Thailand
Thailand is a constitutional monarchy with King Bhumibol Adulyadej, the ninth king of the House of Chakri, as the ruling monarch. The King has reigned for more than half a century, making him the longest reigning Thai monarch and the longest reigning current monarch in the world. The King is recognized as the Head of State, the Head of the Armed Forces, the Upholder of the Buddhist religion, and Defender of the Faith. Thailand is the only country in Southeast Asia that has never been ruled by a European power. However, during the Second World War, and while claiming neutrality, Thailand was occupied by the armed forces of the Empire of Japan who built the infamous 'Death Railway' using captured Allied Prisoners of War and slave Asian labourers.
The country's official name was Siam (Thai: สยาม; IPA: [saˈjaːm], RTGS: Sayam) until June 23, 1939, when it was changed to Thailand. It was renamed Siam from 1945 to May 11, 1949, after which it was again renamed Thailand. Also spelled Siem, Syâm or Syâma, it has been identified with the Sanskrit Śyâma, dark or brown. But the names Shan and A-hom seem to be variants of the same word, and Śyâma is possibly not its origin but a learned and artificial distortion.
The word Thai (ไทย) is not, as commonly believed, derived from the word Tai (ไท) meaning "free" in the Thai language; it is, however, the name of an ethnic group from the central plains (the Thai people). A famous Thai scholar argued that Tai (ไท) simply means "people" or "human being" since his investigation shows that in some rural areas the word "Tai" was used instead of the usual Thai word "khon" (คน) for people. The phrase "Land of the free" is derived from the fact that the Thai are proud of the fact that Thailand is the only country in Southeast Asia never colonized by Europe.
Ratcha Anachak Thai (Thai: ราชอาณาจักรไทย) means "Kingdom of Thailand" or "Kingdom of Thai." Etymologically, its components are: -Ratcha- (from Sanskrit raja, meaning "king, royal, realm,") ; -ana- (from Pāli āṇā, "authority, command, power," itself from Sanskrit ājñā, same meaning) -chak (from Sanskrit cakra or cakraṃ meaning "wheel", a symbol of power and rule




The region known as Thailand has been inhabited by humans since the paleolithic period, about 10,000 years ago. Prior to the fall of the Khmer Empire in the 13th century, various states thrived there, such as the various Tai, Mon, Khmer and Malay kingdoms, as seen through the numerous archaeological sites and artifacts that are scattered throughout the Siamese landscape. Prior to the 12th century however, the first Thai or Siamese state is traditionally considered to be the Buddhist kingdom of Sukhothai, which was founded in 1238.
Following the decline and fall of the Khmer empire in the 13th - 14th century, the Buddhist Tai Kingdoms of Sukhothai, Lanna and Lan Chang were on the ascension. However, a century later, Sukhothai's power was overshadowed by the new kingdom of Ayutthaya, established in the mid-14th century.
After the fall of the Ayutthaya in 1767 to the Burmese, King Taksin the Great moved the capital of Thailand to Thonburi for a brief period. The current Rattanakosin era of Thai history began in 1782, following the establishment of Bangkok as capital of the Chakri dynasty under King Rama I the Great.
Thailand retains a tradition of trade with its neighboring states, and the cultures of the Indian ocean and the South China sea. European trade and influence arrived to Thailand in the 16th century, beginning with the Portuguese. Despite European pressure, Thailand is the only Southeast Asian nation never to have been colonised. Two main reasons for this were that Thailand had a long succession of very able rulers in the 1800s and that it was able to exploit the rivalry and tension between the French and the British. As a result, the country remained as a buffer state between parts of Southeast Asia that were colonized by the two colonial powers. Despite this, Western influence led to many reforms in the 19th century and major concessions, most notably being the loss of large territory on the east side of the Mekong to the French and the step by step absorption by Britain of the Shan (Thai Yai) States (now in Burma) and the Malay Peninsula. The loss initially included Penang and Tumasik and eventually culminated in the loss of three predominantly ethnic-Malay southern provinces, which later became Malaysia's three northern states, under the Anglo-Siamese Treaty of 1909.
In 1932, a bloodless revolution resulted in a new constitutional monarchy. During World War II, Thailand became an ally of Japan while at the same time maintaining an active anti-Japanese resistance movement known as the Seri Thai. After the war, Thailand emerged as an ally of the United States. As with many of the developing nations during the Cold War, Thailand then went through decades of political transgression characterised by coups d'état as one military regime replaced another, but eventually progressed towards a stable prosperity and democracy in the 1980s.
In 1997, Thailand was hit with the Asian financial crisis and the Thai baht for a short time peaked at 56 baht to the US dollar compared to about 25 baht to the dollar before 1997. Since then, the baht has regained most of its strength and as of 26 December 2008, is valued at 34.71 baht to the US dollar.
The official calendar in Thailand is based on Eastern version of the Buddhist Era, which is 543 years ahead of the Gregorian (western) calendar. For example, the year AD 2008 is called 2551 BE in Thailand.
Since the political reform of the absolute monarchy in 1932, Thailand has had 17 constitutions and charters.Throughout this time, the form of government has ranged from military dictatorship to electoral democracy, but all governments have acknowledged a hereditary monarch as the head of state.
The 1997 Constitution was the first constitution to be drafted by popularly-elected Constitutional Drafting Assembly, and was popularly called the "People's Constitution.
The 1997 Constitution created a bicameral legislature consisting of a 500-seat House of Representatives (สภาผู้แทนราษฎร, sapha phutan ratsadon) and a 200-seat Senate (วุฒิสภา, wuthisapha). For the first time in Thai history, both houses were directly elected. Many human rights are explicitly acknowledged, and measures were established to increase the stability of elected governments. The House was elected by the first-past-the-post system, where only one candidate with a simple majority could be elected in one constituency. The Senate was elected based on the province system, where one province can return more than one Senator depending on its population size. Members of the House of Representatives served four-year terms, while Senators served six-year terms.
The court system (ศาล, saan) included a constitutional court with jurisdiction over the constitutionality of parliamentary acts, royal decrees, and political matters.
The January 2001 general election, the first election under the 1997 Constitution, was called the most open, corruption-free election in Thai history.[12] The subsequent government was the first in Thai history to complete a 4-year term. The 2005 election had the highest voter turnout in Thai history and was noted for a marked reduction in vote-buying compared to previous elections.
In early 2006, significant pressure from corruption allegations led Thaksin Shinawatra to call for a snap election. The opposition boycotted the elections and Thaksin was re-elected. Pressure continued to build, leading to a military coup on 19 September 2006
