While Thailand is one of the few countries in the world that has never been colonised, it hasn’t always been Thailand. Before it became known as Thailand in 1939, it was called Siam. And before it became Siam, it was a collection of city-states, or smaller kingdoms, as Germany and Italy were in Europe. The northwesternmost of these smaller ‘Thai’ kingdoms was known as Lanna (or Lan Na) and it encompassed modern-day Chiang Mai and Chiang Rai as well as areas that are now part of China, Myanmar, and Laos. 

The Lanna Kingdom’s roots can be traced back to the 13th century; after centuries of autonomy and a long period under Burmese control, it was liberated by King Taksin in 1775 before eventually being fully integrated into Siam in 1892. Visitors to modern-day Thailand can explore the history and heritage of the Lanna Kingdom by journeying along the Lanna Kingdom route through northwestern Thailand, soaking up Lanna culture and visiting a Lanna Kingdom temple or two along the way. Read on to take a voyage through the region’s history and culture, and find out how you can still experience the essence of its former glory today.

What Was the Lanna Kingdom?

At its zenith, the Lanna Kingdom covered much of the Southeast Asian region known in modern parlance as the Golden Triangle. While the ancient kingdom’s borders were more fluid than present-day political borders tend to be, Lanna encompassed much of modern Thailand’s northwestern region – including Chiang Rai and Chiang Mai – as well as parts of contemporary Laos, Myanmar (formerly known as Burma), and the southern reaches of China’s Yunnan province.

The historical kingdoms throughout this region were similar to modern-day city-states, although there was a much less rigid demarcation of their boundaries. Instead, politics operated under what historians now refer to as ‘the mandala model’. Under this system, power radiated from a central hub – which in the case of the Lanna Kingdom was Chiang Mai – but influence waned the farther from the hub one travelled.

Places close to Chiang Mai, such as Lampang, would have very much been under the influence of the rulers of the Lanna Kingdom, whereas places farther away, such as those in modern-day Burma’s Shan State or Yunnan in China, would have felt somewhat less subject to the control of Chiang Mai’s radiating power. Indeed, these more far-flung reaches of the Lanna Kingdom may also have felt the authority of other power hubs to their north or west that were a similar distance away as Chiang Mai was. The ancient cities of Chiang Rung and Kengtung, for example, may well have also been paying tributes and taxes to power hubs in China and Burma respectively.

Where Was the Lanna Kingdom?

Nowadays, it is very easy to see borders as lines drawn on maps, much to John Lennon’s chagrin. But unlike in the heyday of the Beatles and the present day, at the height of the Lanna Kingdom’s influence, maps were still in their infancy and would have been seen only by the ruling elite and their war generals. Borders weren’t marked by barbed-wire-topped fences, but by natural boundaries and sporadic fortifications.

Yet modern references can give us a much clearer picture of the extent of the Lanna Kingdom. Thailand today is divided up into seventy-seven provinces (including the Special Administrative Region of Bangkok). If you are looking at an up-to-date map of Thailand, the extent of the Lanna Kingdom covers the upper eight provinces of the country: Chiang Mai, Chiang Rai, Lamphun, Lampang, Phrae, Nan, Phayao, and Mae Hong Son. Present-day tourists driving the Mae Hong Son Loop; tucking into a delicious khao soi gai in Old Town Chiang Mai; wandering among the old streets of Lampang; or admiring the former home of the Emerald Buddha at Wat Phra Kaew in Chiang Rai, will be standing on what was once Lanna Kingdom soil.

As already mentioned, the domain of the Lanna Kingdom extended beyond the modern-day Thai borders. It also extended into Laos, Burma and China. It would have incorporated the northwestern corner of Laos, and in Burma, the Lanna influence extended into the eastern regions of Shan State. To the northeast of Shan State, it would also extend into the southern areas of Yunnan. 

This region of Yunnan is known as Xishuangbanna Dai Autonomous Prefecture today: a name that originated from the Tai Lue name Sipsongpanna. This Tai Lue name means 12,000 rice paddies, and Lanna Kingdom means the ‘Kingdom of a million rice paddies’. In Thai, pan na means ‘1,000 rice paddies’, and this used to be a unit of land division in the region, before the French brought their metric system to the region. This linguistic link gives you a rough scale of how much the Lanna kingdom crept into modern-day Yunnan.

At the time of its existence, before maps became widespread, most of the Lanna Kingdom’s borders were fixed by natural boundaries. The kingdom flourished along four rivers and their respective basins. The rivers – the Ping, Wang, Yom, and Nan – flowed through valleys between the region’s mountain ranges. The rivers provided water for the settlers and their crops, while the mountains provided obstacles for neighbouring kingdoms’ armies, should they look to attack. The four rivers are all tributaries of the Chao Phraya River which, after they have all converged, continues to flow through the centre of Thailand, through Ayutthaya, and empties into the Gulf of Thailand. Its delta region is modern day Bangkok.

A brief history of the Lanna Kingdom

Before Lanna: the Mon Kingdom of Hariphunchai (c. 750–1281)

The 500 years that preceded the Lanna Kingdom’s rise saw the region ruled by Mon people as the Hariphunchai Kingdom. This kingdom dominated the Ping River basin and was centred around modern-day Lamphun. The Hariphunchai Kingdom was founded in the 8th century by Queen Camadevi, a princess from the southern Dvaravati civilization, and it went on to become the cultural and religious hub of Northern Thailand. The Mon people of the kingdom introduced Theravada Buddhism, written script, advanced irrigation, and refined brick architecture to the region. 

Mangrai and the founding of Chiang Mai (1262–1355)

In the latter half of the 13th century, King Mangrai set out to unify the scattered northern principalities into a single realm. After founding Chiang Rai in 1262, Mangrai set his sights on the wealthy Mon stronghold of Hariphunchai, finally overcoming it in 1281. Mangrai’s next move was to establish another new city to be his capital. Under the shadow of Doi Suthep (Mount Suthep) and within the fertile Ping River basin, King Mangrai founded Chiang Mai in 1296. The name ‘Chiang Mai’ means ‘new city’, and it was fortified with moats and walls. King Mangrai then forged alliances with neighbouring Tai rulers, established legal codes, and laid the political foundation for the Lanna Kingdom to flourish into.

The golden age of Lanna (1355–1558)

By the mid-fourteenth century the Lanna Kingdom was well established. The Lanna Kingdom had expanded its territory into parts of modern Myanmar, Laos, and southern China while holding off invasions from the southern Siamese Kingdom of Ayutthaya. Chiang Mai blossomed into a major Theravada Buddhist scholarship centre, hosting the Eighth World Buddhist Council in 1477. Monumental temples like Wat Chedi Luang and Wat Phra Singh were constructed, and Lanna bronze casting, literature, and temple architecture achieved unmatched artistic heights, funded by a flourishing agrarian economy and lively regional trade networks.

Two centuries under Burmese rule (1558–1775)

Weakened by internal dynastic disputes, the Lanna Kingdom became vulnerable, leading to its conquest in 1558 by King Bayinnaung of the Burmese Taungoo Dynasty. For over two hundred years, the kingdom existed as a heavily taxed vassal state and frontline military buffer zone. Burmese garrisons controlled local northern princes, using the region’s resources to fuel endless wars against Ayutthaya. Decades of heavy taxation, forced labour, rebel uprisings, and retaliatory invasions devastated the countryside. Major cities were repeatedly sacked and depopulated, reducing the once-glorious “Kingdom of a Million Rice Fields” to an impoverished, shattered shadow of its former pomp. 

Kawila, Siam and the end of Lanna (1775–1939)

In 1775, Prince Kawila of Lampang formed an alliance with King Taksin of Siam to drive the Burmese out of the north. Kawila is also credited with the resurgence of Chiang Mai at this time. He rebuilt the city and sought to bring the people back. He also found ways to restore its trade and agriculture. While the Lanna Kingdom was able to regain its cultural identity, its autonomy would continue to wane. It had become a tributary state under the Bangkok-based Chakri Dynasty. Over the next century, Siam gradually took over political power in Lanna, so much so that by 1899, Lanna was incorporated into Siam’s provincial system. When Chiang Mai’s last titular prince, Chao Kaew Nawarat, died in 1939, the ruling dynasty was officially phased out, formally integrating Lanna into modern Thailand.

Where to see the Lanna Kingdom today

Chiang Mai

As the former capital of the Lanna Kingdom, you may expect Chiang Mai to hold many examples of the kingdom’s architecture and history. And you would be right! At the heart of the city – northern Thailand’s largest city – you can still see remnants of King Mangrai’s walled city and its surrounding moat. Many of Thailand’s best ancient temple sites are located within former Lanna Kingdom boundaries. Chiang Mai boasts a few notable ones to visit: 

• Wat Chiang Man, built to the orders of King Mangrai himself, is the oldest in the city.
• Wat Chedi Luang, ‘temple of the grand stupa’, once housed the Emerald Buddha;
• Wat Phra Singh, which is known for its Lanna-era murals that depict ancient court life and local attire. 

Chiang Mai is also home to the Lanna Folklife Museum which offers insights into traditional Lanna crafts, textiles, and court rituals.

Lamphun

Lamphun sits a short, thirty-minute drive south from the centre of Chiang Mai. It is much smaller and quieter than the former capital, yet it retains some sites of interest for those checking out Lanna Kingdom history. Its city walls – oval-shaped, rather than square – are in better condition than the walls in Chiang Mai Old Town. Lamphun also has worthwhile temple sites to visit. 

The town was the former capital of the Lanna Kingdom’s predecessor, the Hariphunchai Kingdom, and the impressive Wat Phra That Hariphunchai is a must-see. The temple is believed to be from the 11th century, but it is thought that the main stupa predates this by around 200 years.

Lampang

The city of Lampang lies in the valley of the Wang River, bordered by the Khun Tan mountains in the west and the Phi Pan Nam range to the east. The river, a major tributary of the Chao Phraya, flows through the city. Wat Phra That Lampang Luang was founded in the 15th century and is seen as a prime example of a Lanna-style temple. Towards the end of the Burmese rule over the Lanna Kingdom, a famous local marksman – Nan Thipchang – assassinated the local Burmese leader in the temple. Wat Sri Chum and Wat Phra Kaeo Don Tao are also notable examples of Lanna-era temples, and they both feature multi-tiered pyat-that roofs which are evidence of the Burmese influence at the time of their constructions.

Chiang Saen and Chiang Rai 

The city of Chiang Saen was founded in 1329 by a grandson of King Mangrai. It is thought to be built on the site of a former city which was known as Ngoenyang. The city sits on the southern banks of the Mekong River, which today forms the Thai border with Laos. Visitors here should be sure to check out Wat Pa Sak. It’s an incredible site, home to 13th-century ruins which are surrounded by teak trees. The site  showcases Sukhothai, Pagan, and Hariphunchai architectural blends on its stucco stupa. 

Chiang Rai is also an important stop on the Lanna kingdom route. The city’s Wat Phra Kaew is where the Emerald Buddha was first discovered in 1434, thanks to a lightning strike to one of its chedis. Following the discovery, the temple (which was known as Wat Pa Yia at the time) changed its name to Wat Phra Kaew. The Buddha now resides at the Wat Phra Kaew temple within the Grand Palace complex in Bangkok.

Nan and Phrae

Nan is located almost due east of Chiang Mai, closer to the Thai/Laos border, and Phrae is somewhat in between the two. By the end of the 14th century, Nan was one of the nine northern Tai-Lao city-states that made up the Lanna Kingdom. Those looking to explore the town’s Lanna heritage should check out two significant Lanna temple sites: Wat Phra That Chae Haeng and Wat Phumin.

Phrae is home to Wat Phra That Cho Hae. The temple is still the primary spiritual center of Phrae, and is famed for its striking golden Lanna-style stupa. The town also houses a fine example of late-Lanna-style architecture: Khum Chao Luang. It was built as a royal residence in 1892 and is a fine example of Lanna teak architecture. The mansion serves as a museum in modern times.

Lanna culture you can still experience

The Kam Muang language and the Tai Tham script

Kam Muang (Northern Thai) remains the heart of northern identity, spoken daily across markets, homes, and local shops. While Central Thai is used for official matters, the local dialect retains its distinct tones and vocabulary. Its ancient written form, the Tai Tham script, was traditionally carved into palm-leaf manuscripts for Buddhist scriptures. Today, you can still see this elegant, rounded script on temple signboards and ceremonial banners across former Lanna territories.

Lanna architecture in teak and brick

Lanna building styles reflect harmony with nature, featuring tiered wooden roofs, low sweeping eaves, and carved gables called kalae. Sturdy teak structures sit alongside weathered brick stupas. You can admire this signature aesthetic across the region at landmarks like Chiang Mai’s Wat Phan Tao, Nan’s Wat Phra That Chae Haeng, Lampang’s grand Wat Phra That Lampang Luang, and the dramatic teak assembly hall at Phrae’s Wat Chong Kham.

Northern Thai food and the khantoke meal

Distinct from better-known southern curries, Northern Thai cuisine emphasizes earthy herbs, milder spices, and sticky rice eaten by hand. A traditional khantoke meal features a low, round pedestal tray laden with regional specialties like khao soi (coconut curry noodle soup), sai oua (Thai/Laotian pork sausage), and rich chili dips (nam prik). Sitting floor-level around a shared tray offers an authentic connection to traditional Lanna hospitality and community dining. 

Textiles, silverwork and Bo Sang umbrellas

Traditional crafts continue to keep Lanna culture and heritage alive across the region too. Local weavers still produce beautiful pha sin sarongs using Lanna-era techniques passed down through generations, while silversmiths along Chiang Mai’s historic Wualai Road preserve royal court metalworking by hand-hammering Buddhist motifs. While in Bo Sang – to the east of Chiang Mai – the umbrella trade reflects traditional Lanna resourcefulness, transforming local bamboo and handmade Sa mulberry paper into vibrant, waterproof works of art. 

Yi Peng and the Lanna lantern festival

Falling on the full moon of the second month of the Lanna lunar calendar, Yi Peng is a traditional Lanna festival still celebrated in Northern Thailand. It transforms northern Thailand into a luminous wonderland. Locals release thousands of glowing rice-paper lanterns (khom loi) into the night sky to let go of bad luck and pay homage to the Buddha. Temples and homes are adorned with colorful hanging paper lanterns, creating a spellbinding atmosphere that coincides with the floating water lantern festival of Loy Krathong.

Inthakhin, Songkran and the Lanna festival year

The Lanna calendar revolves around sacred communal celebrations that honour ancestral spirits and the Buddhist faith. In spring, Songkran brings water-pouring rituals to cleanse away the past year, alongside the building of sand stupas in temple grounds. Soon after, the Inthakhin City Pillar Festival invokes rains and prosperity through floral offerings. Throughout the year, seasonal temple fairs, merit-making parades, and long-boat races keep ancient northern traditions alive and vibrant.

Top Tip: “Songkran festivities continue for a week in the north, whereas on the southern islands, they typically only last one day. The festivities are seen by foreigners as being a nation-wide waterfight, but in truth they are more spiritual to the locals. Avoid travelling when the festivities are happening as you and your belongings will get wet.”
