The Freedmen's Bureau had the most succes for African- Americans by helping their in securing educational opportunities during the reconstruction period. They construscted more than a thousand schools for the newly freed African- Americans and invested $4000 for the teacher-training institutions. They also provided practical aid for their transistion from slavery to freedom.
