What are the 3-5 most important historical events for understanding the modern day US?

by Yamster80

Understanding why the modern day is the way it is - politically, culturally, etc. And cultural references. And if you can explain why too, that would be awesome.

Sorry, we don't allow "example seeking" questions. It's not that your question was bad; it's that these kinds of questions tend to produce threads that are collections of disjointed, partial, inadequate responses. If you have a question about a specific historical event, period, or person, feel free to rewrite your question and submit it again. If you don't want to rewrite it, you might try submitting it to /r/history, /r/askhistory, or /r/tellmeafact.

For further explanation of the rule, feel free to consult this META thread.
