One important aspect is the struggle for independence. The colonists were tired of being under British rule and fought for their own nation. Another is the role of immigration. People from all over the world have come to the US, adding to its cultural richness. Also, the westward expansion was crucial, as it increased the size and resources of the country.
The 'US back story' is complex. It began with the arrival of European settlers. They came seeking new opportunities, religious freedom in many cases. The colonies grew over time, and there were various interactions with Native Americans, some friendly, but unfortunately many were not. Eventually, the colonies united to fight for independence from Britain, which led to the birth of the United States as we know it today.

I don't think so. It could be inspired by various elements but not a direct retelling of a true story. Fictional stories often combine different ideas and concepts to create an engaging narrative.
