The birr (Amharic: ብር) is the unit of currency in Ethiopia. It is subdivided into 100 santim.
In 1931, Emperor Haile Selassie I formally requested that the international community use the name Ethiopia (as it had already been known internally for at least 1,600 years[2]) instead of the exonym Abyssinia, and the issuing Bank of Abyssinia also became the Bank of Ethiopia. Thus, the pre-1931 currency could be considered the Abyssinian birr and the post-1931 currency the Ethiopian birr, although it was the same country and the same currency before and after.
