American Revolutionary War :)
Hi!
I have the answer you're looking for. I just went over this in History.
The Tenth Amendment was added to the Constitution of 1787 largely because of the intellectual influence and personal persistence of the Anti-Federalists and their allies. It's quite clear that the Tenth Amendment was written to emphasize the limited nature of the powers delegated to the federal government.
Hope this helps!

Agricultural communities settled where they did because there was a water source near by for growing crops. It is very hard to grow plants or raise animals without a water source. People also settled near water sources so they could travel on ships and trade with other communities along the same water source. The people in the community also needed water to stay hydrated and to wash dirty clothes or to bathe.
