Augustine's Letters 83-130 were written between 408 and 412, during a time when North Africa was in an uproar over the necessity to resolve the Donatist schism and the imperial government's role in this process. Augustine exchanged correspondence with clergymen and laity, both Catholic and Donatist; in addition, he responded to requests for pastoral advice from ascetically minded men and women, as well as pleas for social justice.
