protection in 1875.

In 1887，the United States was given permission to set up a naval base in Hawaii at Pearl Harbor. Later，the King was overthrown(推翻)，and Hawaii was founded as a republic in 1893. The US control of the islands came five years later，when the United States annexed(兼并)Hawaii and it became a US region in 1900.

Under the influence of the US，the population of Hawaii grew and its economy grew as well，as the islands increased sugar and pineapple production to satisfy the US mainland. Hawaii's importance as a military station became important when Japan attacked Pearl Harbor on December 7,1941. This brought the United States as well as Hawaii into World War Ⅱ.

Following the war's end in 1945，the state took a long journey toward statehood. On August 21,1959，Hawaii was admitted to the union as the 50th state of the US.
