Along with the nearby island of Tanambogo, it played an important role in the Guadalcanal campaign during World War II. In 1942 the Japanese attempted to establish a seaplane base on the island. On 7–9 August 1942, in the Battle of Tulagi and Gavutu–Tanambogo, the 1st Marine Parachute Battalion and elements of the U.S. 2nd Marine Regiment assaulted and occupied the island.
