context_page_description: The Tai ethnic group migrated into mainland Southeast Asia over a period of centuries. The word Siam may have originated from Pali or Sanskrit श्याम or Mon ရာမည, probably the same root as Shan and Ahom. Chinese: 暹羅; pinyin: Xiānluó was the name for the northern kingdom centred on Sukhothai and Sawankhalok. To the Thai, the name has mostly been Mueang Thai.
  The country's designation as Siam by Westerners likely came from the Portuguese. Portuguese chronicles noted that the Borommatrailokkanat, king of the Ayutthaya Kingdom, sent an expedition to the Malacca Sultanate at the southern tip of the Malay Peninsula in 1455. Following their conquest of Malacca in 1511, the Portuguese sent a diplomatic mission to Ayutthaya. A century later, on 15 August 1612, The Globe, an East India Company merchantman bearing a letter from King James I, arrived in "the Road of Syam". "By the end of the 19th century, Siam had become so enshrined in geographical nomenclature that it was believed that by this name and no other would it continue to be known and styled."
  Indianised kingdoms such as the Mon, the Khmer Empire and Malay states of the Malay Peninsula and Sumatra ruled the region.
context_section_description: The most recent and accurate theory about the origin of the Tai people stipulates that Guangxi in China is really the Tai motherland instead of Yunnan. A large number of Tai people known as the Zhuang still live in Guangxi today. Around 700 AD, Tai people who did not come under Chinese influence settled in what is now Điện Biên Phủ in modern Vietnam according to the Khun Borom legend. Based on layers of Chinese loanwords in proto-Southwestern Tai and other historical evidence, Pittayawat Pittayaporn (2014) proposed that this migration must have taken place sometime between the 8th–10th centuries. Tai speaking tribes migrated southwestward along the rivers and over the lower passes into Southeast Asia, perhaps prompted by the Chinese expansion and suppression. Chinese historical texts record that, in 722, 400,000 'Lao' rose in revolt behind a leader who declared himself the king of Nanyue in Guangdong. After the 722 revolt, some 60,000 were beheaded. In 726, after the suppression of a rebellion by a 'Lao' leader in the present-day Guangxi, over 30,000 rebels were captured and beheaded. In 756, another revolt attracted 200,000 followers and lasted four years. In the 860s, many local people in what is now North Vietnam sided with attackers from Nanchao, and in the aftermath, some 30,000 of them were beheaded. In the 1040s, a powerful matriarch-shamaness by the name of A Nong, her chiefly husband, and their son, Nong Zhigao, raised a revolt, took Nanning, besieged Guangzhou for fifty seven days, and slew the commanders of five Chinese armies sent against them before they were defeated, and many of their leaders were killed. As a result of these three bloody centuries, the Tai began to migrate southwestward.
  The Simhanavati legend tells us that a Tai chief named Simhanavati drove out the native Wa people and founded the city of Chiang Saen around 800 CE. For the first time, the Tai people made contact with the Indianized civilisations of Southeast Asia. Through Hariphunchai, the Tais of Chiang Saen adopted Theravada Buddhism and Sanskrit royal names. Wat Phrathat Doi Tong, constructed around 850, signified the piety of Tai people on the Theravada religion. Around 900, major wars were fought between Chiang Saen and Hariphunchai. Mon forces captured Chiang Saen and its king fled. In 937, Prince Prom the Great took Chiang Saen back from the Mon and inflicted severe defeats on Hariphunchai.
  Around 1000 CE, Chiang Saen was destroyed by an earthquake with many inhabitants killed. A council was established to govern the kingdom for a while, and then a local Wa man known as Lavachakkaraj was elected king of the new city of Chiang Saen or Ngoenyang. The Lavachakkaraj dynasty would rule over the region for about 500 years.
  Overpopulation might have encouraged the Tais to seek their fortune further southwards. By 1100 CE, the Tai had established themselves as Po Khuns (ruling fathers) at Nan, Phrae, Songkwae, Sawankhalok, and Chakangrao on the upper Chao Phraya River. These southern Tai princes faced Khmer influence from the Lavo Kingdom. Some of them became subordinates to it.
