The Limoges Cathedral Chapter opens an interesting window for the examination of the local impact of the regulations drawn up by Louis the Pious at the Council of Aix in 816. Its history is documented by 54 charters found in the cartulary issued between 817 and 988. After examining this corpus of charters, the relations between the canons and the bishop and the features of the management of the patrimony, the aim here is to show that this community is well attested in the ninth century, with all its dignitaries. It is difficult to know how many canons made up the chapter, but it is certain that most of the canons were recruited from the regional aristocracy. Common life was present there at least through the sharing of meals, but it is not known whether the dwellings were individual or communal. The contours of canonical life are therefore specified, within this group of clerics serving the major church, without it being really possible to say whether this proceeded from the reforms of 816 or whether it was an extension of earlier customs. In any case, the reform does not seem to have brought about any major change. The theme of living together was not a controversial subject at the time, and there were no breakdowns of any kind during the tenth century.
