The Scramble for Africa refers to the period between roughly 1884 and 1914, when the European colonisers partitioned the – up to that point – largely unexplored African continent into protectorates, colonies and ‘free-trade areas’. At the time the colonisers had limited knowledge of local conditions and their primary consideration was to avoid conflict among themselves for African soil. Since no one could foresee the short-lived colonial era, the border design – which endured the wave of independence in the 1960s – had sizable long-lasting economic and political consequences. The Scramble for Africa resulted in several large countries characterised by highly heterogeneous geography and ethnically fragmented populations that limit the ability of governments to broadcast power and build state capacity.

The First World War resulted from festering imperial rivalries and ethnic conflicts in central Europe that set in motion a series of disastrous events and decisions. Europe had developed a system of alliances that divided the continent in two. Democratic Britain and France, along with the Russian Empire, had formed the Triple Entente. Central Powers were comprised of the new German Empire, Austria-Hungary, and Italy. The assassination of the heir to the Austro-Hungarian throne by a Serbian nationalist triggered the world war in August 1914.
