The Apostolic Prefecture of Lower Congo, an exempt jurisdiction (i.e. directly subject to the Holy See), was established in 1640 on colonial territory split off from the then
Roman Catholic Diocese of São Paulo de Loanda in then
Portuguese Congo. On 22 November 1886, it lost territory to establish the
Mission sui juris of Belgian Congo (alias Belgisch Kongo or Congo Belge, the official names of the meanwhile explored Belgian colony). Still in 1886, the remainder was renamed as
Apostolic Prefecture of Lower Congo in Cubango In 1900 it lost territory again, to establish the
Mission sui juris of Lunda (alias Mlundi). On 4 September 1940, it was suppressed and its territory merged into the
Roman Catholic Archdiocese of Luanda, in then still Portuguese
Angola. == Incumbents ==
