Hey there!
For one thing, it sure was rebellious.
In this time, the people of the United States (however, that's not what it was called, rather the 13 colonies- we hadn't obtained most of our territory yet) were under the rule of King George II of Great Britain, and he didn't exactly treat the colonists with utmost respect.
Therefore, the colonists rebelled a lot and that eventually led to their
freedom.
Hope this helped!
