In 1897, Britain sent a punitive expedition to the Kingdom of Benin, in what is today Nigeria, in retaliation for the killing of seven British officials and traders. British soldiers and sailors captured Benin, exiled its king and annexed the territory. They also made off with some of Africa’s greatest works of art.

The ‘Benin Bronzes’ are now amongst the most admired and valuable artworks in the world. But seeing them in the British Museum today is, in the words of one Benin City artist, like ‘visiting relatives behind bars’. In a time of huge controversy about the legacy of empire, racial justice and the future of museums, what does the future hold for the Bronzes? Paperback, 416 pages.
