Why did the plantation system of agriculture developed in the southern united states instead of the north eastern united states?

Because in the southern states they had slaves to take care of their farms unlike the northern states.

South carolina was so angry about the election of lincoln that they seceded from the union on december 20, 1860. they attacked fort sumter later, on april 12, 1861.
