In Chapter 1, Machiavelli traces the basic outlines of a discussion that will take him through Chapter 11: the different types of states, how to acquire them, and the difficulties they present to a ruler. Machiavelli refers to republics, which are governed by their citizens, and principalities or princely states, which are governed by a single, strong ruler (a prince). Because he is addressing one of those princes, he avoids any discussion of republican government, except to note that republics conquered by a new prince are used to living free, a theme he returns to in later chapters. In many of his other works, Machiavelli passionately defended republican forms of government, and he suffered for his defense of the Florentine republic which the Medici now ruled.
Hereditary principalities are those in which rule is passed down among members of one family. Machiavelli considers these the easiest to govern and therefore disposes of the subject by observing that any minimally competent prince can hold onto one. At the end of Chapter 2, Machiavelli makes the first of his many observations about human nature, noting that people are inclined to forget that even old established governments were innovations once.
