The First Nations have been trading among themselves for hundreds of years. The trading parties had corn, tobacco, furs, copper, pottery, and many other goods. They traveled long distances to trade with their neighbors. They traded to get what the needed.
Before the trade started, those who traveled long distances would rest. Then they would establish trust, feelings and respect with their hosts by exchanging gifts and sharing the peace pipe. Wampum would be offered to honor friends and create harmony.
When the French came, they learned how to use the barter system for doing business.
