Which Italian Renaissance figure is best known as a political philosopher?

Niccolò Machiavelli is recognized as a significant political philosopher of the Italian Renaissance primarily for his work "The Prince." In this influential text, he explores the nature of political power and the qualities that a ruler must possess to maintain authority and navigate the complexities of governance. Machiavelli's ideas, such as the concept of realpolitik and the separation of ethics from politics, have significantly impacted political theory and practice. His pragmatic approach to leadership, emphasizing effectiveness over ideals, has established him as a cornerstone figure in political philosophy.

The other figures mentioned made remarkable contributions in various fields, such as art and literature, but did not focus primarily on political philosophy. Leonardo da Vinci is renowned for his artistry and scientific innovations, while Michelangelo is celebrated for his sculptures and paintings. Thomas More, though a political figure and philosopher, is more closely associated with his work "Utopia," which explores social and political ideals rather than the practicalities of ruling that Machiavelli addresses in his writings.
