Tai peoples in the context of "Ngoenyang"

The Assamese people are a socio-ethnic linguistic identity that has been described at various times as nationalistic or micro-nationalistic. This group is often associated with the Assamese language, the easternmost Indo-Aryan language, and Assamese people mostly live in the Brahmaputra Valley region of Assam, where they are native and constitute around 56% of the valley's population. The use of the term precedes the name of the language or the people. It has also been used retrospectively to the people of Assam before the term "Assamese" came into use. They are an ethnically diverse group formed after centuries of assimilation of Austroasiatic, Tibeto-Burman, Indo-Aryan and Tai populations, and constitute a tribal-caste continuum—though not all Assamese people are Hindus and ethnic Assamese Muslims numbering around 42 lakh (4,200,000) constitute a significant part of this identity. The total population of Assamese speakers in Assam is nearly 15.09 million which makes up 48.38% of the population of state according to the Language census of 2011.

Mass migration of Tai peoples from China (Guangxi) to Mainland Southeast Asia and Northern Thailand occurred between the 8th-10th century. The Mainland region was ruled by the Khmer Empire since 800 CE. The Thai established their own kingdoms: the semi-legendary Singhanavati Kingdom (691 BCE–638 CE) evolved into the Ngoenyang Kingdom (638–1292). In 1220, the Khmer controlled Sukhothai was conquered by the Thais and made the capital of the Sukhothai Kingdom. By 1220, the long declining Khmer Empire was mostly overrun by Thais. By the 13th century, the Sukhothai Kingdom (1238–1438) had replaced the Mon kingdoms in Central Thailand. During the reign of King Ramkhamhaeng the Thai script was created in 1283, the arts flourished, Thai institutions were developed, and people called themselves "Thai" as freed people from foreign rule.

In 1351, the Suphannabhum city-state (modern-day Suphan Buri), and Lavo city-state (modern-day Lop Buri) merged into the Ayutthaya Kingdom which was founded near the Chao Phraya River. Duarte Fernandes was the first European to arrive in Ayutthaya in 1511. Siam became the popular international name for Thailand.

Thai people, historically known as Siamese people, are an ethnic group native to Thailand. In a narrower and ethnic sense, the Thais are also a Tai ethnic group dominant in Central and Southern Thailand (Siam proper). Part of the larger Tai ethno-linguistic group native to Southeast Asia as well as Southern China, Thais speak the Sukhothai languages (Central Thai and Southern Thai language), which is classified as part of the Kra–Dai family of languages. The majority of Thais are followers of Theravada Buddhism.

Government policies during the late 1930s and early 1940s resulted in the successful forced assimilation of various ethno-linguistic groups into the country's dominant Central Thai language and culture, leading to the term Thai people to come to refer to the population of Thailand overall. This includes other subgroups of the Tai ethno-linguistic group, such as the Northern Thais and the Isan people, as well as non-Southeast Asian and non-Tai groups, the largest of which is that of the Han Chinese, who form a substantial minority ethnic group in Thailand.

Suphan Buri (Thai: สุพรรณบุรี, pronounced [sù.pʰān būrīː]), located in the central region of Thailand, is one of the country's 76 provinces (จังหวัด, changwat), its first-level administrative divisions. Suphan Buri's neighbouring provinces are (from north clockwise) Uthai Thani, Chai Nat, Sing Buri, Ang Thong, Phra Nakhon Si Ayutthaya, Nakhon Pathom and Kanchanaburi. In 2018, the province had a population of around 848,700, making up about 1.28% of the Thailand's total.

Suphan Buri Province has a moderately diverse ethnic population, the majority of which are of Tai, Mon, Lao, Chinese, and Khmer descent.

The first Mongol invasions of Burma (Burmese: မွန်ဂို–မြန်မာ စစ် (၁၂၇၇–၁၂၈၇); Chinese: 元緬戰爭) were a series of military conflicts between Kublai Khan's Yuan dynasty, a division of the Mongol Empire, and the Pagan Empire that took place between 1277 and 1287. The invasions toppled the 250-year-old Pagan Empire, and the Mongol army seized Pagan territories in present-day Dehong, Yunnan and northern Burma to Tagaung. The invasions ushered in 250 years of political fragmentation in Burma and the rise of ethnic Tai-Shan states throughout mainland Southeast Asia.

The Mongols first demanded tribute from Pagan in 1271–1272, as part of their drive to encircle the Song dynasty of China. When King Narathihapate refused, Emperor Kublai Khan himself sent another mission in 1273, again demanding tribute. It too was rejected. In 1275, the emperor ordered the Yunnan government to secure the borderlands in order to block an escape path for the Song, and permitted a limited border war if Pagan contested. Pagan did contest but its army was driven back at the frontier by the Mongol army in 1277–1278. After a brief lull, Kublai Khan in 1281 again turned his attention to Southeast Asia, demanding tribute from Pagan, the Khmer Empire, Đại Việt and Champa. When the Burmese king again refused, the emperor ordered an invasion of northern Burma. Two dry season campaigns (1283–1285) later, the Mongols had occupied down to Tagaung and Hanlin, forcing the Burmese king to flee to Lower Burma. The Mongols organized northern Burma as the province of Zhengmian.

The Kingdom of Asam now known as Ahom kingdom (/ˈɑːhɔːm/; 1228–1826) was a late medieval kingdom in the Brahmaputra Valley (present-day Assam) that retained its independence for nearly 600 years despite encountering Mughal expansion in Northeast India. Established by Sukaphaa, a Tai prince from Möng Mao (present-day Dehong Dai and Jingpo Autonomous Prefecture, China), it began as a möng in the upper reaches of the Brahmaputra based on wet rice agriculture. It expanded suddenly under Suhungmung in the 16th century and became multi-ethnic in character, casting a profound effect on the political and social life of the entire Brahmaputra valley. The kingdom became weaker with the rise of the Moamoria rebellion, and subsequently fell to repeated Burmese invasions of Assam. With the defeat of the Burmese after the First Anglo-Burmese War and the Treaty of Yandabo in 1826, control of the kingdom passed into East India Company hands.

Though it came to be called the Ahom kingdom in the colonial and subsequent times, it was largely multi-ethnic, with the ethnic Tai-Ahom people constituting less than 10% of the population toward the end.People from different ethnic groups became a part of the Ahom population due to the process known as Ahomisation. The identity of the Ahom people in this kingdom was fluid, with the king controlling who belonged to it and who did not. The Ahoms initially called their kingdom Mong Dun Shun Kham till 1401 (Assamese: xunor-xophura; English: casket of gold), but adopted Assam in later times. The British-controlled province after 1838 and later the Indian state of Assam came to be known by this name. The kingdom maintained close political ties with other Tai-states especially with Mong Kwang (Nara) till the end of its rule in the 19th century.

The Shan people (Shan: တႆး, pronounced [taj˥], or Burmese: ရှမ်းလူမျိုး, pronounced [ʃáɰ̃ lùmjó]), also known as the Tai Long (တႆးလူင်, [taj˥.loŋ˨˦]) or Tai Yai, are a Tai ethnic group of Southeast Asia. The Shan are the biggest minority of Burma (Myanmar) and primarily live in the Shan State, but also inhabit parts of Mandalay Region, Kachin State, Kayah State, Sagaing Region and Kayin State, and in adjacent regions of China (Dai people), Laos, Assam and Meghalaya (Ahom people), Cambodia (Kula people), Vietnam and Thailand. Though no reliable census has been taken in Burma since 1935, the Shan are estimated to number 4–6 million, with CIA Factbook giving an estimate of five million spread throughout Myanmar which is about 10% of the overall Burmese population.

'Shan' is a generic term for all Tai-speaking peoples within Myanmar (Burma). The capital of Shan State is Taunggyi, the fifth-largest city in Myanmar with about 390,000 people. Other major cities include Thibaw (Hsipaw), Lashio, Kengtung and Tachileik.

The Dai people (Burmese: ရှမ်းလူမျိုး; Tai Lü: ᨴᩱ/ᨴᩱ᩠ᨿ; Lao: ໄຕ; Thai: ไท; Shan: တႆး, [tai˥˩]; Tai Nüa: ᥖᥭᥰ, [tai˥]; Chinese: 傣族; pinyin: Dǎizú) are several Tai-speaking ethnic groups living in the Xishuangbanna Dai Autonomous Prefecture and the Dehong Dai and Jingpo Autonomous Prefecture of China's Yunnan Province. The Dai people form one of the 56 ethnic groups officially recognized by the People's Republic of China. By extension, the term can apply to groups in Laos, Vietnam, Thailand and Myanmar when Dai is used to mean specifically Tai Yai, Lue, Chinese Shan, Tai Dam, Tai Khao or even Tai in general. For other names, see the table below.

Thailand is a country of some 70 ethnic groups, including at least 24 groups of ethnolinguistically Tai peoples, mainly the Central, Southern, Northeastern, and Northern Thais; 22 groups of Austroasiatic peoples, with substantial populations of Northern Khmer and Kuy; 11 groups speaking Sino-Tibetan languages ('hill tribes'), with the largest in population being the Karen; 3 groups of Austronesian peoples, i.e., the Malay, the majority ethnic group in the southernmost three provinces, together with the Moken and Urak Lawoi ('sea gypsies'); and both groups of Hmong-Mien. Other ethnic groups include longstanding immigrant communities such as the Chinese, Indians, Persian, and Portuguese.
