History of Thailand

The 13th-century kingdom of Sukhothai saw the birth of Thai script. It was followed by the kingdom of Ayutthaya (1351-1767), destroyed by the Burmese. The Chakri dynasty, founded in 1782, made Bangkok its capital and still reigns. Siam, renamed Thailand in 1939, is the only country in South-East Asia never to have been colonised. Absolute monarchy ended in 1932; since then the country has seen many coups, the latest in 2014. King Bhumibol reigned for 70 years, from 1946 to 2016.

Geography of Thailand

The central plain, watered by the Chao Phraya, is the country’s rice bowl. The north is mountainous, the north-east covered by the Khorat plateau, and the south by a long peninsula bordering the Gulf of Thailand and the Andaman Sea.
