Think, what was the main difference between a slave and a free man?

With the development of human society, relations between people have also changed. So, with the advent of economic inequality, social inequality arose, that is, richer and noble people appeared. Over time, this inequality became deeper, some people began to depend on others, first economically and then personally. So, the concept of slavery appeared. A slave was a commodity, a thing that could be sold, exchanged, bought. A free man was distinguished by personal freedoms and could make decisions himself. This situation persisted for a very long time.
