Context of Mania
For a few decades this part of Africa was a colony of Germany, whose brief but brutal rule lasted from 1884 until 1916. Like other colonial powers, Germany established ethnological collections to conserve, study, and display cultural artifacts from its new colonies. Though collecting is an impulse with deep roots in human history, museums as we know them are mostly a 19th-century invention, designed to share the fruits of European exploration and conquest.
Colonialism turned collecting into something of a mania. Just as colonial powers didn’t send explorers to map new corners of the globe for pure love of knowledge, objects didn’t simply fall into museums. Anthropologists, missionaries, merchants, and military officers worked with museums to bring wonders and wealth back to Europe. Curators even sent wish lists along with armed colonial expeditions.
