Kū

Kū (often revered under the royal aspect of Kū-nui-ākea and the martial epithet Kūkaʻilimoku) is one of the four supreme foundational deities (nā akua) of traditional Hawaiian religion, sharing cosmic governance with Kāne, Lono and Kanaloa. Personification of the generative male principle, of upright verticality and of sovereign authority, Kū presided over war, political unification, mountain forests, the engineering of ocean canoes, agriculture and fishing. In the socio-religious organization of the Hawaiian islands, the state cult of Kū reached its fullest expression in the walled temples of the luakini class, erected exclusively by the supreme chiefs (aliʻi nui) in times of war or great national danger, with the aid of high-lineage priests of the Pāʻao line. In these sacred complexes, strict rites of silence and sacrifice dedicated offerings of animals, cloth and human captives to secure victory in battle and the legitimacy of the crown. Alongside the imperial liturgies of conquest, Kū was also invoked by the common people in functional, protective manifestations, such as Kū-moku-hālīʻi in the ceremonial felling of forest trees, Kū-ka-ʻōʻō in the cultivation of the land, and Kūʻula in the protection of coastal fishermen.
