Andrew Jackson felt betrayed by his loss in 1824 and wanted to create a political party for the "common people."

Explanation:

In 1824 the Democratic-Republican Party, which ruled the United States since the early nineteenth century, entered into crisis. Four candidates for the presidency were presented, including General Andrew Jackson, who won the most votes, but did not reach the majority. The House of Representatives decided in favor of John Quincy Adams, according to Jackson and his followers, unfairly. Four years later, the "Jacksonian" party won the victory of the popular Anglo-American War hero of 1812. The inauguration shocked the political elite, who saw a crowd of poor people arrive in the White House gardens. In 1832 the new president's party officially became the Democratic Party.
