Keetoowah Nighthawk Society
The Keetoowah Nighthawk Society (Cherokee: ᎩᏚᏩ ᎤᎾᏙᏢᎯ) was a Cherokee nationalist organisation formed in 1858 and re-established ca. 1900 that intended to preserve and practice traditional Cherokee spiritual beliefs and "old ways" of tribal life, based on religious nationalism.
