Answer:
The main idea of the The Prince can be summarized in the phrase "the end justifies the means".
Explanation:
in his book, Machiavelli writes a series of analysis and advice to monarchs (or princes, hence the name of the book) on political matters. Machiavelli advices the princes to act wisely, but also ruthlessly when needed, acknowledging that the main goal of politics is the retention of power, and survival.
The book influenced many politicians of the time, especially in Machiavelli's native Italy. It is thought to have contributed to the dramatic political environment, including that of Renaissance Florence, where the famous Medici Family were the main characters.
