Ein Forschungsreisender als Notbehelf: Hermann von Wissmann und der erste Überseeeinsatz des Deutschen Reichs (1889-1891)

When the German government faced for the first time an irregular war in German East Africa in 1888, it realised that it did not have the necessary means for such a conflict. Hermann Wissmann, an explorer, was therefore given the mandate to form and lead a force of mercenaries that was bound to him personally on the basis of contracts. Although Wissmann was successful in crushing the disturbances, the government of the Reich refused to give him a leading administrative position in the new formed protectorate subordinate directly to the Kaiser. It feared that the entrepreneur of violence, which had up to then been backed up, would not accept the regulations of colonial rule that should be implemented. Soon, however, it became clear that due to entrenched local views on sovereignty and legitimacy it would be difficult to transfer the western European concept of the monopoly of the state on violence to Africa.
