The Legislature of Guam () is the law-making body for the United States territory of Guam. The unicameral legislative branch consists of fifteen senators, each serving for a two-year term. All members of the legislature are elected at-large with the island under one whole district. After the enactment of the Guam Organic Act in 1950, the First Guam Legislature was elected composing of 21 elected members. Today, the current fifteen-member 37th Guam Legislature () was elected in November 2022. History American Period: 1898–1941, 1944–present Spain lost Guam during the 1898 Spanish–American War in a bloodless invasion. For the next forty years, the United States Navy assumed executive control of the island, treating it more as a military outpost than an overseas territory, with little to no civilian say in the island's affairs. Governor Captain Willis Winter Bradley instituted the Guam Congress during the 1930s as an elected advisory body to the naval governor. On December 8, 1941, Imperial Japanese forces invaded Guam, beginning a three-year occupation of the island. The island was eventually retaken in 1944 during the intense Battle of Guam. Following the end of the war, the U.S. Navy attempted to resume military control of the islands, much to the dismay of the local Chamorro population who demanded greater rights on the heels of the harsh Japanese occupation. The U.S. federal government listened. The result was the Guam Organic Act of 1950 signed by President Harry S. Truman. The act established a civilian territorial government with executive, legislative, and judicial branches. It was the first time that Guam had a democratic civilian government.
