Thailand, officially the Kingdom of Thailand and formerly known as Siam, is a country located at the center of Southeast Asia. It is bordered to the north by Burma 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 Burma. Its maritime boundaries include Vietnam in the Gulf of Thailand to the southeast and Indonesia and India in the Andaman Sea to the southwest.
The country is a kingdom, with most recorded reigns in the world; a constitutional monarchy with King Rama IX, the ninth king of the House of Chakri, who has reigned since 1946, making him the world's longest-serving current head of state and the longest-reigning monarch in Thai history. The king is officially titled Head of State, the Head of the Armed Forces, an Upholder of the Buddhist religion, and the Defender of all Faiths.
Thailand is the world's 50th largest country in terms of total area (slightly smaller than Yemen and slightly larger than Spain), with a surface area of approximately 513,000 km2 (198,000 sq mi), and the 21st most-populous country, with approximately 64 million people. The largest city is Bangkok, the capital, which is also the country's center of political, commercial, industrial and cultural activities. About 75% of the population is ethnically Thai, 14% is of Chinese origin, and 3% is ethnically Malay; the rest belong to minority groups including Mons, Khmers and various hill tribes. The country's official language is Thai. The primary religion is Buddhism, which is practiced by around 95% of all Thais.
Thailand experienced rapid economic growth between 1985 and 1995 and is a newly industrialized country with tourism, due to well-known tourist destinations such as Ayutthaya, Pattaya, Bangkok, Phuket, Krabi, Chiang Mai, and Ko Samui, and exports contributing significantly to the economy. There are approximately 2.2 million legal and illegal migrants in Thailand. Thailand has also attracted a number of expatriates from developed countries.
The politics of Thailand are currently conducted within the framework of a constitutional monarchy, whereby the Prime Minister is the head of government and a hereditary monarch is head of state. The judiciary is independent of the executive and the legislative branches. Thai kingdoms and late Kingdom of Siam were under absolute rule of the kings. However, after the 'democratic revolution' in 1932, led by westernized bureaucrats and traditional-oriented military, the country officially became under a constitutional monarchy with a prime minister as the head of government. The first written constitution was issued. Yet the politics became the arena of fighting factions among old and new elites, bureaucrats, and generals. Coups happened from time to time, often bringing the country under the rule of yet another junta.
The official language of Thailand is Thai, a Kradai language closely related to Lao, Shan in Burma, and numerous smaller languages spoken in an arc from Hainan and Yunnan south to the Chinese border. It is the principal language of education and government and spoken throughout the country. The standard is based on the dialect of the central Thai people, and it is written in the Thai alphabet, an abugida script that evolved from the Khmer script. Several other dialects exist, and coincide with the regional designations. Southern Thai is spoken in the southern provinces, and Northern Thai is spoken in the provinces that were formally part of the independent kingdom of Lannathai.
Thai cuisine is the national cuisine of Thailand. Thai cuisine places emphasis on lightly prepared dishes with strong aromatic components. Thai cuisine is known for being spicy. Balance, detail and variety are important to Thai cooking. Thai food is known for its balance of the four fundamental taste senses in each dish or the overall meal: sour, sweet, salty, and (optional) bitter.
