Final answer:
A diverse group of people, symbolizing Andrew Jackson's populist appeal, came to celebrate his inauguration, marking a shift toward a more populist and democratic era in American politics.
Step-by-step explanation:
The types of people who came to Washington to celebrate Andrew Jackson's inauguration were representative of a wide spectrum of American society at the time. The celebration marked the dawn of the Age of Jackson and the ascension of the Democratic party. It was a diverse group that included urban workers, small northern farmers, southern yeomen, and southern planters. This wide array of supporters signified Jackson's populist appeal and his portrayal as a champion of the common man against the established elites. The festivities at the White House were rowdy and inclusive, contributing to a sense of a more populist and democratic era in American politics. The large crowds and the subsequent chaos during the celebrations were symbols of both the inclusive nature of Jackson's presidency and the turbulence of the emerging democratic style of that era.
