According to the history of Jackson in Requiem for a Nun, "the Frenchman" alternated with "the Spaniard" for possession and control of the area (81). Historically, this land was claimed and ruled over by France several different times during the 18th century.
In Requiem for a Nun the people who were formerly enslaved in Jackson and elsewhere are referred to, tangentially, in the negative characterization of the Federal officials who administered the post-war attempt at Reconstruction: they are the "freed slaves" whose votes those "carpet-baggers" know how to manipulate (87). Presumably this group also includes the students who attend Jackson's three "College[s] for Negroes"; the colleges are mentioned in the text but not the people who attend them (87).
The history of Jackson in Requiem for a Nun treats the "Federal provost-marshals" who came to the defeated South charged with protecting the rights of the slaves who were emancipated at the end of the Civil War according to the then-popular pro-Southern accounts of Reconstruction: the elections they preside over are described as corrupted by carpetbaggers (87).
In Requiem for a Nun the jail is used as the "provost-marshal's guard-house" during the Union occupation of Jefferson during the Civil War (196); a provost marshal is in charge of a unit of military police.
This man and "his marshal" are on hand when Mohataha and her people leave Yoknapatawpha for the "Indian Territory" in the "West" - presumably to make the Chickasaws' 'removal' official, though Requiem for a Nun does not specifically mention the Removal (170).
In Requiem for a Nun these "young men from Brooklyn (exchange students at Mississippi or Arkansas or Texas universities)" wave "tiny confederate battle flags" at college football games (194). Calling out-of-state students "exchange students" is an odd formulation, suggesting that 'the North' they come from is essentially a different country - as of course it would have been to the Confederates who originally carried those flags during the Civil War.
She is the "European mistress" of the "Mohammedan prince" in Requiem for a Nun who built the "hideaway where Temple Drake and Gowan Stevens honeymoon (122).
In Requiem for a Nun this "female slave child" sits next to Mohataha in her wagon, holding "the crusted slippers" that originally came from France (170).
Owned by Mohataha, the matriarch of the Chickasaws in Requiem for a Nun, this "Negro slave girl" holds "a French parasol" over her master when Mohataha comes to town in a wagon (169).
