What was a consequence of the British taking over the Fur trade in the Ohio Valley?
The American Revolution was one consequence.
The French had the support of the tribes of the Ohio River and north of the Great Lakes, during the French and Indian Wars. One of the reasons for the support of the tribes was profitable trading relationships with the French. Another reason for the support was that the French were content to trade with the Indians and not settle on the tribal lands. Most of the French colonist were located in cities and depended on trade.
The tribes had fought against the British and the Americans because the British colonist were settling on tribal lands and spreading further out into the Ohio River Valley and Kentucky.
After the conquest of Canada the British took over the profitable fur trade and became allied with the tribes of the Ohio River Valley. British then opposed further settlement. The Proclamation of 1763 legally blocked settlement west of the Appalachians mountains.
The Americans not only deeply resented the Proclamation but also often violated the law bringing the American Colonists into conflict with the Ohio River Tribes and the British. The Colonists wanted new land more than anything else. The British denying them the land that the colonists had fought for in the French and Indian Wars was one of the causes of the American Revolution.
One result of the British taking over the fur trade was bring England into open conflict with its American colonies.
The Northwest Company was created. It existed from 1779 to 1821 when the Hudson's Bay Company and the Northwest Company were forced to merge.
The Northwest Company was created by several small fur traders in Montreal looking to compete with the Hudson's Bay Company. By taking their trade to the Indians they sought to successfully compete with the HBC that was based in the Hudson's Bay area. Indian fur traders came to the HBC forts to trade.
By pushing the Fur trade to the Lake Winnipeg area and establishing Fort William on the Western edge of Lake Superior they successfully challenged the HBC.
A number of violent events between Northwest Company associates and HBC associates created a situation that the British Government couldn't tolerate and they were forced to merge.
