Machiavelli's theme in this chapter is the relationship between the people (the ordinary citizens) and their opposites, the nobles (the upper classes from aristocratic families). Machiavelli portrays these two groups as constantly at odds, but his sympathy is clearly with the people, who only want to live free under the rule of their own laws. Machiavelli himself belonged firmly in this group, having been prevented from holding high office because he was not an aristocrat, and having served his entire career in Florence's civil government. The Medici, to whom he was writing, were members of the nobility, and this makes his advice somewhat more daring than it may sound at first. As in Chapter 5, Machiavelli can be seen reminding the Medici how much free states like Florence value their freedom and how justified they are in doing so.
Machiavelli emphasizes how necessary it is for a prince to win over the people, because they are many, while the nobles are few, and a prince can never live safely without being able to trust the people. On this subject, Machiavelli was going against prevailing opinion, which he acknowledges by quoting the proverb "He who builds on the people builds on mud." In fact, he is able to find only one example to support his argument (Nabis the Spartan), but two that disprove it (the Gracchi and Messer Scali). Machiavelli had many opportunities to observe the fickleness of the Florentine people, as they had alternately supported the Medici, Savonarola, the Republic, and then the Medici again.
