Final answer:
Booker T. Washington wrote 'Up From Slavery' to showcase the industry and integrity of African Americans and promote racial harmony.
Step-by-step explanation:
Booker T. Washington wrote 'Up From Slavery' to showcase the industry and integrity of all African Americans, rather than to demonize his former owners or celebrate his personal accomplishments. He wanted to emphasize racial harmony and honor in his narrative, providing examples of both the horrors of slavery and the potential for positive race relations. Washington's purpose was to encourage the industrial and moral uplift of African Americans and promote the idea of self-improvement within the constraints of segregationist laws.
