Martin Van Buren was a staunch Democrat and Andrew Jackson’s chosen successor. The other four Presidents were all members of the Whig Party at the time of their inauguration. Although it is worth noting that President John Tyler blocked so much Whig legislation that he was expelled from the Whig Party during his presidency. 

As part of the Compromise of 1850, all runaway slaves, at their capture, were to be returned to their masters.  Abolitionists called it the "Bloodhound Law" because of the bloodhounds used in the barbaric hunt.

During the time of Washington, then Jefferson and the Democratic-Republicans, the rights of “civilized” Native American organizations to remain effectively autonomous within the United States was guaranteed and upheld; however, when Andrew Jackson came into the Presidency he sought to undo this trend. In a speech in 1829 he argued for the removal of Native Americans to lands west of the Mississippi. The plan was met with general support by the American public, particularly those in the South, who desired bountiful Indian farming land. Jackson was notably opposed by Christian missionaries and a young Abraham Lincoln. Nevertheless, the bill passed Congress in 1830, and for the next two decades Native American groups all along the Eastern Seaboard were evicted from their lands and forced to migrate westwards.

Although the Thirteenth Amendment abolished slavery, it was the Fifteenth Amendment that gave black men the right to vote. All women did not receive the right to vote until 1920 with the ratification of the Nineteenth Amendment.
