To be honest, I dont know. I'm actually not an American. :)
But If i had to pick one major event...it would be making George Washington the president.
To explane.
George Washington's presidentsy in a way made America, in some aspects, what it is today.
Now imagine if he was not made a president but chose to be a dictator. I know its funny and my nest statement is going to be even funnier.
Assassins Creed 3: The rule of King George did a decadent job in imagining and explaning this. I recommend reading its plot, I think you would find it interesting. Its full of what ifs and alternative history events.
Sorry for not giving my version but its a bit hard for me to imagine something like that.
If I wanted to get a better salary, my boss and I would have to bargain to figure out what is fair. A big example with this is in factories with working conditions. For example, wanting a certain amount of break time, or having drinks included with their work, etc. I don't know what they examples are, but this definition should help you out. If it doesn't, just comment what the examples are and I'll help figure out which one it is.
The declaration of independence had reflected the social

and rights to every person.
An example of a theory is Evolution, we don't really know 100% how we came to be as we are now, but we do know that 1+1=2 as a fact, same with gravity, we Know it exists because it's what ties us to earth and we can "feel" it, but not Evolution, Evolution is a theory, just like the BingBang
