How did Guam get its name: When sailors from Spain came to Guam, the native Chamorro people would run out to their ships to sell fruit, calling “Guahan!”

“Guahan” means “I have,” and it sounded like “Guam” to the Spanish sailors, who named the island after this greeting.

Date admitted to the Union: Guam became a U.S. territory in 1898 after the Spanish-American War.

On August 1, 1950, the Organic Act of Guam gave U.S. citizenship to all Guamanians (people born in Guam).
