The Spanish explorer Alonso de Salazar landed in the Marshall Islands in 1529. They were named by Krusenstern, after English explorer John Marshall, who visited them together with Thomas Gilbert in 1788, en route from Botany Bay to Canton (two ships of the First Fleet). In 1905 the British government transferred some administrative responsibility over south-east New Guinea to Australia (which renamed the area "Territory of Papua"); and in 1906, transferred all remaining responsibility to Australia. The Marshall Islands were claimed by Spain in 1874. Germany established colonies in New Guinea in 1884, and Samoa in 1900. The United States also expanded into the Pacific, beginning with Baker Island and Howland Island in 1857, and with Hawaii becoming a U.S. territory in 1898. Disagreements between the US, Germany and UK over Samoa led to the Tripartite Convention of 1899.
