When did all of the Indian tribes become part of the United States and cease to be considered independent nations – in 1796, 1830, or 1871?

Answer: 1871. (By a congressional act that year, all of the American Indian tribes became, for the first time, part of the United States.)

When did the last of the Southern states outlaw the importation of slaves – 1798, 1828, or 1865?Answer: 1798. (Georgia was the last of the Southern states to outlaw the importation of slaves, primarily for economic reasons. In the decade that followed, however, South Carolina temporarily dropped her restrictions and imported 39,000 slaves before importation was federally prohibited in 1807.)

Did the Founding Fathers visualize the Constitution operating for a huge nation covering the entire North American continent, or were they thinking of a relatively small federation of states along the Atlantic seaboard?Answer: They were thinking of a huge nation encompassing the entire North American continent. (They were very disappointed when Canada did not become part of the Union. Nevertheless, John Adams said he expected that eventually their constitutional system of government would be serving at least two hundred to three hundred million “freemen.”)
