The Prince
"The Prince" is a political treatise by Machiavelli that is not considered to be representative of the work published during his lifetime, but is the most remembered. The theories in this book describe methods that an aspiring prince can use to acquire the throne, or an existing prince can use to maintain his reign. These theories include defense and military, perceived reputation, generosity, cruelty versus mercy, gaining honors, fortune and a number of other discourses.
