Pyeongtaek is a city in Gyeonggi Province, South Korea. Located in the southwestern part of the province, Pyeongtaek was founded as a union of two districts in 1940, during the Goryeo dynasty. It was elevated to city status in 1986 and is home to a South Korean naval base and a large concentration of United States troops. The South Korean government plans to transform Pyeongtaek city to an international economic hub to coincide with the move of the United States Forces Korea (USFK) to Pyeongtaek. During the Korean War, it was the site of an early battle between U.S. and North Korean forces, the Battle of Pyongtaek. It is the location of Pyeongtaek University.

Korean is the native language for about 81 million people, mostly of Korean descent. It is the official and national language of both North Korea and South Korea. The language has notable differences in each of the Koreas, in part owing to different official standardizations of the language. They are still largely mutually intelligible, however. South Korean newspaper Daily NK has claimed North Korea criminalizes the use of the South's standard language with the death penalty, and South Korean education and media often portray the North's language as alien and uncomfortable.
