Portugal’s history is rich with fascinating stories, some true and others embellished over time. We can assure you: all of the myths listed below are things we have been told by local Portuguese! Let’s examine six widely circulated claims about Portugal and separate fact from fiction once and for all.
Myth #1: Portugal invented the guitar and spread it around the world.
Fiction
While Portugal has its own unique instrument called the Portuguese guitar (guitarra portuguesa), it did not invent “the guitar” in the general sense. The Portuguese guitar is a 12-string instrument descended from the medieval citole and was developed through a fusion of the European cittern and the English guitar, which was introduced to Portugal through the British trading post in Porto during the 18th century. This specialized instrument is primarily associated with fado music and remains distinctly Portuguese.
The modern six-string guitar that became popular worldwide has different origins entirely. The guitar’s evolution involved many cultures across centuries, with the Spanish guitar maker Antonio de Torres Jurado creating what became the standard classical guitar design in the mid-1800s. The guitar’s roots trace back through Spanish vihuelas, Moorish instruments, and even ancient Greek and Roman stringed instruments.
Portugal did, however, contribute the ukulele to the world. Portuguese immigrants from Madeira brought small stringed instruments called the machete (or braguinha) and the rajão to Hawaii in the 1870s, which directly inspired the creation of the ukulele.

Myth #2: Portugal was responsible for making tea popular in the UK.
Mostly Fact
This claim is essentially true. When Catherine of Braganza, a Portuguese princess, married King Charles II of England in 1662, she brought with her a chest of tea from Portugal. The Portuguese had been importing tea from China since the early 1550s through their trading post in Macau, which made Portugal one of the first European nations to develop a taste for the beverage.
Tea had technically reached England before Catherine’s arrival, but it remained a rare medicinal curiosity sold in apothecary shops. Samuel Pepys recorded his first taste of tea in 1660. He described it as a “China drink” he had never tried before. Catherine transformed tea from an exotic medicine into a fashionable social beverage. As queen, her daily tea-drinking habits were closely observed and imitated by ladies at court, who then spread the custom through aristocratic circles.
Catherine’s influence went beyond making tea consumption popular. She introduced the concept of tea as a social ritual instead of a medicinal tonic, and her preference for drinking it with milk established what would become a distinctly British tradition. While Catherine didn’t technically “introduce” tea to England, she absolutely made it popular and fashionable, which fundamentally changed British culture. Thus, this myth is substantially true.

Myth #3: Christopher Columbus was born in Cuba, Portugal.
Fiction
The vast majority of historians agree that Christopher Columbus was born in Genoa, Italy, around 1451 to a wool merchant named Domenico Colombo. Contemporary documents from Genoa and Savona support this consensus, and Columbus’s Genoese origin was not controversial during his lifetime.
However, there is a small Portuguese town called Cuba in the Alentejo region, and since the 20th century, a handful of scholars have promoted the theory that Columbus was actually Portuguese, born in this town. Proponents of this theory, such as José Mascarenhas Barreto in 1988, suggested Columbus was really Salvador Fernandes Zarco, a Portuguese agent who deceived the Spanish. They point to the fact that Columbus named the Caribbean island “Cuba” as potential evidence of his birthplace.
The Portuguese theory also notes that Columbus’s wife, Filipa Moniz Perestrelo, was Portuguese, and that he spent considerable time in Portugal before his voyages. Some have analyzed his signatures and writings for clues to Portuguese origin.
Despite these alternative theories, the evidence overwhelmingly supports Columbus’s Italian birth. The Cuban, Portugal connection remains an interesting local legend but lacks the historical documentation to overturn centuries of accepted scholarship. The town of Cuba even has a statue honoring Columbus, but this represents local pride more than historical fact.

Myth #4: The Japanese word for “Thank You” (arigatou) comes from the Portuguese “obrigado” after the Portuguese landed in Japan in 1543.
Fiction
Despite the striking phonetic similarity between the Japanese arigatou and the Portuguese obrigado, this is a false cognate. The resemblance is purely coincidental.
Historical records definitively prove that arigatou predates Portuguese contact with Japan. The word appears in Japanese literature from the 8th century in its original form “arigatashi,” which meant “difficult to exist” or “hard to be.” Over time, it shifted in meaning to “rare, special,” and then to “welcome, thankful, nice to have” by the 15th century. The Portuguese did not arrive in Japan until 1543, well over a century after arigatou was already being used to express gratitude.
The word arigatou comes from two Japanese roots: “aru” (to exist) and “katai” (difficult), conveying the idea that the favor being acknowledged is “something precious that rarely exists.”
While the Portuguese did introduce many loanwords to Japanese during the 16th and 17th centuries (including words like tempura, pan for bread, and tabako for tobacco), arigatou is not among them. The early Japanese-Portuguese dictionary compiled by Jesuit missionaries, the Vocabvlario da Lingoa de Iapam, lists “arigatai” with its derivative form “arigatou,” confirming the word existed independently before linguistic borrowing from Portuguese occurred.

Myth #5: King Dom Sebastião, who disappeared in battle in 1578, will return to save Portugal in its darkest hour.
Legend, but culturally true as a belief system
This myth forms the foundation of Sebastianism (Sebastianismo), one of Portugal’s most enduring cultural phenomena. King Sebastian of Portugal led a disastrous crusade to Morocco in 1578, where his army of 17,000 men was crushed by a superior Moroccan force of over 60,000 at the Battle of Alcácer Quibir on August 4, 1578. Sebastian, only 24 years old, was almost certainly killed in battle, though his body was not immediately recovered, which led to uncertainty about his fate.
The young king had been called “O Desejado” (the Desired One) even before his birth, and after his death, many Portuguese refused to believe he was truly gone. When his body was eventually returned to Portugal in 1582 and interred in the Jerónimos Monastery in Belém, his tomb was inscribed with a verse that translates to: “In this tomb lies buried Sebastian, if the story is true.”
The legend of Sebastian’s return became a powerful messianic belief. According to Sebastianism, the king is “O Encoberto” (the Hidden One) who will return on a foggy morning to save Portugal in its darkest hour and establish the Fifth Empire, a spiritual kingdom of peace and prosperity. This belief gained particular strength during 1580-1640 when Spanish kings occupied the Portuguese throne, as people yearned for a deliverer to restore independence.
The myth has had remarkable cultural staying power. Between 1584 and 1598, at least four impostors claimed to be the returned Sebastian. The belief spread to Brazil, where it influenced messianic movements in the 19th century. The renowned Portuguese poet Fernando Pessoa built upon Sebastianist themes in his epic work “Mensagem,” and the legend inspired the 1968 song “A Lenda d’El Rei D. Sebastião” by Quarteto 1111.
Thus, while Sebastian will not literally return, Sebastianism remains a genuine and influential belief system in Portuguese culture, which represents the enduring hope for national renewal and redemption. The myth is fiction in the literal sense but very real as a cultural and psychological phenomenon.
Myth #6: Portugal had its own unique dinosaurs.
Fact
Portugal absolutely had its own unique dinosaur species, and the country is one of Europe’s most important dinosaur fossil sites. The town of Lourinhã is even known as “Dinosaur Town” because of the extraordinary number of fossils discovered there. Portugal’s Late Jurassic period, around 150 million years ago, was home to a rich ecosystem of dinosaurs, many of which are found nowhere else on Earth.

Several dinosaur species are endemic to Portugal or were first discovered there. Lourinhanosaurus antunesi, described in 1998, is a carnivorous theropod dinosaur named after the town of Lourinhã where it was found in 1982. This mid-sized predator, measuring about 4.5 meters long, is particularly significant because it was the first theropod discovered with gastroliths (stomach stones), and fossils include a nest with over 100 eggs, with some containing well-preserved embryos.
Lusotitan atalaiensis is another Portuguese endemic species. This enormous sauropod, originally classified as a species of Brachiosaurus when discovered in 1947, was recognized as its own distinct genus in 2003. The name combines “Luso” (referring to Lusitania, the ancient name for Portugal) with “Titan” from Greek mythology. This giant herbivore could reach up to 25 meters in length and represents one of the largest dinosaurs ever found in Europe.

The Lourinhã Formation has yielded numerous other significant finds, including species like Dinheirosaurus lourinhanensis, Dracopelta (an armored dinosaur), and various other theropods and sauropods. In 2022, a homeowner in Pombal accidentally discovered what may be one of Europe’s largest dinosaur skeletons in his backyard, an 82-foot-long sauropod with remarkably preserved ribs still in their original anatomical position.
Portugal’s dinosaur fossil record is so rich that paleontologists compare the Lourinhã Formation to North America’s famous Morrison Formation. The Portuguese Late Jurassic ecosystem was a semi-arid floodplain environment where multiple large predators like Allosaurus, Torvosaurus, and Ceratosaurus competed alongside the endemic Portuguese species. This makes Portugal not just a country with unique dinosaurs, but one of the world’s premier locations for understanding Late Jurassic dinosaur diversity and evolution!
Conclusion
Of these six myths, two are substantially true: Catherine of Braganza popularizing tea in Britain and Portugal having its own unique dinosaurs. Three are complete fiction (the guitar’s origin, the arigatou etymology, and Columbus’s Cuban birthplace), and one exists in an interesting space between legend and cultural reality (Sebastianism).
