The Cotton Gin and the Expansion of Slavery
In Grade 8 US history, students learn how Eli Whitney invention of the cotton gin in 1793 transformed cotton farming and dramatically expanded slavery. Before the cotton gin, separating cotton fibers from seeds was slow and made slavery less profitable. The machine made processing cotton 50 times faster, creating enormous demand for enslaved labor across the South. This topic is covered in History Alive! The United States Through Industrialism, Chapter 6.
Key Concepts
In the late 1700s, demand for cotton was high, but separating its fibers from the seeds was a slow, difficult process. Because of this, using enslaved labor to produce cotton was not always profitable.
This changed in 1793 with Eli Whitney’s invention of the cotton gin . This machine cleaned cotton far more quickly than a person could by hand, making it much easier to prepare for the market.
