a territory of the United States (the Tutuila Islands in 1900 and officially Manu'a in 1904) and was known as American Samoa. The western islands, by far the greater landmass, became German Samoa. The United Kingdom had vacated all claims in Samoa and in return received (1) termination of German rights in Tonga, (2) all of the Solomon Islands south of Bougainville, and (3) territorial alignments in West Africa. German Samoa (1900–1914) The German Empire governed the western part of the Samoan archipelago from 1900 to 1914. Wilhelm Solf was appointed the colony's first governor. In 1908, when the non-violent Mau a Pule resistance movement arose, Solf did not hesitate to banish the Mau leader Lauaki Namulau'ulu Mamoe to Saipan in the German Northern Mariana Islands. The German colonial administration governed on the principle that "there was only one government in the islands." Thus, there was no Samoan Tupu (king), nor an alii sili (similar to a governor), but two Fautua (advisors) were appointed by the colonial government. Tumua and Pule (traditional governments of Upolu and Savai'i) were for a time silent; all decisions on matters affecting lands and titles were under the control of the colonial Governor. In the first month of World War I, on 29 August 1914, troops of the New Zealand Expeditionary Force landed unopposed on Upolu and seized control from the German authorities, following a request by Great Britain for New Zealand to perform this "great and urgent imperial service." New Zealand rule (1914–1961) From the end of World War I until 1962, New Zealand controlled Western Samoa as a Class C Mandate under trusteeship through the League of Nations, then through the United Nations. Between 1919 and 1962, Samoa was administered by the Department of External Affairs, a government department which had been specially created to oversee New Zealand's Island Territories and Samoa. In 1943, this department was renamed the Department of Island Territories after a separate Department of External Affairs was created to conduct New Zealand's foreign affairs. During the period of New Zealand control, their administrators were responsible for two major incidents. Flu pandemic In the first incident, approximately one fifth of the Samoan population died in the influenza epidemic of 1918–1919. In 1918, during the final stages of World War I, the Spanish flu had taken its toll, spreading rapidly from country to country. On Samoa, there had been no epidemic
