History of Thailand

The history of Thailand begins with Bronze and Iron Age sites such as Ban Chiang, occupied by about 1500 BCE. In the first millennium the region was held by Mon, Lawa, Khmer and Malay communities. Kra-Dai-speaking Tai groups moved from South China into Mainland Southeast Asia between the 8th and 10th centuries, and in greater numbers in the 13th under pressure from the Mongol armies in China. They settled in the north and in central city-states such as Lavo, mixed with the existing population, and took up the Dvaravati culture of the Chao Phraya Basin.
