1 French lost control of Canada and new taxes were instituted on American colonists to help cover cost of the war.
2 and 3 Roughly, the NW Territory was Ohio, Indiana, part of Michigan and Wisconsin and Illinois. Everything north of the Ohio River. Created to provide for settlement in the what was then the far west and control the Indian populations who were terrorizing the frontiers of the original 13 colonies.
4 It was remote and there were dangers from Indians and French forces that continued to operate in the area for years after the US was formed as a nation. Remember, St. Louis was a large French garrison (fort) until after 1800 and the Louisiana Purchase. They guarded the upper Mississippi and the junction of the Ohio and the Mississippi. They were the only power in the region capable of controlling the territory.
5 Regulated land sales basically and explained how territory status and statehood could be achieved. These conditions were still working 130 years later in Arizona statehood (1912) and in the 1950's when we admitted Alaska and Hawaii as states. Same rules as 1783, when it was passed. Sorry about reversing the answer order on you:(
6 50,00 residents to get territory status
7 We would have a large French settlement on the western side of the Appalachian Mountains, assuming the US had not taken the territory after our own revolution. We would be a smaller, less populous nation more like, say, Guatemala or Panama or perhaps Mexico.
8 Ohio basically as we did not extend all the way to the Mississippi in the west.
40 years of doing these questions in role as teacher.
