Italian was the official language of Eritrea during Italian colonisation. Italian is today used in commerce and it is still spoken especially among elders; besides that, Italian words are incorporated as loan words in the main language spoken in the country (Tigrinya). The capital city of Eritrea, Asmara, still has several Italian schools, established during the colonial period. In the early 19th century, Eritrea was the country with the highest number of Italians abroad, and the Italian Eritreans grew from 4,000 during World War I to nearly 100,000 at the beginning of World War II.
