Cotton Gin
One of the primary reasons slavery continued to grow in the United States was due to the invention of the Cotton Gin. The Cotton Gin allowed the cotton to be produced and mass quantities consequently leading to mass profits. Southerners relied on slaves to use the cotton gin so slavery was expanded.
