Historians and political scientists use Second Party System to periodize the political party system operating in the United States from about 1828 to 1854, after the First Party System ended. The system was characterized by rapidly rising levels of voter interest, beginning in 1828, as demonstrated by Election Day turnouts, rallies, partisan newspapers, and high degrees of personal loyalty to parties.

In the United States House of Representatives elections in 1828 and 1829, the Jacksonians soundly took control of the presidency, with Andrew Jackson's victory, and greatly increased their majority in Congress. Outgoing President John Quincy Adams's unpopularity played a major role in the Jacksonian pick-up, as did the perception of the Anti-Jacksonian Party as urban and elitist. Major increases in suffrage also heightened Jacksonian wins, as newly enfranchised voters tended to associate with Jacksonian principles. The Anti-Masonic Party, a single issue faction based on distrust of Freemasonry, became the first third party in American history to garner seats in the House.

Henry Clay Sr. was an American attorney and statesman who represented Kentucky in both the Senate and House. He was the seventh House Speaker and the ninth Secretary of State. He received electoral votes for president in the 1824, 1832, and 1844 presidential elections. He also helped found both the National Republican Party and the Whig Party. For his role in defusing sectional crises, he earned the appellation of the "Great Compromiser" and was part of the "Great Triumvirate."

The Democratic Party is the oldest voter-based political party in the world and the oldest existing political party in the United States. The party's modern institutions were formed in the 1830s and 1840s, but it traces its history and heritage back to Thomas Jefferson and James Madison's Democratic-Republican Party of the 1790s–1820s. Known as the party of the "common man,” the early Democratic Party stood for individual rights and state sovereignty, but opposed banks and high tariffs. During the Second Party System under Presidents Andrew Jackson, Martin Van Buren and James K. Polk, the Democrats usually bested the opposition Whig Party by narrow margins.

Andrew Jackson was an American soldier and statesman who served as the seventh president of the United States from 1829 to 1837. Before being elected to the presidency, Jackson gained fame as a general in the United States Army and served in both houses of the U.S. Congress. As president, Jackson sought to advance the rights of the "common man" against a "corrupt aristocracy" and to preserve the Union.

James Knox Polk was the 11th president of the United States, serving from 1845 to 1849. He previously was Speaker of the House of Representatives (1835–1839) and governor of Tennessee (1839–1841). A protégé of Andrew Jackson, he was a member of the Democratic Party and an advocate of Jacksonian democracy. Polk is chiefly known for extending the territory of the United States during the Mexican–American War; during his presidency, the United States expanded significantly with the annexation of the Republic of Texas, the Oregon Territory, and the Mexican Cession following the American victory in the Mexican–American War.

The presidency Andrew Jackson began on March 4, 1829, when Andrew Jackson was inaugurated as President of the United States, and ended on March 4, 1837. Jackson, the seventh United States president, took office after defeating incumbent President John Quincy Adams in the bitterly contested 1828 presidential election. During the 1828 presidential campaign, Jackson founded the political force that coalesced into the Democratic Party during Jackson's presidency. Jackson won re-election in 1832, defeating National Republican candidate Henry Clay by a wide margin. He was succeeded by his hand-picked successor, Vice President Martin Van Buren, after Van Buren won the 1836 presidential election.
