We possess in full two of the historical works that have been convincingly ascribed to Sallust, the monographs, "Bellum Catilinae" and "Bellum Jugurthinum". We have only fragments of the third work, his Histories. There is less agreement about the authorship of some other works that have, at times, been attributed to him. In "Bellum Catilinae", Sallust outlines the conspiracy of Catiline, a brash and ambitious patrician who tried to seize power in Rome in 63 BC. In his other monograph, Sallust used the Jugurthine War as a backdrop for his examination of the development of party struggles in Rome in the 1st century BC. The "Historiae" describe in general the history of the years 78–67 BC.
