This paper aimed at examining ethnicized politics in Kenya and their contribution to elections and public governance from independence to date. This paper looks into the historical context of ethnicized politics in Kenya and events that have entrenched this undesirable factor of Kenya political landscape from colonialization to date. The paper demonstrates how political elites take advantages over their ethnic groups to form political parties that enable them to occupy positions of leadership as tribal chiefs, As politicians they purport to advance their ethnic group’s political interest but their aim is to form governments and to consolidate power. The paper shows that ethnicized politics have led to marginalization of small tribes and their subsequent resentments that have resulted to major conflicts like the post elections violence of 2007, the conflicts witnessed in 2017 and the post elections tensions of 2022. Ethnicized politics have led to demonstrations and political violence in Kenya leading to loss of life and property, human rights violation and abuse of the rule of law. The paper recommends de-escalation of ethnicized politics and enhanced national cohesion. It advocates for granting of national jobs to individuals based on meritocracy rather than ethnicity.
