Machiavelli was the most famous political theorist of this era. He was the secretary to the government in Florence, but was later arrested for plotting against the Medicis. He later wrote for the rest of his life. The Prince, his most famous work, uses examples of rulers to make the point that the purpose of a government is to maintain order and security. Machiavelli believed that a weak leader led to disorder, and the possible downfall of a society. Rulers, he said, should maintain power by whatever means possible. The Prince is considered one of the first guides to politics, and Machiavelli is viewed as a ruthless thinker.
