The area of Rhode Island was part of the original territory of the United States. An original patent was granted for the Providence Plantations in 1643, and a charter was granted for the Colony of Rhode Island and Providence Plantations in 1663. Rhode Island ratified the U.S. Constitution on May 29, 1790; it was the 13th of the original 13 states to join the Union, with generally the same boundary as the present state. However, there were changes to the boundary between Rhode Island and Massachusetts in 1862, and additional changes from a resurvey of that boundary in 1897. The official name of the state is "State of Rhode Island and Providence Plantations."
