When Machiavelli wrote The Prince in 1513, he faced a lot of criticism. What were the key ideas of The Prince, and how did these ideas influence European rulers?

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.
