Which of the following was the first state to ratify the U.S. Constitution?

Delaware was the first state to ratify the U.S. Constitution on December 7, 1787. This quick and decisive action is significant as it set a historical precedent for the other states in the ratification process. Delaware's status as the first state is often celebrated and is an essential part of its identity; the state is sometimes referred to as "The First State."

By being the first to ratify, Delaware played a crucial role in the establishment of the federal government, demonstrating its commitment to a unified nation under the Constitution. The other states mentioned followed Delaware's lead in subsequent order, but none did so before Delaware. This pivotal moment underscored the collaborative effort required by the original thirteen states to form the United States as we know it today.
