Ancestral remains collected within the colonial context can be found across numerous, very different institutions and collections in the Netherlands. These span cultural, historical and academic collections. Like the museum group Wereldmuseum, and especially the Tropenmuseum, some of these institutions have a history in physical anthropology, and include objects acquired in the service of racial science. Indeed, large collections of human and ancestral remains, for example in medical or anatomical, or broader natural history collections, such as those in the Museum Vrolik, Groningen University Museum or the Anatomical Museum in Leiden, also include ancestral remains collected within a colonial context. These collections were brought together as part of a study in human variation, including variations in what was considered as the normal body, or to prove racialized difference.
Within the Wereldmuseum, ancestral remains were also acquired as part of a tradition of cultural anthropology – in, for example the study of rituals related to death or healing. In some instances, questions of aesthetics played a role in how ancestral remains collections were developed, such as remains acquired privately by artists or art collectors or within, for example, the study of the anthropology of art (Wereldmuseum), or the aesthetics of science (Groningen University Museum or Utrecht University Museum). While predominantly comprised of skeletal material, these collections also include skin, hair, teeth and nail samples.
