The Native Hawaiians initially began with a culture that was similar to their Polynesian roots, but with time and isolation, began to develop their own unique system of spiritual worship and cultural practice. This new worship centered around the ideas of land, aina, and family, ohana, with land being held as a sacred part of life and family going beyond blood. These concepts are very different from Western views of familial structure and ownership. Much of this changed during the imperialist allotment system, and familial relations were also changed by US settler policies. The Hawaiian culture is polytheistic oriented but mostly focuses on two gods. These are Papa and Wakea, the mother and father of the Hawaiian islands, whose stillborn child formed the deep roots of Hawaii, and whose second child, Halao, is the god from which all Hawaiians originate.
