In the 1830s, the United States saw a shift towards Jacksonian Democracy, which emphasized the idea that sovereignty belonged to the mass of ordinary citizens, rather than a select elite based on property, race, or education. This was a departure from previous Western thought that often restricted political participation to propertied or educated classes.
