The first insular areas that occupied the United States were Baker Island, Howland Island and Navassa Island (1857) then Johnston Atoll and Jarvis Island (both in 1858) would be claimed. After the War between the United States and Spain in 1898, several territories were taken that are still under U.S. sovereignty (Puerto Rico and Guam, both in 1898). Palmyra Atoll was annexed along with the Republic of Hawaii (formerly a Kingdom) that same year. American Samoa was reclaimed the following year (1899). In 1917, at the height of World War I, Denmark sold the Danish Virgin Islands to the United States.
