Geography and climate

Located at the center of the Indochinese Peninsula, Thailand borders Myanmar, Laos, Cambodia, and Malaysia, with coastlines on the Andaman Sea and the Gulf of Thailand. Its terrain includes northern mountains such as Doi Inthanon (2,565 m), the Khorat Plateau in the northeast, the fertile Chao Phraya River plain in the center, and southern peninsular beaches. The tropical climate features three seasons—hot (Mar–May), rainy (Jun–Oct), and cool (Nov–Feb).

History and politics

A unified Thai kingdom emerged in the 13th century. Siam became Thailand in 1939 and adopted a constitutional monarchy after the 1932 revolution. The nation has experienced alternating civilian and military governments, with numerous coups shaping its modern politics. Today it remains a parliamentary democracy under a constitutional monarchy, with a strong military influence.

Economy

Thailand has Southeast Asia’s second-largest economy, with GDP around US$500 billion (2022). Its free-market system depends heavily on exports—electronics, automobiles, and agricultural products such as rice and rubber—and on tourism, which is a major foreign-exchange earner. Despite steady growth, income inequality and environmental challenges persist.

Society and culture

About 93 % of Thais are Buddhist, and Buddhism shapes national identity and daily life. The population is ethnically diverse, including Central Thai, Isan (Lao), Malay, and Hill Tribes communities. Thai cuisine, arts, and festivals such as Songkran (Water Festival) and Loy Krathong (Festival of Lights) are central to cultural expression. The phrase “Land of Smiles” reflects the country’s reputation for hospitality.
