Chiang Rai (Thai: เชียงราย, pronounced [t͡ɕʰīa̯ŋ rāːj]; Northern Thai: ᨩ᩠ᨿᨦᩁᩣ᩠ᨿ, เจียงฮาย, Northern Thai pronunciation: [t͡ɕīa̯ŋ hāːj]) is the northernmost major city in Thailand, with a population of about 200,000 people. It is located in Mueang Chiang Rai District, Chiang Rai Province. Chiang Rai was established as a capital city in the reign of King Mangrai, in 1262 CE.
|Northern Thai name|
The city was founded by King Mangrai in 1262: 208 and became the capital of the Mangrai Dynasty. The word 'Chiang' means 'city' in Thai, so Chiang Rai would mean 'the City of (Mang) Rai'. Subsequently, Chiang Rai was conquered by Burma and remained under Burmese rule for several hundred years. It was not until 1786 that Chiang Rai became a Chiang Mai vassal. Siam (Thailand) annexed Chiang Mai in 1899, and Chiang Rai was proclaimed a province of Thailand in 1933.
In 1432, during the reign of King Sam Fang Kaen of the Mangrai Dynasty (1402–1441), the Phra Kaeo, or Emerald Buddha, the most revered Buddha statue, was discovered in Chiang Rai when an earthquake split the chedi at Wat Phra Kaeo of Chiang Rai city. The beautiful jade figure was then seen concealed within. Another telling of the story has the "Emerald Buddha" hastily covered in mud just before marauders entered to pillage. Many years later, the clunky-looking mud Buddha was found to actually house a magnificent jade statue, perhaps by way of the earthquake mentioned above—which caused a piece of the clay to break off—revealing the jade beneath.
In 1992, the city pillar was moved from Wat Klang Wiang to Wat Phra That Doi Chom Thong, where it is known as Sadue Mueang (Thai: สะดือเมือง), the "navel" or omphalos of the city.
Chiang Rai lies on the flat alluvial plain of the Kok River, a tributary of the Mekong, between the Daen Lao Range in the north and the Phi Pan Nam Range in the south. The Kok River runs along Chiang Rai's north side, flowing eastwards out of Burma at Tha Ton(ท่าตอม) town, bending north-eastwards and joining the Mekong River about 40 kilometres (25 mi) north-east of the city. The Lao River, a tributary of the Kok, flows south of Chiang Rai.
There are four bridges spanning the Kok River within the town's boundaries, each running south–north. Most of the terrain surrounding Chiang Rai town is either flat or has moderate hills. The exception is outward in the west and north-west directions, where limestone hills are evident, some of which have vertical exposed cliffs. That is also the direction where most of the region's hill tribe people have their villages, further afield.
The city is 860 kilometres (530 mi) north of Bangkok, about 200 kilometres (120 mi) north-east of Chiang Mai, 62 kilometres (39 mi) south of Mae Sai and the Burmese border; 60 kilometres (37 mi) south-west of the town of Chiang Saen on the Mekong River across from Laos; and 90 kilometres (56 mi) north of Phayao town. The Golden Triangle, the tripoint of the Thailand, Laos and Myanmar borders, is 55 kilometres (34 mi) north-east of the city.
Chiang Rai has a tropical wet and dry climate (Köppen climate classification Aw). Winters are fairly dry and warm. Temperatures rise until April, which is hot with the average daily maximum at 34.5 °C (94.1 °F). The monsoon season runs from late April through October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm.
