This paper examines how Africanization policy re-engineered the political engagements of the Asian minority community in Nairobi City, Kenya, between the period 1963 and 1978. The paper is anchored on rational choice and liberal democratic theories. Rational choice theory as advanced by Adam Smith, argues that human desires are self-seeking and always lean towards self-interest. On the other hand, liberal democracy theory as advanced by John Locke argues that natural law guarantees every individual right to life, liberty and protection of private property. This paper therefore uses these two approaches to show that Asians have been engaging in political participation in Nairobi City as a matter of self-preservation and/or as a way of championing for protection of their natural rights in case of an imminent violation. The key objectives of the paper are to: examine how politicization of citizenship and Asian identity question impacted on Asian participation in elective politics immediately after independence in Nairobi City; to establish the political implication of Africanization programmes on the Asian community; and thirdly to discuss the ramifications of Africanization policy on Asian participation in elective politics of Nairobi City. The study adopts a descriptive survey design and utilizes both primary and secondary data. Similarly, the study utilizes both stratified and purposive sampling techniques to identify research informants. The study reveals that Africanization policy was such an emotive issue among the Asians not only in Nairobi City, but also across the country where they lived as a minority community. No wonder, the policy impacted negatively on their participation in elective politics between 1963 and 1978.
