The Leeds Blitz comprised nine air raids on the city of Leeds by the Nazi German Luftwaffe. The heaviest raid took place on the night of 14/15 March 1941, affecting the city centre, Beeston, Bramley and Armley. The city was subjected to other raids during the Second World War, but they were relatively minor; only the March 1941 raid caused widespread damage, including to the city's museum and its artefacts.
