Various mental influences were at work during its composition; its title and patron were changed; and for some unknown reason it was finally dedicated to Lorenzo de' Medici.

Although Machiavelli discussed with Casavecchio whether it should be sent or presented in person to the patron, there is no evidence that Lorenzo ever received or even read it: he certainly never gave Machiavelli any employment.

Although it was plagiarized during Machiavelli's lifetime, "The Prince" was never published by him, and its text is still disputable.
Machiavelli concludes his letter to Vettori thus: "And as to this little thing [his book], when it has been read it will be seen that during the fifteen years I have given to the study of statecraft I have neither slept nor idled; and men ought ever to desire to be served by one who has reaped experience at the expense of others.

And of my loyalty none could doubt, because having always kept faith I could not now learn how to break it; for he who has been faithful and honest, as I have, cannot change his nature; and my poverty is a witness to my honesty." Before Machiavelli had got "The Prince" off his hands he commenced his "Discourse on the First Decade of Titus Livius," which should be read concurrently with "The Prince." These and several minor works occupied him until the year 1518, when he accepted a small commission to look after the affairs of some Florentine merchants at Genoa.

In 1519 the Medicean rulers of Florence granted a few political concessions to her citizens, and Machiavelli with others was consulted upon a new constitution under which the Great Council was to be restored; but on one pretext or another it was not promulgated.
In 1520 the Florentine merchants again had recourse to Machiavelli to settle their difficulties with Lucca, but this year was chiefly remarkable for his re-entry into Florentine literary society, where he was much sought after, and also for the production of his "Art of War." It was in the same year that he received a commission at the instance of Cardinal de' Medici to write the "History of Florence," a task which occupied him until 1525.
