Guam (gwäm)  is the largest and southernmost of the Mariana Islands. It is an unincorporated territory of the United States located in the Pacific Ocean; the residents are full U.S. citizens. The island was ceded to the United States by Spain in 1898. The United States Army and Navy maintains military bases on Guam.
In World War II, Guam was occupied by the Japanese, but American forces landed in July of 1944, and took back the island after a three week battle. Out of 18,000 Japanese troops stationed on the island, only 500 survived to become prisoners of war.
The population of Guam is estimated at 173,456 in 2007.  Chamorro and English are the primary languages spoken in Guam. The highest point in Guam is Mount Lamlam, which is 1,332 feet (406 m). The weather is usually hot and humid, ranging from 74° to 86°, with an average annual rainfall of 96 inches. Typhoons are common, especially during the months of October and November.
