Power-sharing arrangements address competition over power, resources, and democratic deadlock. These arrangements, which often lead to the formation of coalition governments or governments of national unity, are typically established by political parties with conflicting interests. Africa has witnessed various power-sharing arrangements concluded between incumbent governments and opposition parties due to electoral irregularities. The impacts of these arrangements have been studied from multiple perspectives. Most studies have focused on their effects on socio-economic development, democracy, security, and peace. However, the impact of these arrangements on the protection of human rights has been addressed in only a few studies. This highlights the importance of examining the implications of power-sharing arrangements in the context of human rights protection in Africa. Among the three countries under consideration, only Tanzania Zanzibar currently has an active government resulting from power-sharing schemes. In Kenya and Zimbabwe, governments arising from power-sharing arrangements were transitional. This chapter explores the implications these arrangements had in Kenya and Zimbabwe and continue to have in Tanzania Zanzibar, particularly regarding the protection of human rights.
