Why did the membership of the NAACP rise dramatically during World War 2?

The membership of the NAACP rose dramatically during World War II due to increased awareness of racial injustices and the need for civil rights amidst the war's fight against fascism. The war highlighted the contradictions between America's democratic ideals and its treatment of African Americans, prompting many to join the NAACP as a means to advocate for equality and civil rights. Furthermore, the migration of African Americans to urban areas for defense jobs also contributed to a surge in membership, as these individuals sought to address systemic racism and discrimination.
