Rhode Island Ratifies Constitution

Date: May 29, 1790 • Location: West Warwick, United States

Rhode Island becomes the last of North America's original Thirteen Colonies to ratify the Constitution and become one of the United States.

Rhode Island is a state in the New England region of the Northeastern United States. It borders Connecticut to its west; Massachusetts to its north and east; and the Atlantic Ocean to its south via Rhode Island Sound and Block Island Sound; and shares a small maritime border with New York, east of Long Island. Rhode Island is the smallest U.S. state by area and the seventh-least populous, with slightly more than 1.11 million residents as of 2025. The state's population, however, has continually recorded growth in every decennial census since 1790, and it is the second-most densely populated state after New Jersey. The state takes its name from the eponymous island, though most of its land area is on the mainland. Providence is its capital and most populous city.
