The economy in the 19th century is very different from our economy now. The Northern and the Southern economies had very different ways of making profits. The North was based on manufacturing. This was because the climate and the soil in the north did not encourage large plantations, but more so small farms instead. The North could not rely on only agriculture to promote their economy so they had to find another solution which was manufacturing. In the early 1800’s Irish immigrants were forced to immigrate to America after the potato blight. They had to start new lives and find new jobs in order to survive in their new home. This is why many factories in the North had immigrant employees. After the spark of the cotton gin factories in North started to produce cloth. The south was small and mainly existed to meet the needs of a farming society. It had a very agricultural economy that relied mainly on slavery and cash crops. Slaves played major roles in the economy when it came to the production of cash crops such as tobacco, rice, and sugarcane. Slaves worked on the fields and tended to the needs of the many cash crops in order for the plantation owner, or the slave masters, to trade and sell the plants. The most important cash crop in the south was cotton because it was the most profitable and the most valuable cash crop. Anyone who handled the crop became extremely wealthy, except for the slaves of course. Since cotton was so profitable plantation owners ordered for more and more of it to be grown which lead to the cotton gin. The cotton gin lead to a spark in slavery, so more plantation owners were buying and selling slaves, and expanding their lands.
