Final answer:
The NACWC improved the lives of African Americans by addressing community needs and fighting segregation, led by influential leaders such as Ida B. Wells-Barnett and through providing critical social services.
Step-by-step explanation:
The National Association of Colored Women's Clubs (NACWC) played a pivotal role in improving the lives of African Americans by focusing on community uplift and tackling the pervasive issue of segregation. By promoting the coordination of local African American women's clubs, they provided a unified front against racial injustices. Initiatives led by powerful figures such as Ida B. Wells-Barnett, who launched an anti-lynching campaign, and other leaders like Josephine St. Pierre Ruffin and Mary Church Terrell, worked tirelessly for women's rights and for ending lynchings. They also established significant social services, including orphanages and homes for the elderly. Although they sometimes faced confrontation from other suffrage organizations like the National American Woman Suffrage Association (NAWSA), they persisted in their advocacy, highlighting the resolute spirit of these women in the face of discrimination.
