What is the connection of American slavery to prejudices against African-descended peoples? Why does race persist after abolition?

in 1862, president lincoln's emancipation proclamation opened the door for african americans to enlist in the union army. although many had wanted to join the war effort earlier, they were prohibited from enlisting by a federal law dating back to 1792.

explanation:

general allotment act (dawes act) february 8, 1887

amendment to the dawes act, february 28, 1891

commission to the five civilized tribes (dawes commission), march 3, 1893

if it were me, i would pick c. c is the best answer because it's basically saying go on a non-violent strike for india

what's the passage bud?
