In the Burmese language, Burma is known as either Myanmah or Bama. Since British colonial rule, the country was known in English as "Burma". In 1989, the military government officially changed the English version of the country's name from "Burma" to "Myanmar". The renaming proved to be politically controversial. Opposition groups continue to use the name "Burma", because they do not recognize the legitimacy of the ruling military government nor its authority to rename the country in English.
