After the war, how many slaves were free in maryland? a. no slaves b. about 1⁄3 of the population c. about 3⁄4 of the population d. all slaves

D. All slaves

Explanation:

Maryland really nullified subjugation while the war was all the while being battled, on 1 November 1864. This was after a political campaign to change the state's constitution to make slavery illicit, which was passed (by an exceptionally thin edge) after a referendum.  

There had been 87,189 slaves in Maryland before the war, as indicated by the 1860 statistics. A considerable lot of those slaves accomplished their own opportunity during the war a very long time by fleeing, and a significant number of them joined the Union Army. The individuals who stayed in servitude were liberated in November 1864, five months before the war finished.
