In the spring of 1911 a French expedition occupied Fez. This action, added to the growing discontent in Germany over the Moroccan question, tempted the German Government at the beginning of July to an abrupt act. The Brothers Mannesmann, a German firm at that time very active in European financial circles, claimed that they had large interests in a harbour on the Atlantic seaboard of the Moroccan Coast and in the hinterland behind it. This harbour bore the name of Agadir. Herr von Kiderlen-Wächter, the German Foreign Minister, raised this point with the French. The French Government fully realised that the advantages they were gaining in Morocco, justified Germany in seeking certain colonial compensations in the Congo area. The German press on the other hand was indignant at exchanging German interests in the moderate climate of Morocco for unhealthy tropical regions of which they had already more than enough. The questions involved were complicated and intrinsically extremely unimportant. The French prepared themselves for a prolonged negotiation. So far as the harbour and hinterland of Agadir were concerned, there seemed to be no difficulty. They denied altogether the existence of any German interests there. They said there was only a sandy bay untouched by the hand of man; there was no German property on the shore, not a trading establishment, not a house; there were no German interests in the interior. But these facts could easily be ascertained by a visit of accredited representatives of both countries. Such a visit to ascertain the facts they professed themselves quite ready to arrange. They also courted a discussion of the frontier of the Congo territories.
