What political party was formed under the leadership of Andrew Jackson advocating for a more democratic government?

The political party formed under the leadership of Andrew Jackson that advocated for a more democratic government is the Democrats. This party emerged in the early 1820s and was particularly focused on expanding suffrage to more white males and decentralizing political power, which was a significant shift from the earlier elite-dominated Federalist and Democratic-Republican parties. Jackson's vision emphasized the importance of the common man and sought to diminish the influence of established elites, thereby fostering a more participatory form of democracy in the political landscape of the United States. This focus on populist ideals and broader representation played a critical role in shaping the Democratic Party’s identity and political strategies in subsequent years.
