A.H.J. Greenidge 
History of Rome from 133 B.C. to 70 A.D. (1904) [PDF ebook] 
From the Tribunate of Tiberius Gracchus to the End of the Jugerthine War

First published in 1904, this volume began what was to be the magnum opus of the highly regarded Classical scholar, A.H.J. Greenidge. Though published posthumously, the work stands alone as a valuable contribution to Classical history. Beginning with a socioeconomic history which exposes the conditions preceding and determining the great conflict of interests to follow, Greenidge then explores the story of Rome from Scipio Aemilianus and the Gracchi brothers until the second election of Marius to the consulship.
