Final answer:
The term for wealth generated through trade or accumulation from others in the historical context provided is mercantilism, which sought to increase a nation's wealth through state-controlled trade and exploitation of colonies.
Step-by-step explanation:
The term used to describe wealth generated by trade or by accumulating it from others is mercantilism. This economic philosophy dominated European trade practices from the 1500s to the late 1700s. Mercantilism advocated for a nation to increase its wealth by obtaining gold and silver and maintaining a favorable trade balance, often through trade monopolies and colonial exploitation.
Mercantilist nations did not believe in free trade but rather in state control over trade to benefit the nation's own interest. This often resulted in wealth accumulation at the expense of other nations and the colonies. Additionally, it led to the encouragement of domestic manufacturing and development of shipping capabilities to further strengthen the nation's economic position.
