There are fewer difficulties in holding hereditary states, and those long accustomed to the family of their prince, than new ones; for it is sufficient only not to transgress the customs of his ancestors, and to deal prudently with circumstances as they arise, for a prince of average powers to maintain himself in his state, unless he be deprived of it by some extraordinary and excessive force; and if he should be so deprived of it, whenever anything sinister happens to the usurper, he will regain it.
