These societies bear individual names and operate separately. In fact there is no central organization and the term Société Congo only designates the kind of society. The purpose of these organizations is fourfold. First, they are cooperative labor groups; second, the members are afforded protection; third, they are mutual benefit societies; and fourth, they provide social entertainment.
