The present monograph gives voice to the representatives of various social science disciplines who use the expression `actor in politics' according to the requirements of their respective approaches. They nevertheless arrive at an interesting and, to a great extent, impressive unity in diversity. What the texts show is the encounter of African actors and their agency with external actors and factors. Another connection uniting the contributions is the fact that they address the impact political actors outside the official or formal domain can and do exert on the respective societies. Informal politics and informal political actors and their entanglement with the official and formal domain of politics are among peculiarities of current African politics. But informality in politics and entanglement of formal and informal political actors might also hint at the future of politics and political order in general.
