Final answer:
In 1946, the National Negro Congress (NNC) was an active participant in the civil rights movement, expressing the Negro nationalism that celebrated African American heritage and fought against racial injustices and discrimination.
Step-by-step explanation:
In 1946, the National Negro Congress (NNC) continued to reflect and express the ideas and goals of what could be termed Negro nationalism. This ideology, inspired by leaders like W. E. B. Du Bois, emphasized African Americans' distinct national heritage, a sense of pride, community, and the promotion of Black literature and cultural expression. The NNC, a part of the larger civil rights movement, was actively involved in fighting against racial injustices and systematic segregation alongside other groups like the National Association for the Advancement of Colored People (NAACP) and the National Urban League (NUL).
During World War II and its aftermath, including 1946, these organizations, including the NNC, pressed for progress in civil rights, employment equality, and an end to discrimination. In particular, the efforts and outcomes such as the March on Washington Movement, Executive Order 8802, and the establishment of the Fair Employment Practice Committee (FEPC) were significant achievements inspired by the persistent advocacy of these groups.
