The Manifest Destiny which stated that the U.S. had a God-given right to all of the land in North America
The subject of the great compromise was how the congress would deal with legislation. It was a debate whether the states should be equally represented, or should they be represented based on the size of the state, that is, on the size of the population. The decision was to have a compromise and have a bicameral government where both systems would be implemented in the best interest of all states with the senate having equal representation, and the house having population representation.
They decided that for now slavery would be legitimate and legal, but in the future the Congress would decide the future of slavery in the country. The 3/5ths compromise was important in this because of how slaves would account for during census when it comes to representation. In the future however we know what the congress did and how slavery was first forbidden in the North, and then later in the south as well.
Congress may not suspend "habeas corpus" unless a national crisis requires it, since this is one of the most fundamental human rights that the Founding Fathers wanted to protect. It has very rarely been suspended, with one of the most notable times taking place under Lincoln in the Civil War.
After the revolutionary war, the USA formed a confederacy its a loose union of independent states. hope this helps :)
