History
The grave of a contemporary of Imam Ahmad Gragn named Ashab 'Utman, whom tradition says was an important missionary of Islam in what became the Arsi Zone, lies near Tijo. He is said to have been killed by the Ogaden warrior Atalibo and was then cursed for this deed by Imam Ahmad's successor Emir Nur ibn Mujahid. The Hadiya clans Dooda, Weege, and Malge claim him as their ancestor. [2] Ashab 'Utman's cupola-shaped tomb, which Braukämper states "was presumably erected in the 1880s", over the following decades became an important focus of local Muslim attention. [3]
Tijo served as the administrative center for Arsiland during the Italian occupation. [4]
Records at the Nordic Africa Institute website provide details of a primary school in Tijo during the year 1968. [5] Tijo is composed of several small villages which include Bura Jallee, Wajiifi Titte, Digeluu, Naannawa, and Kallaa.
