Niccolo Machiavelli (1469-1527) was born in Florence, and served the Florentine republic as a secretary and second chancellor, as ambassador and foreign policy-maker. When the Medici family returned to power in 1512 he was suspected of conspiracy, imprisoned and tortured and forced to retire from public life. His most famous work, The Prince, was written in an attempt to gain favour with the Medicis and return to politics.
