Which political party began as a pro-Jackson party that valued small government and states' rights?

The Democratic Party originated as a pro-Jackson party in the early 19th century, particularly during the presidency of Andrew Jackson. This party emerged from the Democratic-Republican Party, which was founded by Thomas Jefferson. The core principles of the Democratic Party during its early formation included a strong emphasis on agrarian interests, small government, and states' rights. Andrew Jackson championed these values, advocating for the common man and opposing what he saw as the elite interests represented by the opposing Whig party.

Under Jackson's leadership, the Democratic Party distinguished itself by promoting individual liberties and a limited federal government, allowing for greater power to be vested in the states. This philosophy highlighted the importance of local governance and the belief that state and local authorities should have substantial control over their own affairs, reflecting the party's foundational values. As such, the Democratic Party has continued to uphold many of these principles throughout its history.
