Puerto Rico in the United States

Constitutional Status of Puerto Rico

According to the Encyclopedia of the American ConstitutionPuerto Rico is the largest of the United States insular areas, both as to land area and population. It is also one of the oldest in terms of being part of the United States, having been acquired along with Guam in 1899 as a result of the Spanish American War. See the Foraker Act of 1900.

The Encyclopedia says that no “clear definition exists of how and to what extent the Commonwealth of puerto rico fits within the federal constitutional system.” See the Puerto Rican Federal Relations Act, enacted by Congress in 1950 “in the nature of a compact” between Congress and Puerto Rico.
