Abstract Kenya began its democratic era after its declaration of independence and the adoption of its first constitution in 1963. However, this supreme norm of the country would undergo countless reforms by the political elites from the very beginning, mostly to satisfy the partisan demands of the political leaders of the moment. These reforms succeeded in transforming the initially democratic model into an authoritarian, one-party system. After two decades of corruption and abuses of power, political changes in the country, and a wave of democratization after the fall of the Berlin Wall fueled the popular clamor for constitutional change. This article analyses the development of the constitution-making process, which began with the first constitutional amendments introduced to the constitution of the independence, as well as the main factors that led to the rejection of a new draft constitution in the ratification referendum held on November 21, 2005. A key element contributing to the failure of the whole process is the strong influence of political forces in the process, all using partisan methods to achieve perceived political advantages.
