Answer:
Ever since the formation of the United States of America, the North and the South followed different paths. By the mid 1800s, the differences between the two regions were so pronounced that many observers felt like the country was home to two distinct cultures.
The North was becoming more and more industrial and dedicated to free labor and immigration. Many Northerners committed themselves to chasing the American dream of the poor man working hard, making a home for himself, and perhaps even doing great things. Slavery was not common and even banned in some states, and a growing abolitionist movement frequently demanded freedom for all people. The North was also more inclined to support a strong federal government.
