What political problems did newly freed slaves face

Many freed slaves remained on their plantations and worked as sharecroppers. In this arrangement landowners (former plantation owners) also had no money to hire workers so what they would do is allow a freed slave to work the land and give a portion of the harvest to the landowner. The portion was usually quite high and it was difficult for the freeman to save enough to to sell on his own. In theory a sharecropper could save enough money to buy some mules and eventually rent the land but this was rare.
