In the 18th century, the local colonial administration of French Guiana represents a particular configuration of administrators, employees or others, simply people with their own perceptions, demands and individual perspectives while working within a common social space. In the middle of this colonial administration required by Colbert, the supreme, then superior council represents a point of agreement between the main officials and the most important inhabitants. The superior council of Cayenne is at the same time a place of power and of representation, and thus becomes the centre of issue of power and the theatre for the network of influence. If these phenomena escape most of the time from the ascendency of the classical archivist production, they are not less interesting to analyse. Especially corruption, considered here as the pursuit of a private interest at the expense of a general interest, poses the problem of the separation between public sphere and private sphere.
