One of the clearest divisions in the country manifested itself early as a diversion of interests between whom?

In the 1840s and 1850s there was a rising division as regards cultural and intellectual terms between the North and the South of the country. Between 1854 and 1861 a small civil war took part in Kansas. It was known as Bleeding Kansas and it was a series of violent civil confrontations between the ones who were in favour of the legality of slavery and the ones who were against it.
