Roman Slavery
Other slaves were forced to work deep underground in the mines, getting gold or silver or copper or iron or tin for the Roman government. They also suffered and died after just a few years. The Roman government, and private traders, owned many men who rowed ships as slaves, often chained to their oars. Many of these men were sentenced to the mines or to the ships because they were criminals. We don't use men to power ships anymore, and we don't send criminals to the mines, but miners still have difficult and very dangerous work.
