Royal monograms were used by Hawai‘i’s monarchs as identification marks to personalize items such as stationery paper, envelopes, clothing accessories like belt buckles, buttons, and calabashes.

The monogram was composed of the letters or initials of the monarch's name or official title, which were then interwoven or combined into a design.

The royal monograms pictured, from left to right, belonged to:
Queen Emma, King Kamehameha V, King Kalākaua & Queen Lili‘uokalani.
