What issue was standing the way of the u. s. to gaining the territory in the northwest?

The British victory in the Seven Years’ War was confirmed in the Treaty of Paris in 1763, in which, among many other things, the French surrendered their claim to the Old Northwest. Later, during the War for Independence, American interests in the area were advanced by the military exploits of George Rogers Clark. Control of the area passed from Britain to the new United States in the Treaty of Paris of 1783. I hope this helped you!...

The growth of the empire continued to increase their confidence.
