Thailand has a wide variety of fauna and flora and boasts wide ethnic diversity as well. Thanks to its abundant resources and fertile land, it has attracted peoples of many lands, who have settled and thrived here.
The origin of the Thais is not agreed on among academics. Three decades ago it could be said with presumed certainty that the Thais originated in northwestern Szechuan in China about 4,500 years ago and later migrated south to their present homeland. However, this theory has been altered by the discovery of remarkable prehistoric artifacts in the village of Ban Chiang in the Nong Han District of Udon Thani Province in the Northeast of Thailand. These include evidence of bronze metallurgy dating back 3,500 years, as well as other indications of a culture far more sophisticated than previously believed by archaeologists. It now appears that Thais might have originated here in Thailand and later scattered to various parts of Asia, including some parts of China.
"Siam" is the name by which the country was known to the world until 1939 and again between 1945 and 1949. On May 11, 1949, an official proclamation declared that the country would henceforth be known as "Thailand." The word "Thai" means "Free," and therefore "Thailand" means "Land of the Free."
