Annalists (from Latin annus, year; hence annales, sc. libri, annual records), is the name given to a class of writers on Roman history, the period of whose literary activity lasted from the time of the Second Punic War to that of Sulla. They wrote the history of Rome from the earliest times (in most cases) down to their own days, the events of which were treated in much greater detail. Annalists were different from historians, in that an annalist was more likely to just record events for reference purposes, rather than offering their own opinions of events. There is, however, some overlap between the two categories and sometimes annalist is used to refer to both styles of writing from the Roman era.
