The cult of Lili'uokalani is a powerful propaganda tool calling for either racial separatism (tribe) or ethnic nationalism (secession), depending on the activist's preference.  Celebrating Lili'uokalani is a polite way to protest the overthrow of the monarchy, to express anti-haole feelings without appearing to be blatantly racist.

Lili'uokalani reigned for less than 2 years, and was a miserable failure.  But as the last monarch, and the "victim" of the overthrow, all the activists rally to her as Catholics rally to the Virgin Mary.  Some pray to her as to a saint.  Some believe everything in her book is the gospel truth, and protest angrily if anyone dares to challenge anything in it.
