In 2012, Mali began a long slide into insecurity and political instability. This chapter reviews the historical roots of that crisis, beginning in the waning days of French colonialism and continuing through periods of socialist nationalism, military rule, and liberal democracy. Mali’s postcolonial state has faced numerous internal and external threats. Some stemmed from hierarchical structures within the country’s heterogeneous population and the conflicts these structures engendered. Others emanated from heavy-handed government attempts to impose order and national identity on this population. Some were posed by other states in the Sahel and beyond. Still others came in the form of non-state actors exploiting state weakness to advance their own political and social agendas. Critically examining the competing narratives about Mali’s ongoing crisis, which focus on neocolonialism, geopolitics, and political institutions, this chapter demonstrates that the origins of the crisis are neither simple nor monocausal.
