At Andrew Jackson's 1828 inauguration, hundreds of bearded, buckskin-clad frontiersmen trashed the White House while celebrating the election of one of their own to the Presidency. Though born in South Carolina, Jackson, like many others, had moved to the frontier. Indeed, America was a country on the move west. On July 4, 1826, less than two years before King Andrew ascended to the throne, the Yankee John Adams and the aristocratic Virginian Thomas Jefferson both passed away.
Andrew Jackson's Firsts. Andrew Jackson was the seventh president of the United States, but he was the first in many other ways. Introduction. Born in poverty, Andrew Jackson (1767-1845) had become a wealthy Tennessee lawyer and rising young politician by 1812, when war broke out between the United States and Britain. His leadership in that conflict earned Jackson national fame as a military hero, and he would become Americaâs most influentialâand polarizingâpolitical figure during the 1820s and 1830s.
