Cercle was the smallest unit of French political administration in French Colonial Africa that was headed by a European officer. A cercle consisted of several cantons, each of which in turn consisted of several villages, and was instituted in France's African colonies from 1895 to 1946.
At the bottom of the European administration the "Cercle Commander" ("commandant de cercle") was subject to the authority of a District Commander, and the government of the colony above him, but was independent of the Military structure (outside of Military areas, e.g. modern Niger and Mauritania prior to the Second World War). Below the "Cercle Commander" was a series of African "Chefs de canton" and "Chefs du Village": "chiefs" appointed by the French and subject to removal by the Europeans. As well, the "Cercle Commander" made use of a large number of servants, employees, and African officers such as the "Gardes-de-cercle" police, any military units seconded to them by government authorities, and sub administrators such as the Precepteur du marché trade inspectors, etc.
Cercle Commanders and District Commanders were also the chief judges of the Indigénat legal code in the area they commanded. Commanders were expected to make regular tours of their areas to enforce policies, rule on cases, extract taxes and Prestation labor and implement political and economic projects of either the colonial governor, the French Overseas Ministry, or of their own creation.
The commandant de cercle, or any white man in practice, was free to impose summary punishment for any of 34 (later 12) vague headings of infractions of the code: from murder down to 'disrespect' of France, its symbols, or functionaries. These could range from fines, to 15 days in prison, executed immediately. While the statute stated that all punishments must be signed by the colonial governor, this was almost always done after the fact. Corporal punishment was outlawed, but still regularly used. And while reforms were periodically placed upon these powers, in practice they became common and arbitrary. Over 1,500 officially reported infractions were punished under the indigénat in Moyen Congo in 1908-09 alone.
In addition, native sub-officials, such as the appointed local chiefs, made use of forced labor, compulsory crops, and taxes in kind at their discretion. As the enforcers of the indigénat, they were also, in part, beneficiaries. Still, they themselves were quite firmly under French authority when the French chose to exercise it. It was only in 1924 that chiefs du canton were exempted from the Indigénat, and if they showed insubordination or disloyalty they could still (as all Africans) be imprisoned for up to ten years for 'Political offences' by French officials (subject to a signature of the Minister of Colonies).
