<span>Black codes were restrictive laws designed to limit the freedom of African Americans and ensure their availability as a cheap labor force after slavery was abolished during the Civil War. Though the Union victory had given some 4 million slaves their freedom, the question of freed blacks’ status in the postwar South was still very much unresolved. Under black codes, many states required blacks to sign yearly labor contracts; if they refused, they risked being arrested, fined and forced into unpaid labor. Outrage over black codes helped undermine support for President Andrew Johnson and the Republican Party.</span>

Answer:
Jobs in the city
Explanation:
The majority of the people that had given up on farming and moved to the cities is because of the jobs that the cities have offered. Most of the people did not had large farmlands, but instead they either had small ones, or were working for the large land owners. In this kind of circumstances they were earning very low amounts of money, so in general they were poor or on the verge of being poor. Since the cities were developing quickly, the industry was growing, and there was a constant demand for labor force, most of the people left the farmlands in order to get a job into the cities, so that they can have a better life.
