Slavery is when a person is treated as the property of another person. This person is usually called a slave, with the owner being called a slavemaster. It often means that slaves are forced to work, or else they will be punished by the law (if slavery is legal in that place) or by their master.
Chains such as these were used to stop slaves from escaping
There is evidence that even before there was writing, there was slavery. There have been different types of slavery, and they have been in almost all cultures and continents. Some societies had laws about slavery, or they had an economy that was built on it. Ancient Greece and Ancient Rome had many slaves.
During the 20th century almost all countries made laws forbidding slavery. The Universal Declaration of Human Rights says that slavery is wrong. Slavery is now banned by international law. Nevertheless, there are still different forms of slavery in some countries.
The English word “slave” comes from the medieval word for the Slavic peoples of Central Europe and Eastern Europe, because these were the last ethnic group to be captured and enslaved in Central Europe. According to Adam Smith and Auguste Comte, a slave was mainly defined as a captive or prisoner of war. Slave-holders used to buy slaves at slave auctions. In many cases slaves are not allowed rights.
