
The short version
Look at the Portuguese flag and you are reading a sentence the country wrote about itself in 1911 — three years before the First World War, one year after it stopped being a monarchy. Green where there had never been green. A medieval shield. A navigator’s instrument. And five small blue shields holding a thousand-year-old argument.
Article 11 of Portugal’s Constitution names the flag and the anthem by article — not by implication, but explicitly, by name. Under Lei Orgânica 1/2026, which governs the TNIC citizenship exam, knowledge of Portugal’s national symbols is a tested requirement. This is not soft culture; for the TNIC reader, it is examinable fact with clean hooks: two objects, a handful of dates, one decree.
For anyone living in Portugal, the flag flies on every public building on Sundays and holidays under Decreto-Lei 150/87. Insulting it in public is a crime under Article 332 of the Penal Code, punishable by up to two years. The symbols are protected the way the institutions are. For the civic-curiosity reader, the flag packs four centuries into one rectangle. By the end of this issue, you will be able to read every layer.
The Flag the Republic Built
The green-and-red combination was not ancient Portugal’s colors. Historic royal Portugal flew blue and white. The verde-rubro (green-and-red) scheme traces to the failed republican revolt of 31 January 1891 in Porto and was carried again at the Revolution of 5 October 1910 that ended the monarchy.
Ten days after the revolution, on 15 October 1910, the Provisional Government named a commission to design a national flag. Its members: the painter Columbano Bordalo Pinheiro, the writer Abel Botelho, and the journalist-politician João Chagas. The government approved the design on 29 November 1910.
Then, on 19 June 1911, the National Constituent Assembly issued the decree that made the flag official — the same decree, in the same act, that named “A Portuguesa” the national anthem. The detailed specifications for the flag’s proportions followed on 30 June 1911.
The flag was designed in 1910; it became law in 1911. Something to remember for the TNIC exam.
What the Sphere and the Shield mean
The commission did not leave its choices unexplained. In its own words, the Manueline armillary sphere — the navigator’s instrument in gold behind the central shield — is “the eternal standard of our adventurous genius” (padrão eterno do nosso génio aventureiro). It is a direct reference to the Age of Discoveries and the reign of Manuel I.
The white shield with five blue escudetes is the emblem “of the founding of the nationality” (da fundação da nacionalidade). The commission that built a new republic chose to keep its two oldest-looking elements — and told us exactly why.
The Quinas
The five small blue shields at the center of the Portuguese coat of arms are the quinas (singular: quina). Each carries five white bezants (besantes) arranged in a cross; the five shields themselves form a cross. Tradition ties them to the Lenda de Ourique — the founding battle of 1139, in which Afonso Henriques is said to have had a vision of the five wounds of Christ before defeating the Moors. Historians date the story to 15th- and 16th-century chronicles, not the 12th century. The legend came centuries after the fact.
The seven gold castles on the red border of the coat of arms are often misattributed to Afonso Henriques. They are not his. Castles were added to the coat of arms under Afonso III in the 13th century — a full century after Afonso Henriques — but the specific count of seven was not fixed until the second half of the 16th century, well after Afonso III’s reign.
“A Portuguesa” — a protest song that outlasted its target
“A Portuguesa” was not written as a celebration. Music by Alfredo Keil, lyrics by Henrique Lopes de Mendonça, it was written in early 1890 in direct response to the British Ultimatum of 11 January 1890 — London’s demand that Portugal abandon its claim to the territory between Angola and Mozambique (the “Pink Map”). The song became the march of the 31 January 1891 republican revolt in Porto. The monarchy banned it. The 1910 revolution revived it, and the 1911 decree made it the national anthem.
One more date: the anthem was adopted in 1911, but the official orchestral version was not fixed until 1957, by a Council of Ministers resolution published 4 September 1957 in the Diário do Governo, with the arrangement by Frederico de Freitas. The anthem existed for 46 years without an official musical version.
Denmark’s flag, and why the comparison matters
Portugal is not the only country whose flag carries a medieval miracle. Denmark’s Dannebrog — the world’s oldest national flag in continuous use — comes with its own founding legend: it fell from the sky during the Battle of Lyndanisse on 15 June 1219, turning a losing Danish crusade into victory. Modern historians in both countries treat the miracle as a later invention. The Dannebrog story appears first in 16th-century sources; the Ourique apparition in 15th- and 16th-century chronicles. Both stories were written centuries after the events they describe.
The instructive difference: Denmark built its entire flag on the legend. Portugal folded its legend into one corner — the five quinas — and surrounded it with datable history: Reconquista castles, a Manueline sphere, republican colors chosen in 1910. Denmark let the myth be the flag. Portugal made the myth one stanza of a longer, documented sentence.
