Florentine political theorist, author of The Republic (11)
I believe the answer is:
machiavelli
(Other definitions for machiavelli that I've seen before include "Italian political philosopher, proponent of unscrupulous government, d. 1527" , "Italian political philosopher, author of "The Prince"" , "Author of The_Prince" , "Statesman of Florence" , "unprincipled politician" .)
