Indigenous settlement Chuuk was first settled by
Austronesians, believed to be from the
Lapita culture of
Island Melanesia. Archaeological evidence indicates that islands of
Feefen and Wééné Islands had human settlements in the second and first century BCE. Later evidence indicates that widespread human settlements appeared in Chuuk during the 14th century CE, as the
Chuukese culture was formed.
Spanish colonization The first sighting recorded by Europeans was made by the Spanish navigator
Alvaro de Saavedra on board the
Florida during August or September 1528. They were later visited by the Spaniard
Alonso de Arellano on 15 January 1565 on board the galleon patache San Lucas. As part of the
Caroline Islands, Truk was claimed by the
Spanish Empire, which struggled to control the islands in the late 19th century. The Chuuk Lagoon was then inhabited by
Chuukese people (an
Austronesian group) that participated in intermittent wars, as well as a small population of foreign merchants and missionaries, mostly linked to the
Catholic Church. Spanish control over the islands was in part nominal. The Spanish stopped to raise a flag over Chuuk in 1886, and returned in 1895 as part of an attempt to assert control and negotiate peace between the tribes of Chuuk. No major Spanish settlement was established and traditional life continued until the German colonial era.
German and Japanese rule The Caroline Islands were sold to the
German Empire in 1899, after Spain withdrew from the Pacific after the
Spanish–American War in which it lost its main colony in Asia, the
Philippines. Germany incorporated the territory into its domain in the
German New Guinea. During
World War I, the
Imperial Japanese Navy was tasked with pursuing and destroying the
East Asia Squadron of the
Imperial German Navy and protecting the shipping lanes of
Allied trade in the Pacific and Indian Oceans. During the course of this operation, the Japanese navy seized German possessions in the Mariana Islands, the Carolinas, the Marshall Islands and Palau groups by October 1914. Chuuk then became a possession of the
Empire of Japan under the
South Seas Mandate of the
League of Nations after the defeat of Germany in World War I.
United States rule Chuuk was one of six districts of the
Trust Territory of the Pacific Islands (TTPI) which were administered by the United States under charter from the
United Nations from the end of the Second World War to the mid-1980s. The termination of U.S. administration of the Chuuk, Yap, Kosrae, Pohnpei, and Mariana Islands districts of the TTPI occurred on 3 November 1986.
Independence The
Federated States of Micronesia, including Chuuk, Yap, Kosrae, and Pohnpei, was established in 1979 and signed a
Compact of Free Association with the U.S. (effective 3 November 1986). As of recent times, Chuuk has been pushing harder for
independence. An independence referendum was originally scheduled to coincide with federal elections on 3 March 2015, but was pushed back to 5 March 2019. The
independence referendum was further pushed back to March 2022, with a date to be announced, while the constitutional legality of the proposed secession is determined. ==Geography==
