Early British Administration in the Southern Sudan
During the first decade of the Anglo-Egyptian occupation of the Sudan, the newly formed Condominium Government had slowly established its rule in the Southern Sudan. A way to the south was first cleared through the sudd-choked channels of the Bahr al-Jabal and the Bahr al-Ghazāl Rivers, and administrators and troops soon followed to secure the control of the Upper Nile Valley for Britain and Egypt against the pretensions of other European powers. In 1898 Britain successfully rejected the claims of France to the Upper Nile, but it was not until 1906 that the British Government was able to eliminate the third competitor for control of the Southern Sudan—the Congo Free State. From 1902 to 1906 desultory negotiations were carried on between the British Foreign Office and the representatives of Leopold II, King of the Belgians and Sovereign of the Congo Free State, enlivened only by provocative incidents precipitated by Leopold's agents in the Southern Sudan. Both parties had valid legal and moral claims to the Upper Nile which were supported by the arms of the Force Publique on the one hand and Egyptian and Sudanese troops on the other.
