Mainstream Thai historians count Sukhothai as the first kingdom of Thai people.
According to George Cœdès, the word Thai (ไทย) means 'free man' in the Thai language, "differentiating the Thai from the natives encompassed in Thai society as serfs".
The Chinese called this region Xian, which the Portuguese converted into Siam." The signature of King Mongkut (r.
1851–1868) reads SPPM (Somdet Phra Poramenthra Maha) Mongkut Rex Siamensium (Mongkut King of the Siamese), giving the name Siam official status until 24 June 1939 when it was changed to "Thailand".
Thailand is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the southern extremity of Myanmar.
Its maritime boundaries include Vietnam in the Gulf of Thailand to the southeast, and Indonesia and India on the Andaman Sea to the southwest. Although nominally the country is a constitutional monarchy and parliamentary democracy, the most recent coup, in 2014, established a de facto military dictatorship under a junta.
