During the 19th century, Southern cotton was in high demand. This was a consequence of the new technological developments which allowed cotton to be produced much faster, making it much cheaper. This also led to the growth of plantations and slaves, as a large labour force was needed in order to address this demand. As the textile industries developed in the North, the South also benefited, as this increased demand for their cotton.
It caused millions of Americans to die of starvation.
