How did African Americans exercise their freedom and rights during Reconstruction?​

From my memory of APUSH, a few African Americans began working in government(very isolated cases of this), but the majority where attempting to gain their independence from previous slave owners. Many struggled under Jim Crow, and some more additionally were trapped into share cropping. Hope this helps!

Jim crow laws and riots and telling people how bad it was for them and pushing for more change

If i’m not mistaken your answer should be the freemen’s bureau started them. i really hope i could ! good luck
