🧠 Explanation:
The country of Myanmar was formerly known as Burma. This name was officially changed by the military government in 1989, with "Myanmar" reflecting the majority Bamar (Burman) ethnic group's name in the Burmese language. The change aimed to foster national unity and align with local pronunciation, though "Burma" is still used in some contexts internationally.
