when did the era of jacksonian democracy begin
This era, called the Jacksonian Era (or Second Party System) by historians and political scientists, lasted roughly from Jackson's 1828 election as president until slavery became the dominant issue in 1854 and the American Civil War dramatically reshaped American politics. It emerged when the long-dominant Democratic-Republican Party became factionalized around 1824. Jackson's supporters began to form the modern Democratic Party and rivals John Quincy Adams and Henry Clay, created the National Republican Party, which would soon combine with other anti-Jackson elements to form the Whig Party.
