Bureau of Insular Affairs

The Bureau of Insular Affairs was a division of the United States Department of War that oversaw civil aspects of the administration of several territories from 1898 until 1939.

The bureau was created 13 December 1898 as the Division of Customs and Insular Affairs within the Office of the Secretary of War. This followed the Spanish–American War, which resulted in the transfer of several areas from Spain to the United States, including the Philippines, Puerto Rico, and Cuba. The bureau supervised the customs and civil affairs of these areas. The word "insular" was already associated with Cuba and Puerto Rico because the Spanish had created autonomous "insular" governments for both islands in February 1898.

In 1900, the name was changed to Division of Insular Affairs, and in 1902 it became the Bureau of Insular Affairs. As a result of the Insular Cases, the U.S. Attorney General issued an opinion in 1915 stating that the insular areas were unincorporated territories of the United States. In 1939, the bureau was replaced by the Division of Territories and Island Possessions in the Department of the Interior. This division was later renamed the Office of Insular Affairs.

From 1898 to 1900 and again in 1909–1934, the Bureau was responsible for the administration of Puerto Rico, called "Porto Rico" in official U.S. government documents until 1932. Puerto Rico, also an unincorporated territory of the United States, was administered under a civil government created by the Foraker Act of 1900, amended by the Jones–Shafroth Act of 1917. In 1934, the Bureau's functions for Puerto Rico were transferred to the Division of Territories and Island Possessions (later the Office of Territories and still later the Office of Territorial Affairs) within the Department of the Interior.
