Industrial Revolution Period in history in which technological advances led to mass economic changes. Began in Britain Machines replace manual labor

Eli Whitney Whitney was one of the early founders of the "American system" of mass production Identical parts were produced by machines, and then assembled by hand Whitney popularized the machine which produced interchangeable parts for guns

Eli Whitney Invented the Cotton Gin as a means of easily separating the seeds from the cotton The Gin was mass produced using interchangeable parts Increased the amount of cotton that the South produced, increasing the demand for slaves

Why were Eli Whitney’s ideas so Important? The cotton gin reduced the cost of producing cotton and greatly raised the profit from growing it. Interchangeable parts made it possible for people to keep their items (i.e. musket) after the item was fixed, instead of having to throw it away because it would never work again. Semi-skilled or unskilled workers could work in factories to produce these items, instead of needing a skilled laborer.
