evidence: Chiengi or is a historic colonial boma of the British Empire in central Africa and today is a settlement in the Luapula Province of Zambia, and headquarters of Chiengi District. Chiengi is in the north-east corner of Lake Mweru, and at the foot of wooded hills dividing that lake from Lake Mweru Wantipa, and overlooking a dambo (marshy plain) stretching northwards from the lake, where the Chiengi rivulet (the origin of the name) flows down from the hills.[1] [...] Chiengi Boma was probably the first colonial post in what was to be called North-Eastern Rhodesia (it was still referred to as part of 'Zambezia' at the time), and was one of the most remote outposts of the British Empire, a lonely posting which sent more than one colonial officer mad.[1] For a number of years the boma was removed to the Kalungwishi River, and during this period the Belgian colonial authorities in Pweto, just across the border in DR Congo, controlled the northern end of the lake including the western extremity of Chiengi District, the so-called Lunchinda enclave west of the Lunchinda River. The British then re-established the boma at Chiengi but the eventual outcome of de facto Belgian control of the Lunchinda enclave led to it eventually being ceded to DR Congo by Zambia—see the article on the Luapula Province border dispute.
