Explanation:

The great Compromise of 1850, between the states of the North and those of the South, was the only way that it was possible to finally reach an end to miliary confrontation and the idea of retiring from the Union, after the Civil War. However, despite the fact that this Compromise was reached through a lot of negotiations between the two sides, there were several points on which both did not agree, and in the end, these oppositions made the whole pact fail. But none of the points against the Compromise was ever more potent in bringing the whole thing down, than the infamous Fugitive Slave Law, under which, the North agreed to return all escaped slaves to their former owners in the South. This was something the North did not agree to really, and in the end they never enforced it.
