In ancient times, communities would often rid themselves of convicted criminals and other undesirables through the practice of banishment: casting unwanted people out into the wilderness. The Romans often employed banishment as an alternative to capital punishment, and indeed, considered it a fate nearly as terrible as death. Later, the British Empire liberally employed the punishment of banishment and transportation to colonies such as Australia, while the Soviet Union became known for its use of internal banishment to Siberia. The terms exile, outlaw and outcast all owe their origin to this once widespread practice.
As the world grew smaller, banishment, as a practical matter, virtually ceased to exist. Though it still remains on the books in a few Southern states, it is generally thought of as an archaic form of punishment, and one that cannot function effectively in the modern world.
Yet the impetus behind banishment — to permanently remove individuals from society, and subject them to a kind of “social death” — flourishes today in the American criminal justice system, where prisons and jails are the settings for a new kind of internal exile.
