The War Requiem, Op. 66, is a British choral and orchestral composition by Benjamin Britten, composed mostly in 1961 and completed in January 1962. The War Requiem was performed for the consecration of the new Coventry Cathedral, which was built after the original fourteenth-century structure was destroyed in a World War II bombing raid. The traditional Latin texts are interspersed, in telling juxtaposition, with extra-liturgical poems by Wilfred Owen, written during World War I.

Edward Benjamin Britten, Baron Britten was an English composer, conductor, and pianist. He was a central figure of 20th-century British music, with a range of works including opera, other vocal music, orchestral and chamber pieces. His best-known works include the opera Peter Grimes (1945), the War Requiem (1962) and the orchestral showpiece The Young Person's Guide to the Orchestra (1945).
