The emancipation proclamation issued by president Lincoln freed all of the slaves in the United States during the Civil War--although many remained enslaved illegally in the South.
Federalists basically wanted a big government, whereas anti-federalists did not they wanted a very small central government. This inspired a few individuals to create the federalists papers, which basically entailed what was actually happening in the consititutipn.
Your ending the trade of slaves and ending slavery would be ending owning a slave at all.
In the early 19th century, settlers could travel from 15 to 20 miles per day by covered wagon. Given the distance between New York and California is around 2,445 miles, the journey would take approximately 122 to 162 days, or from 4 to 5.5 months.
Have a great day!~ <3
