In Māori mythology, Tū or Tūmatauenga (Māori: 'Tū of the angry face') is one of the great gods, the origin of War and Balance. All war-parties were dedicated to him, and he was treated with the greatest respect and awe. He is usually a son of the primordial parent, sky and earth (see Rangi and Papa). In a Te Arawa version, Tūmatauenga advises his brothers to kill their parents Rangi and Papa in order to allow light and space into the world, but the kinder proposal of Tāne is accepted and instead the primordial pair are forced apart. Tūmatauenga thinks about the actions of Tāne in separating their parents, and makes snares to catch the birds, the children of Tāne, who can no longer fly free. He then makes nets, and traps the children of Tangaroa. He makes hoes to dig the ground, capturing his brothers Rongo and Haumia-tiketike, heaping them into baskets to be eaten. The only brother that Tūmatauenga cannot subdue completely is Tāwhirimātea, whose storms and hurricanes attack humankind to this day because of his indignation at the actions of his brothers (Grey 1971:7-10).
Although Rangi and Papa were not human in form, Tūmatauenga and his brothers were. Humankind - the descendants of Tū - increased upon the earth, until the generation of Māui and his brothers (Grey 1956:8-11, Tregear 1891:540).
Tūmatauenga's actions provide a pattern for human activities. Because Tūmatauenga defeated his brothers, people can now, if they perform the appropriate rituals, kill and eat birds (the children of Tāne), fish (the children of Tangaroa), cultivate and harvest food plants (the children of Rongo and Haumia-tiketike), and generally harness the resources of the natural world. Tūmatauenga is also the originator of warfare, and people make war now because Tūmatauenga provided the example. When rituals were performed over warriors before a battle, or when an infant was dedicated to a future role as a fighter, Tūmatauenga was invoked as the source of their duty. The body of the first warrior to fall in a battle was often offered up to Tūmatauenga. While Tūmatauenga is the origin of war, powerful local deities such as Kahukura, Maru or Uenuku were also called upon in time of war (Orbell 1998:185-186).
