How did the U.S. change under the Democratic-Republicans?
Under the Democratic-Republicans, who took the presidency in the election of 1800, the United States gradually became more democratic and somewhat less centralized. These were characteristics of the Democratic-Republicans.
The immediate effect of their government was to repeal the Alien and Seditions Acts (thus increasing levels of democracy) and the whiskey tax (thus reducing federal control of people in the states). These trends continued under Democratic-Republican leadership. They did so to the extent that, by the 1820s, all white men who were of age could vote and a man like Andrew Jackson could become president.
