Slaves rebellions were always a possibility. But that's to be expected when people are treated as property, and slaveowners were right to be scared of a slave rebellion.
As noted in another thread:
"Of course, Federal assistance and requirements to return fugitive slaves ramped up even more slaves being given assistance to go to Canada, being hidden, and some states making return of fugitive skates as time consuming as possible.
That’s not to say that slaves should not have tried to escape, or rebel, or States should not have fought the return of fugitive slaves. Those did occur, were encouraged and should have been."
“But that’s to be expected when people are treated as property, and slaveowners were right to be scared of a slave rebellion.”
I’ve often wondered about that. If slavery was as horrible as we’ve been led to believe, why wasn’t there massive, overwhelming rebellion? Hmmm?
