German Samoa (German: Deutsch-Samoa) was a German protectorate from 1900 to 1914, consisting of the islands of Upolu, Savai'i, Apolima and Manono, now wholly within the independent state Samoa, formerly Western Samoa. Samoa was the last German colonial acquisition in the Pacific basin, received following the Tripartite Convention signed at Washington on 2 December 1899 with ratifications exchanged on 16 February 1900. It was the only German colony in the Pacific, aside from the Kiautschou concession in China, that was administered separately from German New Guinea.

In 1855 J.C. Godeffroy & Sohn expanded its trading business into the Pacific following negotiations by August Unshelm, Godeffroy’s agent in Valparaiso, He sailed out to the Samoan Islands, which were then known as the Navigator Islands. During the second half of the 19th century German influence in Samoa expanded with large scale plantation operations being introduced for coconut, cacao and hevea rubber cultivation, especially on the island of 'Upolu where German firms monopolized copra and cocoa bean processing.

Samoa (ⁱ/səˈmoʊ.ə/; Samoan: Sāmoa, IPA: [ˌsaːˈmoa]), officially the Independent State of Samoa (Samoan: Malo Sa'oloto Tuto'atasi o Sāmoa), formerly known as Western Samoa, is a country encompassing the western part of the Samoan Islands in the South Pacific Ocean. It became independent from New Zealand in 1962. The two main islands of Samoa are Upolu and one of the biggest islands in Polynesia, Savai'i. The capital city, Apia, and Faleolo International Airport are situated on the island of Upolu.

Samoa was admitted to the United Nations on 15 December 1976. The entire island group, inclusive of American Samoa, was called Navigators Islands by European explorers before the 20th century because of the Samoans' seafaring skills.

The oldest date so far from pre-historic remains in Samoa has been calculated by New Zealand scientists to a likely true age of circa 3,000 years ago from a Lapita site at Mulifanua during the 1970s.

The origins of the Samoans is closely linked to modern research about Polynesia in various scientific disciplines such as genetics, linguistics and anthropology. Scientific research is ongoing although a number of different theories exist; including one proposing that the Samoans originated from Austronesian predecessors during the terminal eastward Lapita expansion period from Southeast Asia and Melanesia between 2,500 and 1,500 BCE. The Samoan origins are currently being reassessed due to new scientific evidence and carbon dating findings from 2003 and onwards.
