Southeast Asia has been inhabited for more than half a million years. Recent archaeological studies suggest that by 4000 BC, communities in what is now Thailand had emerged as centers of early bronze metallurgy. This development, along with the cultivation of wet rice, provided the impetus for social and political organization. Research suggests that these innovations may actually have been
transmitted from there to the rest of Asia, including to China.
The Thai are related linguistically to Tai groups originating in southern China. Migrations from southern China to Southeast Asia may have occurred in the 6th and 7th centuries. Malay, Mon, and Khmer civilizations flourished in the region prior to the arrival of the ethnic Tai.
Thais date the founding of their nation to the 13th century. According to tradition, in 1238, Thai chieftains overthrew their Khmer overlords at Sukhothai and established a Thai kingdom. After its decline, a new Thai kingdom emerged in 1350 on the Chao Praya River. At the same time, there was an equally important Tai kingdom of Lanna, centered in Chiang Mai, which rivaled Sukothai and
Ayutthaya for centuries, and which defines northern Thai identity to this day.
The first ruler of the Kingdom of Ayutthaya, King Rama Thibodi, made two important contributions to Thai history: the establishment and promotion of Theravada Buddhism as the official religion--to differentiate his kingdom from the neighboring Hindu kingdom of Angkor--and the compilation of the Dharmashastra, a legal code based on Hindu sources and traditional Thai custom. The Dharmashastra
remained a tool of Thai law until late in the 19th century. Beginning with the Portuguese in the 16th century, Ayutthaya had some contact with the West, but until the 1800s, its relations with neighboring kingdoms and principalities, as well as with China, were of primary importance.
After more than 400 years of power, in 1767, the Kingdom of Ayutthaya was brought down by invading Burmese armies and its capital burned. After a single-reign capital established at Thonburi by Taksin, a new capital city was founded in 1782, across the Chao Phraya at the site of present-day Bangkok, by the founder of the Chakri dynasty. The first Chakri king was crowned Rama I. Rama's heirs
became increasingly concerned with the threat of European colonialism after British victories in neighboring Burma in 1826.
The first Thai recognition of Western power in the region was the Treaty of Amity and Commerce with the United Kingdom in 1826. In 1833, the United States began diplomatic exchanges with Siam, as Thailand was called until 1938. However, it was during the later reigns of Rama IV (or King Mongkut, 1851-68), and his son Rama V (King Chulalongkorn (1868-1910), that Thailand established firm
rapprochement with Western powers. The Thais believe that the diplomatic skills of these monarchs, combined with the modernizing reforms of the Thai Government, made Siam the only country in South and Southeast Asia to avoid European colonization.
In 1932, a bloodless coup transformed the Government of Thailand from an absolute to a constitutional monarchy. King Prajadhipok (Rama VII) initially accepted this change but later surrendered the kingship to his 10-year-old nephew. Upon his abdication, King Prajadhipok said that the obligation of a ruler was to reign for the good of the whole people, not for a select few. Although nominally a
constitutional monarchy, Thailand was ruled by a series of military governments interspersed with brief periods of democracy from that time until the 1992 elections. Since the 1992 elections, Thailand has been a functioning democracy with constitutional changes of government.
As with the rest of Southeast Asia, Thailand was occupied by the Japanese during the Second World War. Since Japan's defeat in 1945, Thailand has had very close relations with the United States. Threatened by communist revolutions in neighboring countries such as Vietnam, Cambodia, and Laos, Thailand actively sought to contain communist expansion in the region. Recently, Thailand also has been
an active member in multilateral organizations like the Association of South East Asian Nations (ASEAN) and the Asia-Pacific Economic Cooperation (APEC) forum.
Beginning with a brief experiment in democracy during the mid-1970s, civilian democratic political institutions slowly gained greater authority, culminating in 1988 when Chatichai Choonavan--leader of the Thai Nation Party--assumed office as the country's first democratically elected prime minister in more than a decade. Three years later, yet another bloodless coup ended his term.
Shortly afterward, the military appointed Anand Panyarachun, a businessman and former diplomat, to head a largely civilian interim government and promised to hold elections in the near future. However, following inconclusive elections, former army commander Suchinda Kraprayoon was appointed prime minister. Thais reacted to the appointment by demanding an end to military influence in
government. Demonstrations were violently suppressed by the military; in May 1992, soldiers killed at least 50 protesters.
Domestic and international reaction to the violence forced Suchinda to resign, and the nation once again turned to Anand Panyarachun, who was named interim prime minister until new elections in September 1992. In those elections, the political parties that had opposed the military in May 1992 won by a narrow majority, and Chuan Leekpai, a leader of the Democratic Party, became Prime Minister.
Chuan dissolved Parliament in May 1995, and the Thai Nation Party won the largest number of parliamentary seats in subsequent elections. Party leader Banharn Silpa-archa became Prime Minister but held the office only little more than a year. Following elections held in November 1996, Chavalit Youngchaiyudh formed a coalition government and became Prime Minister. The onset of the Asian financial
crisis caused a loss of confidence in the Chavalit government and forced him to hand over power to Chuan Leekpai in November 1997. Chuan formed a coalition government based on the themes of prudent economic management and institution of political reforms mandated by Thailand's 1997 constitution.
In the January 2001 elections, telecommunications multimillionaire Thaksin Shinawatra and his Thai Rak Thai (TRT) party won an overwhelming victory on a populist platform of economic growth and development. TRT enjoys an absolute majority in the lower house of the Parliament, controlling 365 of 500 seats. In a cabinet reshuffle of October 2002, the Thaksin administration further put its stamp
on the government. A package of bureaucratic reform legislation created six new ministries in an effort to streamline the bureaucratic process and increase efficiency and accountability.
