Explain why the Fugitive Slave Law was so unpopular in the North and why Uncle Tom’s Cabin, was so popular there.

What will be an ideal response?

ANSWER
The Fugitive Slave Law compelled northerners to abandon their general indifference to the South’s “peculiar institution,” and directly involved them in some of the more sordid aspects of capturing runaways and returning them to slavery. Also, enforcement of the law violated their sensibilities of civil liberties. Uncle Tom’s Cabin portrayed slaves as sympathetic characters trapped in an atrocious slave system. Its popularity was closely tied to its timing–during the northern outrage over the Fugitive Slave Law.
