Eritreans are the native inhabitants of Eritrea, as well as the global diaspora of Eritrea. Eritreans constitute several component ethnic groups, some of which are related to ethnic groups that make up the Ethiopian people in neighboring Ethiopia and people groups in other parts of the Horn of Africa.
the Eritreans I’ve met have all been light skinned with thin facial features...seemingly a lot of arab intermingling, forced or otherwise....Ethiopians are similiar in that half their population have thin builds and facial features and the other half darker skin, more typical african features...
