British Museum [SEP] Artefacts taken from other countries
It is a point of controversy whether museums should be allowed to possess artefacts taken from other countries, and the British Museum is a notable target for criticism. The Elgin Marbles, Benin Bronzes, Ethiopian Tabots and the Rosetta Stone are among the most disputed objects in its collections, and organisations have been formed demanding the return of these artefacts to their native countries of Greece, Nigeria, Ethiopia, and Egypt respectively. Parthenon Marbles claimed by Greece were also claimed by UNESCO among others for restitution. From 1801 to 1812, Elgin's agents took about half of the surviving sculptures of the Parthenon, as well as sculptures from the Propylaea and Erechtheum.
