It is interesting to note that the royalty of Hawai'i articles are not titled according to Wikipedia naming standards:

1. Pre-emptively disambiguate the names of monarchs, of modern countries in the format "{Monarch's first name and ordinal} of {Country}". Examples: Edward I of England; Alfonso XII of Spain; Henry I of France.*

And yet:

• Kamehameha I


• Kamehameha II


• Kamehameha III


• Kamehameha IV


• Kamehameha V


• Lunalilo


• Kal?kaua


• Liliuokalani

I wonder if this is due to the need to recognize the USA's gunpoint diplomacy in capturing Hawai'i if Wikipedia recognized Hawai'i as a kingdom no greater or lesser than any European throne.
