Near Nejo at the hill of Guté Dili, on 14 October 1888 the joint forces of RasGobana Dacche and Moroda Bekere defeated the invading army of Khalil al-Khuzani, an officer of the Abdallahi ibn Muhammad who had invaded Wellega. At the time, Nejo was a trading center of the Sibu Oromo. DejazmachGebre Egziabher moved his residence from Nekemte to Nejo, where around 1893 he built the church of Kidane Mihret, the second Ethiopian Orthodox church in Sibo province; priests for the church were recruited from Shewa. In 1904 Onesimos Nesib arrived at Nejo to establish a mission, together with his wife, his children, and a group of associates including Aster Ganno. He had originally gone to Nekemte, but learning that Dejazmach Gebre Egziabher had relocated to Nejo followed him there. The Dejazmach invited Onesimos to settle next to his gebbi, gave him a large piece of tax-free land, and built him a house and a school. By September of that year, Onesimus had 20 students in his school. In November 1905 Dejazmach Gebre Egziabher moved his residence back to Nekemte, and he took Onesimus along. The school had as many as 68 students, but closed when Onesimos and Aster left. About this time, Nejo had become a significant market center for gold from the nearby Abay and Dabus rivers. "The stock-in-trade is a small neatly worked basket," wrote Herbert Weld Blundell who visited the area in 1905, "containing pebbles ground to equal the weights required for weighing out the gold, a small copper balance, and finally, the gold-dust in quills The amount of gold exported from Nejjo has been put by engineers living there at about £80,000 a year, and the tribute of the king is about one-half of this." The Evangelical mission was revived in 1927, when Pastor Martin Nordfeldt and his family arrived from Nekemte in July of that year. During their stay, the Nordfeldts wrote an Oromo grammar which was printed in the Swedish journal Le monde oriental. Nejo became something of a mining center in 1929, when important occurrences of gold were found in the area. Although the Evangelical church had survived the Italian occupation, despite being converted to a Roman Catholic church, after their expulsion Fitawrari Danye and his soldiers allegedly vandalized the building, stealing everything of value, knocking the altar to pieces, and used the church building as a stable. The other mission buildings were likewise pillaged. Despite this, by the late 1940s the mission was once again in operation. A 26-year-old farmer, Henok Jonatan, was arrested by government forces in Nejo on 16 March 1995, suspected of being active for the Oromo Liberation Front. He is believed to have been tortured, along with nine other Oromo prisoners. Their bodies were discovered 28 April at Mucha Fugiso.
