From The Hill:

One month after the Confederate surrender in 1865, Frederick Douglass urged federal action to stop state and local infringement of the right to arms. Until this was accomplished, Douglass argued, “the work of the abolitionists is not finished.”

Kansas Senator Samuel Pomeroy extolled the three “indispensable” “safeguards of liberty under our form of government,” the sanctity of the home, the right to vote, and “the right to bear arms.” So “if the cabin door of the freedman is broken open and the intruder enter…then should a well-loaded musket be in the hand of the occupant to send the polluted wretch to another world.”
