Operation Legacy was a programme of the British Colonial Office (later Foreign Office) to destroy or hide files that would implicate the British Empire in wrongdoing, as to prevent them from being used by their ex-colonies.[1][2][3] It ran from the 1950s until the 1970s, when the decolonisation of the British Empire was at its height,[4] and involved at least 23 countries.[5]
