What happened during when George Washington's was president Like Why did tensions between Western settlers and Native Americans increase during Washingtons presidency?

During the presidency of George Washington (1789-1797), tensions between American settlers and Natives increased primarily for one reason: still more settlers passed from the American East Coast into the 'wild western' lands beyond the Appalachian Mountains, thereby increasing contact (and friction) with the resident Natives. This movement was due in part to the intentional encouragement of westward settlement by the United States government, particularly in light of the continuing British presence in what was at the time largely called the 'Northwest Territory.'
