What is the name of the labor system that developed throughout the South after the Civil War kept poor blacks and white working in agriculture'?

The labor system that developed in the South after the Civil War is known as sharecropping. This system allowed poor black and white farmers to work land owned by others in exchange for a share of the crops produced. While it provided a means of subsistence, sharecropping often trapped families in a cycle of debt and poverty, perpetuating economic inequality in the region.
