After viewing the videos, I think revolution is the main theme. There is American Revolution, Haitian Revolution, Market Revolution and another theme is slavery whether it was of African Americans or women who considered they were treated as slaves in the factories. I believe that America has been one nation that has witnessed major revolutions that have brought about a complete change always in the nation. The American Revolution freed American colonies from the control of the British Parliament and thirteen states were established and the Article of Confederation came in to being.
