Khong Chiam district
Khong Chiam (, ) is the easternmost district ("amphoe") of Ubon Ratchathani province of Thailand. History. The area of the district was the central district "khwaeng" of "Mueang" Khong Chiam, which is now Si Mueang Mai district. On 1 January 1957 the three "tambons" Khong Chiam, Huai Yang, and Pho Klang were split off from Khong Chiam to form the Ban Dan minor district ("king amphoe"). On 11 December 1959 it was elevated to a full district. On 14 September 1971 the district was renamed "Khong Chiam", while the former district Khong Chiam was renamed "Si Mueang Mai", as  the historical center of "Mueang" Khong Chiam was in this district. It is thought that the name "Khong Chiam" comes from the word "khong" (โขง) meaning 'chief of elephants' or 'herd of elephants' ("khlong"; โขลง in Thai) and "chiam" (เจียม) from the word "chiang" (เจียง), which means 'tribute'. Overall, it can be meaning 'city with elephants live together in large herds'. Geography. Neighboring districts are (from the south clockwise) Sirindhorn, Phibun Mangsahan, and Si Mueang Mai. To the east across the Mekong River are the Laotian provinces of Salavan and Champasak. Khong Chiam is the easternmost point of Thailand. The  Pak Mun Dam stops the Mun River before it empties into the Mekong River in this district. The Kaeng Tana and Pha Taem national parks are in Khong Chiam District. Administration. The district is divided into five sub-districts ("tambons"), which are further subdivided into 50 villages ("mubans"). The township ("thesaban tambon") Ban Dan covers parts of "tambon" Khong Chiam. There are a further five tambon administrative organizations (TAO).
