The Declaration of Independence/The Marriage of Figaro

 Thomas Jefferson is part of the Enlightenment era. In The Declaration of Independence he states "A Prince whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people." He believes that people are free beings who be able to separate from the Monarch in England. He said all men are created equal and every one has God given rights that no one can take away. A Monarch would set laws as he sees fit and everyone had to follow. . .or else. A free man should be able to choose who he wants as leader.
The Declaration of Independence and The Marriage of Figaro both revolve around a Monarch who is sneaky and conniving, and will go to the extremes of getting what they want. Jefferson and Mozart wrote about a free man who can vote for law, who can have privacy in his marriage, and has a leader who knows what is best for the people. Jefferson writes of a Monarch who still rules land over sea and uses to make extra money by taxes and quartering soldiers. Mozart writes of a selfish Count who likes to have private meetings with other ladies. Both rulers are making arrangements that suit there wants and needs.
