Yejju (), also spelled Yeju, was a historical province of the Ethiopian Empire located in modern day North Wollo Zone. Yejju was initially located near a "Kewet," and was first mentioned in Shihab ad-Din's Futuḥ al-Ḥabash, which described a population of Christians. During the 16th century Oromo expansions, they were assimilated as a sub-clan of the Barento branch of Oromo people through "Meedhicca, Mogasa, and Gudifacha," adopting their language and becoming one of the northernmost communities of Oromo people residing in Ethiopia. This is compounded by the fact the Yejju were not mentioned by Abba Bahrey of Gamo as a sub-clan of the Oromos during the reign of Sarsa Dengel.
History
The Yejju were ruled by the "Warra Sheik," or descendant of Sheikh Omar. Sheikh Omar was a Yemeni Islamic religious leader who married Woyzero Rajiya, a daughter of a noble man of the Yajju district. The descendants of Sheikh Omar were, thus, most commonly refer to as Wara Sheh, meaning "Sons of the Sheikh," Throughout the era, different ethnic groups, clans, and communities made short-term alliances to acquire economic advantage and political power. Due to their native origin, the Yeju spoke Amharic and "adapted themselves more readily and rapidly."
As early as 1890, under the reign of Menelik II, the homeland of the Yejju was organized into an Ethiopian province (awrajja) named after them. It was bordered by the Alewuha River to the north, separating it from Raya Qobbo awrajja, the Mille River to the south, separating it from Were Babu district, the Afar Depression to the east, and the highlands of Ambassel to the west. Woldiya served as its capital city. With the adoption of ethnic federalism in 1994 and the abolishment of the awrajja administrative structure, Yejju was divided between the districts of Habru, Woldiya town, and the mid-altitude portion of Guba Lafto. Due to the assimilation of Yejju Oromos into the dominant Habesha culture during the 20th century, the descendants of the Yejju, presently found in the Amhara Region, identify as Amharas.
