The Samoan Islands () are an archipelago covering in the central South Pacific, forming part of Polynesia and of the wider region of Oceania. Administratively, the archipelago comprises all of the Independent State of Samoa and most of American Samoa (apart from Swains Island, which is geographically part of the Tokelau Islands).

The population of the Samoan Islands is approximately 250,000.

Samoan Islands

The oldest known evidence of human activity in the Samoan Islands dates to around 1050 BCE. It comes from a Lapita site at Mulifanua wharf on Upolu island. In 1768, the eastern islands were visited by the French explorer Bougainville, who named them the Navigator Islands. That name was used by missionaries until about 1845, and in official European dispatches until about 1870.

Political partition

In the late 19th century, competition for political control of the islands between the United States, Germany, and the United Kingdom resulted in the December 1899 Tripartite Convention, which formally partitioned the Samoan archipelago into a German colony (German Samoa) in the western half and a United States territory (American Samoa) in the eastern half. New Zealand began occupying the western islands in World War I, while they were still a German colony and continued as an occupying force until 1920. Then, from 1920 until Samoa's independence in 1962, New Zealand governed the islands in that group under a League of Nations Class C Mandate from 1920 to 1946, and as a United Nations Trust Territory from 1946 to 1962. The force that eventually led to the political independence of the western islands in 1962 was the pro-independence Mau movement, which gained popularity across the area. The eastern islands remain a political territory of the United States.
