The United States was brought into existence by the often brutal conquest of lands that belonged to Native Americans, but it also formally annexed certain territories. The U.S. annexed Hawaii in an 1898 treaty advanced by President William McKinley despite local opposition and mass protests. The Pacific archipelago was a U.S. territory until 1959, when Hawaii became the 50th state. (AP Photo/Byron Rollins, File)
