Industrial Revolution: A period from about 1760-1840 marked by new manufacturing processes which led to rapid industrial growth, much like what was aimed for in New South.
Sharecropping: A system used on southern farms after the Civil War in which farmers worked land owned by someone else in return for a small portion of the crops. It's like renting an apartment - you live there, but the property isn't yours and you have to give something (in this case, part of your crop) to the landlord.
Jim Crow Laws: These were state and local laws enforcing racial segregation in Southern states. They're like a set of unfair rules that favor one group over another based on their race.
