The Fugitive Slave Acts  OF 1850, was a  federal law that allowed for the capture of runaway slaves and thier  return within the territory of the United States which authorized  local governments to seize and return escaping slaves  to their owners and penalized  anyone who aided their escape.

--- The Northern states provided a safe haven for runaway slaves and were termed  free states, The Southern Politicians were concerned with the development from the Northern states and then introduced a Constitution---Fugitive Slave Clause to force the states to enforce slavery in which no person held to service  can be released if they escaped to a free state.
