Indigenous heritage is a complex academic concept and interdisciplinary research domain focused on the intergenerational transmission, preservation, and contemporary expression of the distinct cultural knowledge, practices, and tangible and intangible elements belonging to Indigenous peoples worldwide. This field investigates the diverse forms of Indigenous patrimony, including languages, traditions, spiritual beliefs, social structures, knowledge systems (such as ecological and scientific understanding), arts, artifacts, and profound relationships with ancestral lands and environments, recognizing its intrinsic link to identity, self-determination, and critical significance for cultural continuity, rights, and decolonization efforts.
