Hm ok, I checked the dates to be sure and here is what I got:
3.Spanish conquest destroys Mesoamerican civilzations 1519–21
1. Pilgrims land at Plymouth November 11, 1620
2. Fighting begins at Lexington and Concord April 19, 1775
4. James Madison and others write a new plan for government April 1787
So 3, 1, 2, 4 is your answer. Feel free to ask me if you have any other questions!
