The French and the British had a conflict over the Ohio river valley because of the control over fur trading. The Britishers tried to take the business away from the French by offering the locals more goods against fewer furs. The French had originally taken control over the Ohio river valley before the Britishers tried to get entry into the valley. The French did not take this heavy handedness of the Britishers lightly and so they started creating a line of forts. These forts were built to protect the fur traders from the invading Britishers. Many British settlers also started ariving in the Ohio river valley and this was not taken gladly by the French.
