The Discourses on the First Ten Books of Titus Livy, often referred to as The Discourses or Discourses on Livy, is the second most well known book after The Prince (which is to say not very) by Niccolò Machiavelli. It covers the first ten books of Titus Livy's Ab Urbe Condita, as well as throwing in a number of other historical and (then) current examples and advice as to how to run a republic; it also includes some advice on how to run a Principality, and there is some overlap with The Prince in places. See also The Prince.
