Answer:
The new labour system established in the south during reconstruction was sharecropping.
Step-by-step explanation:
The new system introduced in the south was sharecropping. Under this system the black families would work on a small piece of land, they would live and grow crops on it.
As rent the families would give a portion of their crops to the landowners. It helped them lived safely and had a secure source of income. Sharecropping was mostly done in the south.
