Survey evidence indicates that political corruption is more prevalent in Africa than in any other global region, though there is also evidence of considerable variation between countries in degrees of corruption and where it is most likely to be located. Traditional explanations for the frequency of corrupt political behavior emphasized the effects of conflicting values that were a consequence of the imposition of modern forms of bureaucratic government upon societies in which authority rested upon personalized relationships. Contemporary African corruption’s historic roots and its variation across the continent may be the effect of the disjuncture or “incongruency” between colonial and successor postcolonial states and the precolonial political settings upon which they were imposed. Modern neo-patrimonialism is a coping response by rulers and citizens to conditions fostered by economic scarcity and institutional incapacity. Since the 1990s, democratization and liberalization have supplied fresh incentives and opportunities for venal politicians and officials. And even among Africa’s more capable and resourceful states, the institutional fluidity generated by democratic transition and economic reform has opened up possibilities of systematically organized state capture. Consequences of corruption certainly further impoverish poor people, and it is likely that corruption also limits economic growth and distorts government efforts to promote development. It is arguable that in the past, corruption may have helped to facilitate political stability but this is less likely in 2018, as evidence emerges of its corrosive effects on public trust in institutions. African anti-corruption efforts are constrained by the extent to which political power is exercised through patronage but there are instances of successful action, sometimes the byproduct of factional struggles within the political elite. As of 2018, there is no clear evidence of trends in success or failure in the work of African anti-corruption agencies.
