1) The Constitution - The convention was formed, and the constitution enacted by basically going around the prior Government based on the Articles of Confederation. Fixed lots of things, changed us from a Confederation to a Republic. Movement started at a trade/commerce convention in Annapolis which didn't work out. Constitution was signed by 39 of the 70 delegates appointed to the Convention, with like 53 or 55 actually showing up. Main concerns were getting a Government that would pay off some bad bond investments, fix some bad land investments and generally be really good for people interested in trade/commerce. We the People = We the Lords of Commerce in these Colonies ;)
2) The Civil War - basically the Rebels lost, so ...
3) The Reconstruction - Lincoln essentially lets the slave states back into the Union but gets assassinated. The Republicans had nominated a Democrat(!) - a southerner(!) from N.C. and Tennessee - Andrew Johnson as Vice President. He begins reconstruction. Congress, including the Southern states, passes the 13th amendment in 1865 abolishing slavery. But the Southern states are making "Black Code" laws and basically making life hell for the freed slaves.
The "Radical Republicans" control congress and basically impose martial law on the South and kick the southerners out of congress. Johnson fights them all the way seeing as how depriving states of representation is unconstitutional among other tactics. But they get enough majority to override his veto's. They brought 11 different impeachment counts against him and one of those failed by a single vote.
They let the Southern states back in basically contingent on they're ratifying the 14th amendment. Some claim it's never been fully ratified. This requires due process, lets the feds override states on issues concerning citizens rights, and forgives Union debts while upholding Confederate debts. It's revolution because they break the constitution in order to pass the amendment and the amendment basically moves a bunch of power from the individual states to the Federal government.
4) Revolution or Coup? The Aldrich group expedition to Jekyll Island, 1910
America had fought hard to avoid a central bank, and had pinned banking scares in 1873, 1893 and 1907 on International Bankers in London. So Congress formed the National Monetary Commission to come up with a plan to prevent banking scares in the future and keep the International Bankers and wall-street types away from control of the nations money and credit. The commission evidently took a 2-year holiday in Europe and then a Cartel of nameless banking barons snuck off to Jeykl Island and devised the whole plan in super-secret, in 9 days. They didn't use names so that even the participants would not know who exactly had participated. They came up with the "Aldrich Plan". They eventually got it pushed through as the "Federal Reserve Bank" and sold the country to 8 International bankers AND gave them the right to create money and make it a U.S. Government obligation.
A good read and lecture on it here -
