The most accurate response regarding the impact of American independence on African Americans is:
It failed to give African American rights or protections.
While the American Revolution espoused ideals of liberty and equality, these principles were not extended to African Americans, particularly those who were enslaved. The independence of the United States did not lead to immediate freedom for all enslaved people, nor did it guarantee the same rights as white men for free African Americans. Although some free African Americans did gain opportunities to serve in government and engage in civic life, the broader system of racial inequality and discrimination persisted following independence.
