How did they geet eritrea name?

Answer 1

The name "Eritrea" is derived from the ancient Greek name for the Red Sea, "Erythra Thalassa" (meaning "Red Sea"). During the late 19th century, when Italy colonized the region, they adopted this term to refer to their newly acquired territories in the area. The name was officially used when Eritrea became an Italian colony in 1890, and it has remained since Eritrea gained independence in 1993.
