The Early History of Rome (Barnes & Noble Library of Essential Reading): Books I-V of the Ab Urbe Condita by Livy
Livy's "Early History of Rome" tells of a small monarchical state's struggle to survive. It tells the story of the overthrow of the kings and the development of the Roman Republic. It depicts the qualities that allowed the early Romans to overcome internal disputes and foreign enemies and to recover after the nearly total destruction of their city in 390 BC. Livy writes with fairness, humanity, and an irresistible enthusiasm for the courage, honesty, and self-sacrifice that exemplified what it was to be Roman.
