Cambodia, formally the Kingdom of Cambodia, is a country of Southeast Asia, on the Gulf of Thailand, bordering Thailand, Vietnam, and Laos. As a country, it has also been called Kampuchea, Khmer Republic, Democratic Kampuchea and People's Republic of Kampuchea.
Its capital is Phnom Penh.
Ethnically, the major part of its population considers itself Khmer. Prior to being made part of French Indochina, it was the Angkor Empire, dominant in its region between the 11th and 13th centuries. It declined under attacks from Thai and Cham peoples; the Cham were a major part of what is now Vietnam.
