Southeast Asia is one of the world's most popular tourist destinations, and for a reason. Some of the countries here have it all: a tropical climate, warm (or hot!) all year around, rich culture, gorgeous beaches, wonderful food and last but not least, low prices.

Southeast Asian history is very diverse, and has to an important extent been shaped by European colonialism. The very term Southeast Asia was invented by American Naval strategists around 1940. Southeast Asia was prior to WWII referred to with reference to the colonial powers; farther India for Burma and Thailand, with reference to the main British colony of India, although Thailand was never formally colonized; Indochina referred to the French colonies of Cambodia, Vietnam and Laos and Indonesia and parts of maritime Southeast Asia was referred to as the Dutch East Indies.

Southeast Asia's major languages are not mutually intelligible. English is a traveller's most useful language overall, although for longer stays in any Southeast Asian country picking up at least some of the local language is essential.
