There was an attempt by some well known bankers, J.P. Morgan being one of them, who attempted a coup d'etat against President Franklin D. Roosevelt. See "Business Plot" on wikipedia.

Presidents George H.W. Bush and George W Bush's father, Prescott Bush, was involved with helping to finance Nazi Germany during the WWII. See "How Bush's grandfather helped Hitler's rise to power".

Other things I find interesting in our history are:

George H.W. Bush may have been involved in the Kennedy Assassination and How Richard Nixon was quite close to the Bush family. See "JFK II: The Bush Connection" and "Dark Legacy" on Netflix.

Some other interesting history about George H.W. Bush is a film titled, "The Panama Deception" on Netflix.

All the "Loose Change" videos regarding the 911 incident are quite interesting.

Also two books are quite interesting that tell another side of American history and how big money and power perpetrate many evils, "The Creature From Jekyll Island: A Second Look At The Federal Reserve" and "Confessions of an Economic Hit Man". The former tells how big money likes war and makes alot of money from it. It tell how we were brought into WWI through the Lusitania incident. The latter tells a story of how economic hit men are sent to underdeveloped countries to try and get them to borrow big money and make them heavily indepted to the banks. If they don't cooperate, then jackels are sent in to assassinate their leaders or create a coup. It that doesn't succeed, then we go to war.

Finally, if you can get past their anti-religion/anti-christian B.S., the Zeitgeist movies on Netflix are informative about some events in history as well as what is wrong with our current state of affairs. According one of the films, FDR helped to get us into WWII.
