How machiavelli arranges the plot of the prince

The Prince begins with an address to Lorenzo de Medici, in which Machiavelli explains that he is seeking favor with the prince by offering him some of his knowledge. He then proceeds to classify the various kinds of states: republics, hereditary princedoms, brand-new princedoms, and mixed principalities. New states are his primary focus, for those are the hardest to deal with. A conquered state whose original prince was its sole ruler is difficult to conquer, but easy to maintain; a conquered state in which the prince shared power with the barons is easy to conquer, but difficult to maintain.
