Potential Historical Origin of Tribalism in Multiparty Democracy in Africa 1963-2023: A Comparative Analysis of Kenya and Tanzania

Ethnicity has remained one of the most influential factors shaping political development in Africa since independence. While ethnic identity is a natural social phenomenon that provides individuals with a sense of belonging, its politicization has often generated divisions, conflict, and unequal distribution of resources. In many African countries, political competition has increasingly been organized around ethnic affiliations, resulting in what is commonly referred to as tribalism.
The origins of tribalism in Africa can be traced to both pre-colonial and colonial periods. Pre-colonial African societies were organized around kinship, clans, and ethnic communities that maintained distinct cultural, linguistic, and territorial identities. Although these identities existed, they rarely formed the basis for large-scale political competition. The advent of colonialism transformed ethnic identities by creating administrative boundaries, introducing indirect rule, and promoting differential access to education, employment, and economic opportunities among communities.
Following independence in the 1960s, African leaders faced the challenge of transforming ethnically diverse societies into unified nation-states. While some countries successfully promoted national cohesion, others experienced persistent ethnic rivalries that became deeply embedded in political processes. The introduction of multiparty democracy in the late twentieth century further intensified ethnic political competition in several African countries, as political parties often mobilized support along ethnic lines.
Kenya and Tanzania provide a useful comparative framework for examining the historical origins of tribalism in multiparty democracy. Both countries share several similarities, including British colonial rule, ethnic diversity, geographical proximity, and independence in the early 1960s. However, their experiences with ethnicity and national integration differ significantly.
Kenya has experienced recurrent ethnic tensions, ethnic voting patterns, and politically motivated conflicts associated with electoral competition. Since the reintroduction of multiparty politics in 1991, ethnicity has remained a major determinant of political alliances, voting behavior, and distribution of political power.
Conversely, Tanzania has generally maintained a higher level of national cohesion despite having over 120 ethnic groups. The country's adoption of Kiswahili as a national language, the nation-building philosophy of Ujamaa under Julius Nyerere, and policies discouraging ethnic mobilization have often been cited as contributing factors to its relative success in minimizing tribal politics.
This study seeks to investigate the historical origins of tribalism in multiparty democracy by comparing Kenya and Tanzania between 1963 and 2023. Through a historical and comparative approach, the study aims to identify the factors that explain the different trajectories of ethnic politics in the two countries.
