There are numerous political crises in Africa, albeit one needs to stress that they do not touch all African states. This chapter discusses four types of crises: secessions, coups, electoral violence, and terrorism. Despite their different shape, they all can potentially challenge or even undermine state institutions, dwarf the economy, and pose a threat to the population. Despite them being the children of the weakness of states, there is, however, also evidence showing that secessions, coups, and electoral violence might lead to more legitimate governments and advance democratization in the long run. Such news is missing with regard to terrorism.
