The Russian explorer Alexander Bulatovich visited Bilo 8 November 1896. At the time, it was a crossroads for caravans travelling between south-western Ethiopia and Gojjam on their way to the traditional Ethiopian port of Massawa. Although it was in the territory of Dejazmach Demissew Nassibu, it was not part of it; instead it was under the rule of a nagadras or governor of its marketplace. Bulatovich noted that the settlement had fewer than 300 permanent residents and, in light of the colonial developments along the Red Sea coast, most of south Ethiopia's trade had shifted to the routes through Harar to the French port at Djibouti and the British-held port at Zayla. The opening of the Franco-Ethiopian Railway at Dire Dawa in 1901 drove still more of the trade along these routes at the expense of Bilo and nearby Leika.
