  1. 1. Technological Innovation: The Cotton Gin By: Amy Gregory
  2. 2. Before the Cotton Gin <ul><li>Small cotton economy existed in the South near the coasts of South Carolina and Georgia </li></ul><ul><li>Could only use the long-staple cotton because it was easier to separate from its seeds </li></ul><ul><li>The main source of economy in the southern states were indigo and tobacco </li></ul><ul><li>Cotton had to be picked, and de-seeded by hand before it could be sold, mainly by slaves </li></ul>
  3. 3. History of the Cotton Gin <ul><li>Created by Eli Whitney in 1973 </li></ul><ul><li>-Eli made very little money off the invention </li></ul><ul><li>- Farmers would duplicate the cotton gin without royalties </li></ul><ul><li>The machine had a very basic idea </li></ul><ul><li>-Cotton bolls were put into the top of the machine  </li></ul><ul><li>- Next, you turn the handle, which turns the cotton </li></ul><ul><li>through the wire teeth that combs out the seeds  </li></ul><ul><li>- Then the cotton is pulled out of the wire teeth and out of the cotton gin </li></ul><ul><li>Could produce up to fifty five pounds of cleaned cotton daily, making it very popular and profitable in all areas of the South </li></ul>

  5. 5. Negative Effects of the Cotton Gin <ul><li>The need for slaves increased dramatically in the U.S, from around 690,000 in 1790 to around 3.95 million in 1860 as the production of cotton increased </li></ul><ul><li>The following link shows the increase of slavery from 1790-1860 </li></ul><ul><li>http://mappinghistory.uoregon.edu/english/US/US18-02.html </li></ul><ul><li>Was a factor in the Civil War between the North and South because plantation owners were dependent on slaves to pick their cotton from the fields, this lead to hostility towards the Northern states in their attempt to regulate slavery </li></ul><ul><li>Depleted soil nutrients, making parts of the South less fertile over time </li></ul>
  6. 6. Positive Effects of the Cotton Gin <ul><li>Made producing cotton fast, which made the yield of raw cotton double each decade after 1800 </li></ul><ul><li>Northern part of the U.S. bought more cotton and built more textile mills </li></ul><ul><li>Cotton became America’s leading crop, known as the “King” </li></ul><ul><li>At midcentury the South provided three-fifths of America's exports, most of it being cotton </li></ul><ul><li>Played a huge role in the Industrial Revolution </li></ul><ul><li>- Encouraged the demand for cotton mills, which created the demand for more workers </li></ul>
