The Insular Government of Porto Rico[1] (Spanish: Gobierno Insular de Puerto Rico), known as the Insular Government of Puerto Rico[2][3][4] after May 17, 1932,[5] was an unincorporated and organized territory of the United States that was established when the Foraker Act became effective on April 12, 1900.

The Insular Government was preceded by the Military Government of Porto Rico and was followed by the Commonwealth of Puerto Rico.

From 1901 to 1922, the U.S. Supreme Court wrestled with the constitutional status of these governments in the Insular Cases.

[6] The Foraker Act was superseded on March 2, 1917, by the Jones–Shafroth Act, which granted U.S. citizenship to anyone born in Puerto Rico on or after April 11, 1899.

On July 25, 1952, Puerto Rico became a commonwealth after the ratification of the Constitution of the Commonwealth of Puerto Rico.
