Thailand (d/ TY-land), officially the Kingdom of Thailand and formerly known as Siam, is a unitary state at the center of the Southeast Asian Indochinese peninsula composed of 76 provinces. At 513,120 km2 and over 68 million people, Thailand is the world's 50th largest country by total area and the 21st-most-populous country. The capital and largest city is Bangkok, a special administrative area. 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. Even though constitutional monarchy and parliamentary democracy form of government was established in 1932, the most recent coup d'état in 2014 made Thailand currently a de facto military dictatorship.

Tai peoples migrated from southwestern China to mainland Southeast Asia since the 11th century. The oldest known mention of their presence in the region by the exonym Siamese is in a 12th-century inscription at the Angkor Wat. Various Indianised kingdoms such as the Mon, the Khmer Empire and Malay states ruled the region, competing with Thai states such as Ngoenyang, the Sukhothai Kingdom, Lan Na and the Ayutthaya Kingdom, which rivalled each other. Before the end of the 15th century, Ayutthaya Kingdom was the new great power in the region. Europeans contact began with a Portuguese diplomatic mission to Ayutthaya in 1511. During cosmopolitan Narai's reign (1656–88), Ayutthaya was very prosperous and Europeans recognized it as one of the greatest kingdoms in the region. However, Ayutthaya then gradually declined and was ultimately destroyed in 1767. Taksin quickly unified the fragmented territory and crowned king of short-lived Thonburi Kingdom. In his final years, he and his sons was executed by his companion Buddha Yodfa Chulaloke, the first monarch of reigning Chakri dynasty and founder of Rattanakosin Kingdom in 1782.

The ensuing centuries saw colonial powers pressure on Siam, but remained the only South East Asian country not colonized by the West. The country was modernized and centralized during Chulalongkorn's reign (1868–1910). Siam joined the Allies in World War I. Bloodless Siamese revolution of 1932 changed the kingdom into constitutional monarchy. In the 1930s, the military dominated the politics and the country turned into a fascism. Thailand allied with Japan during Thailand in World War II but most Allied powers did not accept Thai declaration of war. Thailand allied with the United States and led anti-communist role in the region. Sarit's coup and premiership revived the monarchy's role in politics. Popular uprising in 1973 was a result of internal conflict Thailand and leads to a brief period of parliamentary democracy which ended in 1976. Thailand is still considered a "partial democracy" for many decades. Since the 2000s seen the country pitted in a political crisis between supporters and opponents of ex-Prime Minister Thaksin Shinawatra, with two coups, most recently in 2014. Its current and 20th constitution was ratified on April 6, 2017, during military junta's watch.

Thailand is a founding member of ASEAN and a long-time allied of the United States. Thailand is considered a regional power in Southeast Asia and a middle power in global affairs.[14] With a high level of human development, Thailand is classified as a newly industrialized economy which was heavily dependent on exports. Manufacturing, agriculture, and tourism are leading sectors of the economy.[15][16] Its economy is the second-largest in Southeast Asia and the 20th largest by PPP.


Thailand (d/ TY-land or d/ TY-lənd;[17] Thai: ประเทศไทย, RTGSPrathet Thai, pronounced [pratʰêːt tʰaj] (About this sound listen)), officially the Kingdom of Thailand (Thai: ราชอาณาจักรไทย, RTGSRatcha-anachak Thai  [râːtt͡ɕʰaʔaːnaːt͡ɕàk tʰaj] (About this sound listen), Chinese: 泰国), formerly known as Siam (Thai: สยาม, RTGSSayam  [sajǎːm]), is a country at the centre of the Indochinese peninsula in Southeast Asia.

Etymology of "Siam"

The country has always been called Mueang Thai by its citizens. By outsiders prior to 1949, it was usually known by the exonym Siam (Thai: สยาม RTGSSayam, pronounced [sajǎːm], also spelled Siem, Syâm, or Syâma).[citation needed] The word Siam has been identified[by whom?] with the Sanskrit Śyāma (श्याम, meaning "dark" or "brown"). The names Shan and A-hom seem to be variants of the same word. The word Śyâma is possibly not its origin, but a learned and artificial distortion.[clarification needed][18] Another theory is the name derives from Chinese: "Ayutthaya emerged as a dominant centre in the late fourteenth century. The Chinese called this region Xian, which the Portuguese converted into Siam." (Baker and Phongpaichit, A History of Thailand, 8) A further possibility is that Mon-speaking peoples migrating south called themselves 'syem' as do the autochthonous Mon-Khmer-speaking inhabitants of the Malay Peninsula.[citation needed]

SPPM Mongkut Rex Siamensium, King Mongkut's signature

The signature of King Mongkut (r. 1851–1868) reads SPPM (Somdet Phra Poramenthra Maha) Mongkut King of the Siamese, giving the name "Siam" official status until 24 June 1939 when it was changed to Thailand.[19] Thailand was renamed to Siam from 1946 to 1948, after which it again reverted to Thailand.

Etymology of "Thailand"

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."[20] A famous Thai scholar argued that Thai (ไท) simply means "people" or "human being", since his investigation shows that in some rural areas the word "Thai" was used instead of the usual Thai word "khon" (คน) for people.[21] According to Michel Ferlus, the ethnonyms Thai/Tai (or Thay/Tay) would have evolved from the etymon *k(ə)ri: 'human being' through the following chain: *kəri: > *kəli: > *kədi:/*kədaj > *di:/*daj > *dajA (Proto-Southwestern Tai) > tʰajA2 (in Siamese and Lao) or > tajA2 (in the other Southwestern and Central Tai languages classified by Li Fangkuei).[22] Michel Ferlus' work is based on some simple rules of phonetic change observable in the Sinosphere and studied for the most part by William H. Baxter (1992).[23]

While Thai people will often refer to their country using the polite form prathet Thai (Thai: ประเทศไทย), they most commonly use the more colloquial term mueang Thai (Thai: เมืองไทย) or simply Thai, the word mueang, archaically a city-state, commonly used to refer to a city or town as the centre of a region. Ratcha Anachak Thai (Thai: ราชอาณาจักรไทย) means "kingdom of Thailand" or "kingdom of Thai". Etymologically, its components are: ratcha (Sanskrit राजन्, rājan, "king, royal, realm") ; -ana- (Pali āṇā "authority, command, power", itself from the Sanskrit आज्ञा, ājñā, of the same meaning) -chak (from Sanskrit चक्र cakra- "wheel", a symbol of power and rule). The Thai National Anthem (Thai: เพลงชาติ), written by Luang Saranupraphan during the extremely patriotic 1930s, refers to the Thai nation as: prathet Thai (Thai: ประเทศไทย). The first line of the national anthem is: prathet thai ruam lueat nuea chat chuea thai (Thai: ประเทศไทยรวมเลือดเนื้อชาติเชื้อไทย), "Thailand is the unity of Thai flesh and blood."
