If you've seen a Hawaiian tourism commercial, a beach movie, or even a cartoon with Daffy Duck in a lei and a grass skirt, you've heard the poignant strains of "Aloha Oe."

But the tune has a history stretching far beyond cartoons and commercials: It was composed in 1878 by the woman who would become the last queen of Hawaii, Lili'uokalani.

Hawaii is the only state to have once been an independent monarchy. And when Lili'u, as she called herself, was born in 1838, it was at its height.
