Answer:
The Alien and Sedition Acts and the suppression of civil liberties.
Step-by-step explanation:
The Democratic-Republicans' prominent grievances were the Alien and Sedition Acts and the suppression of civil liberties. During John Adams' presidency, he signed the Alien and Sedition Acts into law, giving the government the power to deport dangerous or undesirable noncitizens, and making any criticism of the government illegal. Democratic-Republicans viewed this as an encroachment of the First Amendment.
Democratic-Republicans believed these two acts suppressed the civil liberties of American citizens by quieting dissent and political competition. Additionally, these actions were seen as an abuse of power and authoritarian practices.
