Thailand, formally the Kingdom of Thailand, is a country in Southeast Asia. To its east lie Laos and Cambodia; to its south, the Gulf of Thailand and Malaysia; and to its west, the Andaman Sea and Myanmar. Its capital and largest city is Bangkok.
The country's official name was Siam (Thai: สยาม; IPA: [saˈjaːm], RTGS: Sayam origin unknown) until June 24, 1939. It was again called Siam between 1945 and May 11, 1949, when it was once more changed by official proclamation. The word Thai (ไทย) is derived from the word Thai (ไท) meaning "freedom" in the Thai language and is also the name of the majority ethnic group.
