Changes

The 50th and so far final state, [[Hawaii]], was admitted in 1960, 67 years after other American settlers deposed the last native [[queen]] of the archipelago and 62 years after annexation had become politically feasible as a result of the [[Spanish-American War]], in which the United States also annexed [[Puerto Rico]], [[Guam]] and [[Wake Island]].  The last three islands are not states, although [[Puerto Rico]] has occasionally held non-binding [[referenda]] to express its desired status within the United States.
