Naval Government of Guam

The Naval Government of Guam was a provisional military government and later unincorporated, unorganized territory of the United States that was established during the Spanish–American War in 1898. It was under the administration of the United States Department of the Navy until the territory of Guam was organized in 1950.

History
On June 21, 1898, the United States captured Guam in a bloodless landing during the Spanish–American War. The island was ceded to the United States by Spain on April 11, 1899, by the Treaty of Paris.

On December 23, 1898, Guam was placed under the administration of the United States Department of the Navy by President William McKinley for military protection and government. Between the American capture of Guam and installation of a Naval Governor in August 1899, there was a flux in governance of the island.

In 1922, the Naval Government banned the Chamorro language in schools and workplaces and destroyed all Chamorro dictionaries.

Between 1941 and 1944, the island was under occupation by Imperial Japanese forces during World War II.

On August 1, 1950, the Guam Organic Act of 1950 was signed into law by President Harry S. Truman, making Guam an organized territory.
