After much negotiation, it was definitely arranged on May 11 , 1888, that the activities of the Algiers Mission should be confined to Tanganyika, the seat of an Apostolic Vicariate, but that the priests sent there should be Belgian by nationality, and that there should be created the Apostolic Vicariate of the Congo, entrusted to the Pèresde Scheut and to the African Seminary established by the King at Louvain .
