When Fascist Italy imposed the Italian lira in occupied Ethiopia in 1936, it decided upon a rate of 3 lire = 1 thaler.
The Italian government declared this practice illegal, but in 1938 issued a new banknotes "lira AOI" at a better rate of 4.5 lire = 1 thaler for citizens who would willingly exchange their silver coins at the Bank of Italy.
In occupied Ethiopia, the lira replaced the Ethiopian thaler (issued by the National Bank of Ethiopia) whilst in Italian Eritrea it replaced the Eritrean tallero, a silver coin minted in Italy.
It also briefly replaced the East African shilling in British Somaliland under Italian occupation between 1940 and 1941, when the Italian East African lira was offered at a rate 13 lire = 1 thaler.
The Italian East African lira was seen as a possible bribery, and it was immediately replaced by the East African shilling in 1941, when the United Kingdom gained control of Italy's colonies, at the rate of 1 shilling = 24 lire.
