Pennsylvania Ratifies the Constitution
Pennsylvania became the second state to ratify the U.S. Constitution, just five days after Delaware. The ratification convention voted 46 to 23 in favor, though Anti-Federalists raised concerns about the lack of a bill of rights.
Why It Matters
Pennsylvania's ratification was critical as it was the largest and most politically influential state to approve the Constitution early in the process, building momentum for adoption.
