The Cotton Gin
The First invention of industrialized agriculture!
Reason for Invention
The cotton gin was invented to separate the cotton seeds from their fibers. This was first done by manual labor, which took a lot of time. The cotton gin replaced the need for manual labor, but dramatically increased the need for slaves. Advanced versions of the cotton gin are still in use today for clothe production.
The cotton gin dramatically sped up the harvest of cotton, but more historically, it hugely increased the need for slavery in the south in an increasingly abolitionist nation.
