What were some of the new social opportunities for african americans in the south after the civil war, and how were african americans prevent from taking full advantage of these opportunities?

After slavery finally came to an end the government across the South created black codes. These laws gave certain legal rights to blacks, they were finally given the right to marry, own property, and sue in court, but the Codes  made it illegal for blacks to serve on juries, go against whites. The black codes basically made everything harder for African Americans.

they remained in rural areas and worked at jobs such as lumbering or farming.

the tariff was created to protect industry in the northern part of the united states. industries in the north were being driven out of business by imported goods that were priced at a low rate. the goal was to protect these industries   by taxing the goods.
