Transcript of Cotton Gin
What Did it Do?
How Did it Work?
-Daniel Briseno and Moo Jin Kim's Extensive Activity
born in Westboro, Massachusetts on December 8, 1765
Yale graduate who had a talent in machinery
came to South as a teacher
when his teaching job failed, his friend Katherine Green let him stay at her plantation.
Encouraged by Green, Whitney set to work on a machine which could clean seeds out of cotton bolls in a quick and easy manner. By April 1793, he had constructed the machine.
automatically pulled cottonseeds out of cotton bolls
also cleaned the fiber by removing most of debris, such as bugs and dirt
cotton bolls are inserted into the top of machine
Cotton Gin's Effect on Slavery
The cotton gin made cotton an extremely profitable crop, and as more people grew it, more slaves where needed to grow and harvest it for the cotton gin.
Between 1790 and 1850, the number of slaves in the south went from 500,000 to more than 3 million.
By 1860, ~1/3 southerners was a slave.
Without the cotton gin, slavery might have died out on it's own as it was beginning to decline.
The Cotton Gin's Efficiency
•Before the invention, laborers spent hundreds of dreadful hours to separate cottonseed from the raw cotton fibers
•The cotton gin automated the seed separation; it could clean as much cotton in one hour as a slave can clean by hand in one day.
Europeans were unwilling to pay high prices for tobacco and rice offered by U.S. They could get the crops much more cheaply from other British colonies.
Cotton was a promising crop, but before the cotton gin, it had little value.
i will be going to mexico tomorrow, i am not sure if prezi works down there, or if I'll have time to work, but i'll try to get more done, i'll definatly do at least 2 more slides from now to monday, at least i'll try.
Cotton Gin's Effect on Southern Economy
The cotton gin created a huge expansion of cotton production in the U.S, primarily in the south.
Cotton production went from 750,000 bales in 1830 to 2.85 million bales in 1850.
As a result, the southern economy became even more dependent on slave labor and plantation system.
By 1860, the southern states were providing about 2/3 of the world's supply of cotton and up to 80% of the crucial British market.
