The next 25 years of the changing power capabilities of Algeria, Egypt, Ethiopia, Nigeria and South Africa (the ‘Big Five’) are being explored in this paper. Of these countries, Ethiopia and Nigeria are forecast to increase their power capabilities, whereas Algeria, Egypt and South Africa are expected to stagnate or decline. Of the Big Five, two currently punch above their weight – one that is rising, Ethiopia, and another whose growth is stagnant, South Africa. If Nigeria were able to take the necessary steps that would see far-reaching changes to the governance issues and social challenges that currently beset the country, it could become Africa’s lone superpower.
