Tate is an institution that houses, in a network of four art galleries, the United Kingdom's national collection of British art, and international modern and contemporary art. It is not a government institution, but its main sponsor is the UK Department for Digital, Culture, Media and Sport.
The name "Tate" is used also as the operating name for the corporate body, which was established by the Museums and Galleries Act 1992 as "The Board of Trustees of the Tate Gallery".
The gallery was founded in 1897 as the National Gallery of British Art. When its role was changed to include the national collection of modern art as well as the national collection of British art, in 1932, it was renamed the Tate Gallery after sugar magnate Henry Tate of Tate & Lyle, who had laid the foundations for the collection. The Tate Gallery was housed in the current building occupied by Tate Britain, which is situated in Millbank, London.
