Thailand occupies the western half of the Indochinese peninsula and the northern two-thirds of the Malay Peninsula in southeast Asia. Its neighbors are Burma (Myanmar) on the north and west, Laos on the north and northeast, Cambodia on the east, and Malaysia on the south. Thailand is about the size of France.
The Thais first began settling their present homeland in the 6th century, and by the end of the 13th century ruled most of the western portion. During the next 400 years, they fought sporadically with the Cambodians to the east and the Burmese to the west. Formerly called Siam, Thailand has never experienced foreign colonization. The British gained a colonial foothold in the region in 1824, but by 1896 an Anglo-French accord guaranteed the independence of Thailand. A coup in 1932 demoted the monarchy to titular status and established representative government with universal suffrage.
At the outbreak of World War II, Japanese forces attacked Thailand. After five hours of token resistance Thailand yielded to Japan on Dec. 8, 1941, subsequently becoming a staging area for the Japanese campaign against Malaya. Following the demise of a pro-Japanese puppet government in July 1944, Thailand repudiated the declaration of war it had been forced to make in 1942 against Britain and the U.S.
By the late 1960s the nation's problems largely stemmed from conflicts brewing in neighboring Cambodia and Vietnam. Although Thailand had received $2 billion in U.S. economic and military aid since 1950 and had sent troops (paid by the U.S.) to Vietnam while permitting U.S. bomber bases on its territory, the collapse of South Vietnam and Cambodia in spring 1975 brought rapid changes in the country's diplomatic posture. At the Thai government's insistence, the U.S. agreed to withdraw all 23,000 U.S. military personnel remaining in Thailand by March 1976.
