Why did sharecropping and share tenancy develop

After the end of the Civil War, two new forms of agricultural labor filled the vacuum of slavery. these two forms of agriculture are of course sharcropping and tenancy. Sharecropping emerged from the conflicting interests of former slaves and former slave plantation owners. for planters, it was a way to resume agricultural production, as large plantations were turned into individual family plots. for slaves, it moved away from the gang labor system and freed them from the constant supervision of white overseers. tenant farmers were mostly white and they developed tenant farming so they could keep their crops and sell them to people.
