Thailand’s old name: a journey through the history and significance of Siam
July 5, 2025
When planning a trip to Southeast Asia, Thailand often lands at the top of the list. But before we start checking **where Thailand is on the world map** and throw ourselves into packing with thoughts of paradise beaches and insanely fragrant food, it’s worth pausing for a moment. **Follow the map** of this country and you’ll see more than just a tourist destination. Have you ever wondered where the country got its name from? Thailand’s **old name**, Siam, is more than just a **crossword** that we type in when we are looking for the answer to **five letters**. It’s a key that opens the door to a **history** full of pride, political pomp and twists that we rarely think about when ordering **thailand curry**. Understanding why **thailand’s** name has changed, who the **Thai** are and **what the people of Thailand** (or is it **Thai**?) are called, and whether we speak **Thai** or **Thai**, really changes the perspective. Is there a **Thai language**? The answer to that question is part of the story. Your **trip** to **Bangkok**, where the **capital of Thailand is** this very city, can take on a whole new and deeper dimension. It will be a journey far beyond the beaten path of **tourists**.
Siam – how was the historical name of the land of smiles born?

Every good story has a **beginning**, and the one with the name ‘Siam’ is as confusing and colourful as the history of the **kingdom** itself. This word, which has featured on maps around the world for hundreds of years, still arouses curiosity today. But before it became a global synonym for exoticism, its roots lay in the complex tangle of languages, cultures and relationships that shaped this corner of **Southeast Asia**.
Where did the word Siam actually come from: a tangle of theories
Well, exactly where did ‘Siam’ come from? Historians and linguists still argue about its origins today, which only adds spice to the matter. One popular theory is that it all started with the Sanskrit word śyāma (श्याम), which means ‘dark’ or ‘brown’. This would make sense as a reference to the skin colour of the **inhabitants** of these lands. But there are other hypotheses as well. One linking the name to Mon-Khmer languages, another to Chinese terms for peoples living in the **south**. Actually, viewed from another perspective, this lack of conclusive evidence is fascinating. The **origins** of the name remain in the realm of conjecture, making it an intriguing enigma of **national** heritage.
Who called the country Siam? A look from the outside and the inside
Most interestingly, the people of the kingdom themselves were unlikely to use the name Siam. It was a typical exonym – a name given to and used by outsiders (a bit like we say Italy, not Italia). From as early as the 12th century, Persian merchants, and after them the Portuguese, Dutch or French, in conducting their business and diplomacy, maintained **relationships** with this country, using this very term. And for the locals, i.e. the Thais? Their homeland was simply Mueang Thai (เมืองไทย), or in free **translation**, “Country of the Thais”. And it was this discrepancy between how others saw them and how they saw themselves that played an **important role** in the country’s subsequent tumultuous fate and eventual change of the banner. It was about showing the world who was the real host here.
How far back did former Siam go and what does it mean for us?
When we talk about **old Thailand**, we should not think of the ruler-sharp borders we know from modern maps. The extent of this kingdom fluctuated seamlessly, with its influence reaching areas of **today’s Thailand**, but also parts of **Cambodia** to the **east**, Laos, Burma and Malaysia. Its power grew with successive capitals. First there was **Sukhothai**, considered the cradle of the state and **located** in the **northern** part of the country, and then came the mighty **imperium** with its centre in **Ayutthaya**. This **former capital**, for over four hundred years, was one of the largest and richest cities in the world at the time, and its ruins, listed as a **UNESCO World Heritage Site**, are still colossally **impressive** today. It is worth **visiting** this huge **complex**, especially the famous **Wat Mahathat** temple, where you can **see** the famous **Buddha statue** in the roots of a tree. The **remains** of the **royal palace** and hundreds of other **temples** throughout the **area** bear witness to its former **luminosity**. Although it must be admitted that the romantic image of a powerful empire that deftly manoeuvred between neighbours is sometimes a little idealised. It is from this period that most of our associations with Siam originate, and the **old name of Thailand for crossbreeding** is often just ‘Siam’.
From Siam to Thailand – a political shift that shook the country

Giving up a name with such a long tradition is never an easy decision. In the case of Siam, the country that **formerly** was known by that name, it was a real revolution that echoed around the world and changed the perception of the kingdom forever. It was not a mere cosmetic change on the map, but a deeply considered **policy** and manifesto that would open a **totally** new chapter in the nation’s history.
A political storm: why did Siam have to disappear from the maps?
The key date was 24 June 1939. It was when the country’s Prime Minister, Field Marshal Plaek Phibunsongkhram, announced that Siam was officially becoming Thailand(Prathet Thai). The decision was part of a major nationalist and modernisation campaign to unite all ethnic groups under the common banner of ‘Thainess’. **The former name of the State of Thailand** – ‘Siam’, seen as too elitist and associated mainly with the centre of the country, had to go. And ‘Thailand’ was intended to be more capacious, emphasising the dominance of the Thai people, while at the same time providing a show of strength vis-à-vis the Western powers that were pushing ever harder into the region. However, the change did not pass smoothly. After the **Second** World War, in 1946, when the Phibunsongkhram government lost power, the country momentarily reverted to the name Siam. However, the return to **thailand’s previous name** proved to be temporary, because as early as 1949, after another military putsch, the name Thailand was restored and has remained so. This brief but intense tussle perfectly illustrates how the country’s name was linked to the struggle for its soul and identity.
‘Land of the free people’ – the symbolism hidden in the new name
The new name carried a huge symbolic charge. The word Thai (ไทย) in **Thai** means ‘free’ or ‘free man’. Thus, ‘Thailand’ is simply the ‘Land of the Free People’. Can you think of anything more proud? It is a direct reference to a fact that is the foundation of **national identity**: Thailand is the only country in the region that has never been a victim of European colonisation. This is a source of great pride, and the country’s name is a daily, resounding reminder of it. Every use of it is a silent tribute to the generations who managed to defend their sovereignty by showing great **respect** for their history.
Siam’s heritage today: where can the old name still be found?

Although maps have long shown **Taiwan**, the spirit of old Siam is not going anywhere. All it takes is a little attention and its traces can be found everywhere. Heritage is not just about names. It’s also about flavours and experiences: the famous **Thai food**, such as the aromatic **Thai curry** or the refreshing **Thai ice cream**, which can be tasted at every turn. It’s also a dynamic culture: spectacular **Thai boxing** (Muay Thai) or relaxing **Thai massage**. Even the globally popular drink **Red Bull** has its **Thai** roots. I remember on my first trip to **Bangkok** being shocked at how often the name “Siam” appeared in the most modern places, far more often than on restaurant signs serving **Thai food** in faraway **Warsaw**. The old name has not died, it has simply found a new life for itself in the heart of the modern kingdom.
Famous Siamese cats are more than just animals
Perhaps the world’s most famous symbol of ancient Siam are these beautiful cats with their distinctive colouring and mesmerising blue eyes that bring to mind the **Thai sky**. Siamese cats, locally known as Wichianmat, have been the real treasure of royal palaces for centuries. They were even believed to bring good luck and guard the souls of the dead. Today, these elegant pets are charming ambassadors of the former kingdom all over the world, reminding us of the historic name of the country from which they originated.
From shopping malls to universities: Siam is still alive in Bangkok
Walking around modern **Bangkok**, you will come across the name “Siam” at every turn. Really, you don’t have to look particularly hard – in the heart of the metropolis, where its commercial heart beats, you’ll find a whole **complex** of places that pay homage to its former glory. It is here, near the central BTS train station, that names reign supreme that every tourist, local and **tuk-tuk driver** knows well:
- Siam Paragon, Siam Center, Siam Discovery – luxury shopping malls that are synonymous with modernity, but proudly carry the historic name.
- Siam Square – a vibrant youth meeting centre, full of shops, pubs and trendy boutiques.
- Siam Kempinski Hotel – one of the most prestigious hotels in the capital.
- Chulalongkorn University – the oldest and most respected university in the country, founded back in the days of the Kingdom of Siam.
All these **attractions** and places are the best proof that Siam is not a relic, but a brand associated with prestige and identity that has found its way well into the 21st century.
Siam in pop culture and everyday life
Siam, with all its aura of exoticism and the richness of **Thailand’s culture**, has long worked its way into the imagination. In Western culture, the name has become synonymous with oriental luxury. We see it in the titles of films, books and games. Of course, the most famous example is the musical about an English governess in the court of the King of Siam. Even something as mundane as the question of **what language applies in Thailand** has its roots in this story. The **official language is Thai**, which has its own beautiful but complicated **Thai alphabet**. Fortunately, it is easy to communicate in **English** in tourist areas. Even so, it is worth learning the **basic phrases**, which is always met with great appreciation. It is also worth learning about **Thai names**, which often have deep, symbolic meaning, or finding out when the lavish **Thai New Year** falls. Even when planning your budget, you come into contact with your heritage by checking the current **currency exchange rate**, which is the **Thai bat** (or rather, the **Thai bats**). Thailand’s modern **capital city, Bangkok**, also has a fascinating history. Its **complete name** is one of the longest in the world, and a question about it even appeared on the TV quiz show **Millionaires**. The **Capital of Thailand in Thai** is Krung Thep Mahanakhon, and the city **was founded** on the **eastern** bank of the mighty Menam River (now known as the Chao Phraya). Looking at the **map**, we can see how vast this metropolis is. It is also interesting to see how **Thai women** are perceived – often as a symbol of gentleness and strength at the same time.
Siam versus Thailand – a history much deeper than a change on a map

The story of Siam’s transformation into Thailand is much more than a clerical formality and an answer to the question of what **thailand’s old name is in the crosshairs**. It is a story about the birth of a modern state, the search for one’s own identity and the pride that comes from being the ‘land of the free’. Understanding this process provides a different perspective on Thailand today – a country that cherishes its heritage with reverence on the one hand, and looks boldly to the future on the other. The next time you admire the golden **temples** in **Bangkok** or sample the local specialities, remember this dual identity. The **Thai of yesteryear** and today is a fascinating mix that **has** retained its unique **meaning**. In every Thai smile, in every name and monument, there is both the spirit of mighty old Siam and the pride of modern, free Thailand. And it is this duality that makes a trip there such an extraordinary experience.
