The birr is the unit of currency in Ethiopia. Before 1976, dollar was the official English translation of birr. Today, it is officially birr in English as well.
In 1931, the Emperor of Ethiopia, Haile Selassie I, formally requested that the international community use the name Ethiopia (as it had already been known internally for at least 1600 years) instead of 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.
The Ethiopian Birr is the second-most-used currency in Africa with 88 million users, after the Nigerian naira. 186 billion birr were in circulation in 2008 ($14.7 billion or €9.97 billion).
