How did the US assert itself as an independent nation?

The United States asserted itself as an independent nation primarily through the Declaration of Independence in 1776, which articulated its desire for self-governance and separation from British rule. This assertion was further solidified by winning the Revolutionary War (1775-1783), culminating in the Treaty of Paris in 1783, which recognized American sovereignty. Additionally, the establishment of a Constitution in 1787 provided a framework for governance that emphasized democratic principles and individual rights, reinforcing its status as an independent nation.
