The British War Relief Society (BWRS) was a US-based humanitarian umbrella organisation dealing with the supply of non-military aid such as food, clothes, medical supplies and financial aid to people in Great Britain during the early years of the Second World War. The organisation acted as the administrative hub and central receiving depot for items donated from other charities which were then parceled out to its affiliate organizations in the US and to Britain. These donations were raised in the name of the BWRS, rather than in the name of the smaller groups.
