Guam was ceded to the U.S. following the Spanish-American War in 1898. The island was captured by Japan on December 10, 1941 and occupied for two years. On July 21, 1944, Guam was liberated by the United States. The island became, and remains to this day, an unincorporated territory of the United States. Liberation Day remains one of the most celebrated holidays on Guam.
