In slavery, the slave owners own the system of slaves.The work force must be dominated by slaves, without remuneration, and without personal freedom.In a human society, if most of the workers in the field of material production are slaves, such a society is called a slave society.

In addition, ancient Greece, ancient Egypt, Babylon, pre-war China, the South of the United States before the war, and some former colonies of Britain, France, and Russia were subject to slavery.
