‘Colonialism as a form of violent foreign rule was legitimised by a racist ideology of European superiority,’ says the board that greets you at the Deutsches Historisches Museum in Berlin. In a slightly too small room, hundreds of objects are laid out in clusters along a line representing the Greenwich Meridian, a ‘symbol of Eurocentrism’ and the anchor for a system that European powers used to navigate, conquer and impose borders on large parts of the world. The objects – carved elephant tusks, commercial images for coffee brands, whips – tell the story of the German Empire.
