found: Leopoldian Sudan (Bahr-el-Gazal), then Lado's Enclave (1894-1903), via Heraldry of the world website, July 23, 2011(Although of short-lived existence, a territory situated in Sudan was the object of an attempt of colonisation led by Belgian troops acting on the orders of King Leopold II: it concerns the "leopoldian Sudan", more known under the naming "Lado's enclave", that was supposed to become an integral part of Congo. By the signature of two successive agreements (in May 12, then in August 14, 1894), the British Government declare, in the name of Egypt, to let King Leopold II have a territory called "Lado's enclave", taken from the Bahr el Gazal's Sudanese province (the "River of Gazelles"), and being bounded by the latitudes 5°30ʹN and 30°W. Following the Fachoda incident, which set British troops against French at the edge of the Nile, the sovereign power of Egypt on Sudan was however restored and obliged Leopold II to give up Lado's enclave in 1903, with the exception of Mahagi.)
