The 1824 election caused several changes to American presidential politics. It was the end of the system of Congressional caucuses for nominating candidates. From 1800 to 1820, Congressional caucuses selected presidential candidates. There was very little direct voter involvement in the system. But in 1824, only one candidate was selected by a caucus. The other candidates decided to appeal directly to the people. This led to a major change in the system. By the 1830s politics had become a subject of wide national interest.
