Thailand means “land of the free.” And throughout its 800-year history, it can boast the distinction of being the only country in Southeast Asia never to have been colonized. The Thais founded their kingdom in the southern part of China, which is Yunnan, Kwangsi and Canton today. A great number of people migrated south as far as the Chao Phraya Basin and settled down over the Central Plain under the sovereignty of the Khmer Empire, whose culture they probably accepted.
The Thais began to emerge as a dominant force in the region in the13th century, gradually asserting independence from existing Khmer and Mon kingdoms. Called by its rulers “the dawn of happiness”, this is often considered the golden era of Thai history, an ideal Thai state in a land of plenty governed by paternal and benevolent kings.
