Why did Franklin d Roosevelt agree to desegregate the defense industry?

Franklin D. Roosevelt agreed to desegregate the defense industry primarily to address the growing pressure from civil rights activists and organizations, such as the NAACP, who advocated for equal employment opportunities during World War II. Additionally, Roosevelt recognized the need for a unified workforce to maximize production efforts for the war, which required tapping into the skills of all Americans, regardless of race. By desegregating the defense industry, he aimed to alleviate labor shortages and promote social justice, aligning economic necessity with moral imperatives.
