The Joint War Organisation (JWO) was a combined operation of the British Red Cross Society and the Order of St John of Jerusalem during the World Wars. It was first created in 1914 and ceased operations when World War I ended in 1919; the organisation was re-formed upon the British entry into World War II in 1939 and was active until its permanent disbanding in 1947. The Joint War Committee (JWC), a non-government administrative body, controlled the JWO and the Joint War Finance Committee managed its finances and concentrated on raising donations and funding.
