As a diplomat in turbulent fifteenth-century Florence, Niccolo Machiavelli (1469-1527) knew how quickly political fortunes could rise and fall. "The Prince" is his controversial handbook about the dynamics of power, leadership and strategy. Machiavelli's shrewd argument that sometimes it is necessary to abandon ethics to succeed made his name notorious. Consequently, "The Prince" has been read by strategists, politicians and business people ever since.
