Commerce relates to “the exchange of goods and services, especially on a large scale”.  It includes legal, economic, political, social, cultural and technological systems that operate in a country or in international trade.

Some commentators trace the origins of commerce to the very start of transactions in prehistoric times. Apart from traditional self-sufficiencytradingbecame a principal facility of prehistoric people, who bartered what they had for goods and services from each other (the barter system was popular in ancient times where one could get goods and services by offering the other person some other good and service according to their need instead of paying with monetary systems, which developed later). Historian Peter Watson and Ramesh Manickam date the history of long-distance commerce from circa 150,000 years ago.
