Answer 2

THE familiar labels "The Age of Jackson" and "Jacksonian Democracy" identify Andrew Jackson with the era in which he lived and with the advancement of political democracy. This honor may exaggerate his importance, but it also acknowledges the important truth that Jackson significantly contributed to shaping the American nation and its politics. Just as contemporaneous artists so often depicted him astride his horse overseeing the battlefield, Jackson bestrode some of the key currents of nineteenth-century American political life.

Jackson's presidency began on a sunny, spring-like day, 4 March 1829. Dressed in a simple black suit and without a hat, partly out of respect for his recently deceased wife, Rachel, and partly in keeping with traditions of republican simplicity, Jackson made his way on foot along a thronged Pennsylvania Avenue. From the east portico of the Capitol, he delivered his inaugural address—inaudible except to those close by—in which he promised to be "animated by a proper respect" for the rights of the separate states. He then took the oath of office, placed his Bible to his lips, and made a parting bow to the audience. With great difficulty, he made his way through the crowd, mounted his horse, and headed for the White House and what had been intended as a reception for "ladies and gentlemen."
