In 1789, the first presidential election, George Washington was unanimously elected president of the United States. With 69 electoral votes, Washington won the support of each participating elector. No other president since has come into office with a universal mandate to lead.
Between December 15, 1788 and January 10, 1789, the presidential electors were chosen in each of the states. On February 4, 1789, the Electoral College convened. Ten states cast electoral votes: Connecticut, Delaware, Georgia Maryland, Massachusetts, New Hampshire, New Jersey, Pennsylvania, South Carolina, and Virginia. New York, however, failed to field a slate of electors. North Carolina and Rhode Island were unable to participate because they had not yet ratified the Constitution. After a quorum was finally established, the Congress counted and certified the electoral vote count on April 6.
Northerners in America, due to the new rulings of Henry Clay's Compromise of 1850, were required by law to abide strictly by the Fugitive Slave Law and report any runaway slaves they encountered to the proper authorities. This was especially stressing to the many abolitionists in the region.
