So 3 history questions. I am asking them here cuz no one in the history section answers -_-
Question 1: How come on maps was New York not dated for when it became a state?
Question 2: What was the status of Virginia in 1819?
Question 3: If the United States had not followed the idea of manifest destiny, would its national security have been compromised?
Don't have to answer them all, but please help because I already answered 20 and I just don't know these. Thank you.
