This article is proposing a regime-oriented approach to explain the variation on the African continent. Democracies, party-based regimes, and military regimes are surely different from each other, but they have a degree of depersonalisation in common that is not found in personalist regimes. For the latter type, term limits are a question of regime survival.
Personalist rulers will therefore seek to amend or ignore constitutions, but their success will depend on the cohesion of their ruling coalition. The argument will be illustrated with two case studies: Togo and Tanzania.
