#Trade is as old as society, and originated because no human collectivity is capable of producing everything it needs to live. This difficulty was what led to the commercial exchange between different peoples.
The first forms of trade between men consisted precisely in the exchange of hand-to-hand products: what one had and did not need, was changed by what the other had and did not need. That form of exchange is called barter.
