What American city popularized the term black?

The American city that popularized the term "Black" in reference to African Americans is Detroit. In the late 1960s, during the Civil Rights Movement, Detroit became a central hub for discussions about race and identity, particularly following the Detroit riots in 1967. Activists and community leaders in the city used the term to foster a sense of pride and solidarity among African Americans. This movement contributed to the broader acceptance of "Black" as a positive identifier within the community.
