The penitentiary system was literally barbaric
The penitentiary system of the age wasn’t as civilized and humane as the one today in most parts of the West. If you ended up losing your freedom, hell was waiting for you. Jails were first dungeons in castles or castle towers such as the Tower of London. A prisoner wasn’t fed and didn’t get water every day and of course there wasn’t any social activities or sunshine. Most prisoners were in irons in their cells to prevent escape attempts and many of them either died from starvation or disease.
