One major reason slavery did not flourish in the North was due to the region's economy being focused on industry and commerce rather than agriculture. The Northern economy did not rely on large plantations and cheap labor, as the South did. Additionally, the harsh winters and rocky soil in the North were not ideal for the agricultural practices that were prevalent in the South. This made it less desirable and less profitable for slave owners to maintain large plantations in the North, leading to a lower demand for slave labor.
