Historically, the subject of this study, the Qa/lu institution, was widely used amongrnthe Oromo as important religious institution. Its significance as a religiousrninstitution, however, declined through time as the 01'01110 started to adhere to Ilell'rnforms of religious beliefs including Christianity and Islan1. Yet, the Qallu institutionrndidn't weather away from the Oromo sOCiO-cllltliral life. Though its religiollsrnsignificance waned through time, it continued to survive in other dimensions, ./01'rninstance, as a crucial institution for conflict resolution, magical healing and peacernbuilding. It is these surviving dimensions of Qallu institutions and the ritllalsrnaccompanying them, which became the concern of my study. In order to analyze therndimensions of the Qallu and the accompanying rituals, I selected the Warra ElemornQallu institution in West Shewa, because this Qallu trad ition represents the mostrnuntouched in terms of scholarly investigation. Of the Warra Elemo Qallu Intu itionsrnwhich are four in number, this research focuses on the Inikka Elemo Qallu Institlltion.rnIn order to obtain the necesswy data for my research. overwhelmingly I relied onrnqualitative method of data gathering. The qualitative data gathering tools elllployedrnin the study include interview, participant observation and focus group discussion.rnBesides, photographic and video graphic methods were IIsed to capture the ritllalrnperformances, the scenes (selling!», and the participants. AI/ these were cormiJoratedrnby review of secondary sources.rnThe finding of this research is that Qa/lu as an institlltion among the Macha oj WeslrnShewa is still a living institution. In spite of the fact that the people of the arearncurrently adhere to Christian religion, the Qallu still plays an important role in thernlife of the society without, however, pretending to be a substitute for the two dominantrnreligions. The Qa/lus especially serve as key mediators in conflict and traditionalrnhealers possessing extraordinary power.rnThe thesis is organized as fo llows: the 1'{ chapter deals with the proposal of the stlldyrnand background. The second and third chapters are about the works of others thatrnare related to this culture, i.e., literature review and conceptualframe work. In this. itrnis believed that sufficiently er:ough works have been assessed to serve the pllrposern. Chapters four to six are the main body parts of the sludy. In these. the ritllal hOllses.rngenealogy of the qallus, the rituals, and the social roles of the qallu have beenrnanalyzed based on observations and interviews. Both methods were used to analyzernthe above mentioned points parallel to one another.rnThe last chapter seven is devoted to summOfY, conclusion and Oromo glosswy. Inrnthis, a trial was made to sum up important pOints and Ihe outcome of the study. Thernqallu is the most important person in the society and his institution serves the societyrnat best. The religions part gives people spiritual sati!>jaction. The social rolesrnmaintain peace among the society and the individuals. II Ilt'eserves Orolllll (,lIllttl'£'. Itrnmay also bring unity among the Oromo. So, it may be concluded that it is 1I /il'ingrnculture thai deserves to be maintained.
