Kapu Kuialua

Kapu Kuʻialua; Kuʻialua; or just Lua; is an ancient Hawaiian martial art based on bone breaking, joint locks, throws, pressure point manipulation, strikes, usage of various weapons, battlefield strategy, open ocean warfare as well as the usage of introduced firearms from the Europeans.

The fighting art was referred to as "Kuʻialua", literally meaning two hits. That name was subsequently given to the god of this martial art. Only those associated with the aliʻi (nobility), such as professional warriors, guardsmen, and members of the royal families, were generally taught Kuʻialua. During times of warfare, the makaʻāinana (commoners) were also instructed in the basic movements and functions of the martial art.

The old warriors of this art would coat themselves with a thin layer of coconut oil and remove all of their body hair in order to be able slip away and avoid being grappled in battle. The word for Lua masters, ʻōlohe, literally means "hairless".

While living on Oʻahu, Kamehameha established three Lua schools (called pā kuʻialua) to help prevent extinction of this art. One was instructed by Hāhākea, another by Nāmakaimi, and another by Nāpuaʻuki and his assistants. This last, probably the most prominent one, taught 24 boys, including Kekūanāoʻa and John Papa ʻĪʻī of Kamehameha's court.
