The first telegraph line in Ethiopia was constructed in the years 1897 - 1899 between the cities of Harar and the capital Addis Ababa. This was extended in 1904 by a line that ran from Addis Ababa through Tigray into Eritrea and to Massawa; and the next year by a line again from Addis Ababa to Gore in the province of Illubabor and Jimma in Kaffa.
The first telephones were brought by Ras Makonnen from Italy in 1890, and connected between the Palace and the Imperial treasury; the sound of disembodied voices frightened the local priests, who thought it was the work of demons. The Emperor Menelik II responded to their protests with disdain, and later used the telephone to give orders to his provincial governors. Emperor Haile Selassie had begun the process of introducing radio transmitters to the country for civilian and military use in the years before the Italian invasion.
