By Preservation Maryland
On April 28, 1788, Maryland became the seventh state of the United States of America. After the Articles of Confederation had failed, the U.S. needed a new governing document. The nation’s leaders proposed a federal Constitution to replace it. The U.S. Constitution was drafted and sent out to the thirteen states for ratification; nine needed to ratify it in order for it to pass. Maryland was the seventh colony to approve the new Constitution.
