Why did democratic republicans criticize the U.s constitution during its creation?

Democratic-Republicans criticized the U.S. Constitution during its creation primarily because they believed it concentrated too much power in the federal government, undermining states' rights and individual liberties. They feared that a strong central government could lead to tyranny and a loss of democratic principles. Additionally, they argued for the inclusion of a Bill of Rights to protect citizens' freedoms, which they felt was essential for safeguarding against potential governmental overreach.
