Final answer:
President Andrew Jackson was instrumental in establishing the Democratic Party, which emerged in the election of 1828 and advocated for the interests of the common people and a government that reflected the majority's will.
Step-by-step explanation:
President Andrew Jackson helped establish the Democratic Party. This occurred during the period known as the Age of the Common Man, which coincided with Jackson's presidency. The Democratic Party, formed from the Democratic-Republicans, reflected Jackson's advocacy for the common people, opposing a national bank and championing westward expansion. The emergence of the Democratic Party represented a shift in political dynamics in the United States as part of the second party system that replaced the first one. The party believed that the government should mirror the will of the majority and promote the common citizen's interests. Consequently, in the election of 1828, with a surge in democratic spirit and voter participation, Andrew Jackson's election marked the consolidation of the Democratic Party's influence in American politics.
