Thailand, officially the Kingdom of Thailand, formerly known as Siam, is a country located at the centre of the Indochina peninsula in 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.
Thailand is home to several distinct geographic regions, partly corresponding to the provincial groups. The north of the country is the mountainous area of the Thai highlands, with the highest point being Doi Inthanon in the Thanon Thong Chai Range at 2,565 metres (8,415 ft) above sea level. The northeast, Isan, consists of the Khorat Plateau, bordered to the east by the Mekong River. The centre of the country is dominated by the predominantly flat Chao Phraya river valley, which runs into the Gulf of Thailand. 
Thai culture has been shaped by many influences, including Indian, Lao, Burmese, Cambodian, and Chinese.
Its traditions incorporate a great deal of influence from India, China, Cambodia, and the rest of Southeast Asia. Thailand's national religionTheravada Buddhism is important to modern Thai identity. Thai Buddhism has evolved over time to include many regional beliefs originating from Hinduism, animism as well as ancestor worship. The official calendar in Thailand is based on the Eastern version of the Buddhist Era, which is 543 years ahead of the Gregorian (western) calendar. For example, the year AD 2011 is 2554 BE in Thailand.
Several different ethnic groups, many of which are marginalized, populate Thailand. Some of these groups overlap into Burma, Laos, Cambodia, and Malaysia and have mediated change between their traditional local culture, national Thai and global cultural influences. Overseas Chinese also form a significant part of Thai society, particularly in and around Bangkok. Their successful integration into Thai society has allowed for this group to hold positions of economic and political power.
