The presence of external laws, claims and cultural mores either potentially or actually act to variously constrain the practices and observances of an indigenous society. These constraints can be observed even when the indigenous society is regulated largely by its own tradition and custom. They may be purposefully imposed, or arise as unintended consequence of trans-cultural interaction. They may have a measurable effect, even where countered by other external influences and actions deemed beneficial or that promote indigenous rights and interests.
