Thai people, who originally lived i

Thai people, who originally lived in southwestern China, migrated into mainland Southeast Asia over a period of many centuries. The oldest known mention of their existence in the region by the exonym Siamese is in a 12th-century inscription at the Khmer temple complex of Angkor Wat in Cambodia, which refers to syam, or "dark brown", people.[1] It was believed that Siam derived from Sanskrit śyāma or "brown (people)" with a contemptuous signification. Chinese: 暹罗; pinyin: XiānLuó was the name for the northern kingdom centred on Sukhothai and Sawankhalok, but to the Thai themselves, the name of the country has always been Mueang Thai.[2]
