Conflict is a threat to human life. It arises when two or more parties have incompatible goals. This study sought to assess the factors influencing continuous conflict between the Tigania and Tharaka communities in Meru, Kenya. The study was motivated by the need to investigate the root causes of the continues conflict between related communities which coexisted for ages only to start clashing in the resent past yet the government security mechanisms and indigenous institutions that traditionally managed conflicts in the community contained the conflict in the past. Johan Galtung’s conflict theory and analysis that seeks to understand the root causes of conflicts, structure and dynamics of conflicts and its actors with an aim of suggesting possible resolution strategies was used. The study adopted a descriptive study design. Purposive sampling was used to select the sample size. Questionnaires were used to collect data from both the affected people in Tigania and Tharaka Districts. An interview schedule was also administered to collect data about the conflict from among opinion leaders. It was revealed that there exists continuous conflict between Tigania and Tharaka communities of the greater Meru region. Access to and control of scarce resources was found to be the main cause of the conflict.Other factors causing the conflict included politics of self interest, border disputes, land adjudication and government policy. Impacts of the conflict were; disruption of economic activities, environmental degradation, displacement of people, physical harm and death. Intervention mechanisms to end the conflict included establishment of Njuri Ncheke border arbitration committee and peace building initiatives through public gatherings.
